SUGGESTED STEPS TO ASSURE EQUAL EMPLOYMENT OPPORTUNITIES 1. COMPANY POLICY Determine your company's policy regarding equal employment opportunities. Document the policy and post it in a conspicuous place so that it is known to all your employees. Furthermore, disseminate the policy to all potential sources of employees and to your subcontractors asking their cooperation. The policy statement should recognize and accept your responsibility to provide equal employment opportunity in all your employment practices. In regard to dissemination of this policy, this can be done, for example, through the use of letters to all recruitment sources and subcontractors, personal contacts, employee meetings, web page postings, employee handbooks, and advertising.. 2. EQUAL EMPLOYMENT OPPORTUNITY OFFICER Designate an equal employment opportunity officer or, at minimum, assign someone the responsibility of administering and promoting your company's Equal Employment Opportunity program. This person should have a position in your organization which emphasizes the importance of the program. 3. INSTRUCT STAFF '" = Your staff should be aware of and be required to abide by your Equal Employment q!WortunifiProgram. All employees authorized to hire, supervise, promote, or discharge employees or are irWOliied i~uch actions should be trained and required to comply with your policy and the current equal e~me~ oPRohlmity laws. . ~O 0-. r ~ r- fll 4. rn :t>> RECRUITMENT 0 -'_; :x: 0 :S /, <f? (a) Let potential employees know you are an equal opportunity employer. ]illis cancbe done by, identifying yourself on all recruitment advertising as "an equal opportunity employe(. 0-. (b) Use recruitment sources that are likely to yield diverse applicant pools. Word-of-mouth recruitment will only perpetuate the current composition of your workforce. Send recruitment sources a letter annually which reaffirms your commitment to equal employment opportunity and requests their assistance in helping you reach diverse applicant pools. (c) Analyze and review your company's recruitment procedures to identify and eliminate discriminatory barriers. (d) Select and train persons involved in the employment process to use objective standards and to support equal employment opportunity goals. (e) Review periodically job descriptions to make sure they accurately reflect major job functions. Review education and experience requirements to make sure they accurately reflect the requirements for successful job performance. (f) Review the job application to insure that only job related questions are asked. Ask yourself "Is this information necessary to judge an applicant's ability to perform the job applied for?" Only use job-related tests which do not adversely affect any particular group of people. (g) Monitor interviews carefully. Prepare interview questions in advance to assure that they are only job related. Train your interviewers on discrimination laws. Biased and subjective judgments in personal interviews can be a major source of discrimination. (h) Improve hiring and selection procedures and use non-biased promotion, transfer and training policies to increase and/or improve the diversity of your workforce representation. Companies must make sure procedures for selecting candidates for promotion, transfer and training are based upon a fair assessment of an employee's ability and work record. Furthermore, all companies should post and otherwise publicize all job promotional opportunities and encourage all qualified employees to bid on them. CC-4 I ~ 1 !~~~tt -.;;:;::.....

The tack coat emulsion may be diluted with water to improve applicatiClR'. A liglqO application of sand cover may also be required, but this is anticipated only for excessive \D application rates, breakdowns, anc;t short sections remaining at the end of a day's run. On hJghways being constructed under traffic, safety and convenience to the public without soiling their vehicles shall be a controlling factor. Tack coat shall be adequately cured prior to placement of the HMA. Tack coat applications shall be limited in length, to minimize inconvenience to the public. They shall be kept within the hot mixture placing work area that is controlled by f1aggers at each end, and shall be planned so that they will be covered with hot mixture when the work area is opened to traffic at the end of the day's work. If the tack coat surface becomes dirty from weather or traffic, the surface shall be thoroughly cleaned and, if necessary, retacked. The vertical face of exposed, longitudinal joints shall be tacked as a separate operation, before the adjoining lift is placed, at a rate from 0.10 to 0.15 gallon per square yard (0.5 to 0.7 Um2). The vertical surfaces of all fixtures, curbs, bridges, or cold mixtu~e with which the hot mixture will come in contact shall be lightly painted or sprayed tei facilitate a tight joint with the fresh mixture. 3. Fabric Reinforcement. When fabric reinforcement is required, the locations wili be designated in the contract documents. Fabric shall not be placed on a wet or damp surface or when the road surface is less than 500F (10oC). Fiberglass fabric sl1?lI be applied only with an adhesive recommended by the manufacturer. Fabrics with an adhesive backing shall be placed in accordance with the manufacturer's recommendations. Other fabrics shall be placed with a heavy coat of the asphalt binder grade used in the HMA mixture applied at a rate of 0.20 to 0.25 gallons per square yard (0.9 to 1.1 Um2) and at a temperature between 29soF and 31soF (1450C to 1600C). The fabric reinforcement shall be placed in accordance with the contract documents (full width or individual crack or joint treatment). The fabric shall be placed immediately following the adhesive SS-01014, Page 8 of 21 or asphalt binder placement under the fabric; Placement may be by hand or by a mechanical method specifically designed for this purpose. Precautions shall be taken to avoid wrinkles in the fabric and to insure that air bubbles are removed without breaking the fabric. Wrinkles or folds which cannot be removed by brushing shall be cut and lapped to provide a smooth surface. Additional adhesive or asphalt binder may be required to produce a tight, bonded surface. When applied full lane width, the minimum transverse and longitudinal lap shall be 12 inches (300 mm). The Contractor shall avoid application of the tack coat oiler longitudinally placed fabric. Traffic shall not be allowed over the fabric during placement and during curing of the adhesive material to avoid damage to the fabric. A light application of HMA mix material may be hand sprinkled on the 'fabric to prevent damage from necessary equipment traffic. Fabric that is damaged or soiled prior to HMA overlay shall be repaired at no additional cost to the Contracting Authority, when directed by the Engineer.

A wire or string line shall 'be used to guide the finishing machine and to maintain alignment. Edge alignment irregularities shall be corrected by hand methods immediately after they occur. The contract documents will show the total thickness to be placed. Spreading of the mixture shall be at such a rate that, when compacted, the layer(s) will be substantially of the thickness and dimensions required to produce the required thickness. The minimum layer thickness is three times the designated mix size. Tf:Ie compacted thickness of the top layer shall not..be greater than 3 inches (75 mm). This restriction shall not apply to HMA shoulders. The maximum compacted thickness of lower layers may exceed 4 inches (100 mm) if it is demonstrated that the thicker layers have satisfactory density. The riding characteristics of the thicker layers shall be within reasonably close confonnance to that expected from a 3 inch (75 mm) layer. Each layer shall be completed to full width before succeeding layers are placed. At the close of each working day, the roadbed shall be free of any construction equipment. The Contractor shall not spread more mixture than can be compacted and finished in daylight hours of the same working day. While operating on the road surface, use of kerosene, distillate, other petroleum fractions, or other solvents, for cleaning hand tools or for spraying the paver hopper will not be pennitted. Containers of cleaning solution shall not be carried on or near the paver. When a solvent is used, the paver shall not be used for at least 5 hours after this cleaning. The Contractor shall be responsible for collecting and removing all cleaning materials and cleaning residue from the project and plant site. The cleaning material and residue shall become the property of the Contractor. SS-Dl014. Page 11 of 21 Whenever practicable, all mixtures shall be spread by a finishing machine. Irregular areas may be spread by hand methods. The hot mixture shall be spread unifonnly to the desired depth with hot shovels and rakes. Loads shall not be dumped faster than they can be spread properly. Wor1<ers shall not stand on the loose mixture while spreading. After spreading, the hot mixture shall be carefully smoothed to remove all segregated coarse aggregate and rake mar1<s. Rakes and lutes used for hand spreading and smoothing shall be of the type designed for use on HMA mixtures. D. Compaction. Each layer shall be promptly and thoroughly compacted. Mechanical tampers shall be used for areas inaccessible to the rollers. The overall rolling procedure and compactive effort shall produce a surface free of ridges, marks, or bumps and shall be subject to approval of the Engineer. There are two classes of compaction, Cla&s I and Class II. Class I rompaction is intended for u~eon: Secondary highways. Class II compaction is intended for resurfacing paved shoulders, temporary crossovers, runarounds, and for other situations where Class I is not specified. ....., For Class I compaction, the roadway density (percent of laboratory density) will be ~ed on am density obtained from the Quality Control Program for that day's mixture. . ;;E 0 ~ , )>- [;i 11 1.

The Contractor shall assume the responsibility to cease operations, including not incorporating produced material which has not been placed. The process shall not be started again until the Contractor notifies the Engineer of the corrective action proposed. C. Construction. 1. Density. Density samples shall be taken from the compacted mixture and tested not later than the next working day following placement and compaction. A lot shall be consi<;fered as. one layer of one mixture placed during a day's operation. The Engineer may approve classifying multiple layers of construction placed during a single day as a lot provided only one mixture was used. When the day's operation is 2500 square yards (2500 m2) or less, or the day's operation is 500 tons (500 Mg) or less, or when the mixture is being placed in irregular areas, or for wedge, leveling, or strengthening courses, the Engineer may waive sampling for density provided compaction has been thorough and effective. Seven density samples will be taken for each lot The length laid in each lot shall be divided into seven approximately equal sections and one sample will be obtained at a random location in each section. If a sample is damaged or measures less than 70% or more than 150% ofthe Intended thickness, an alternate sampling location will be determined and used. Samples shall not be taken less than 1 foot (300 mm) from the edge of a given pass of the placing equipment or from rurKluts or areas adjacent to day's work joints or structures. -- SS'{)1014.

If one of the density test values from a lot is an outlier, identified in accordance with the procedure described in Materials I.M. 508, the outlier value shall not be used to determine the quality index, The quality index shall be determined using the remaining density test values. If only one laboratory density value is obtained that day, combine that value with the next day's test results to evaluate both days' production. If two or more laboratory density values are obtained that day, then the average of those tests alone shall be used. If a significant mix change has been made, only the appropriate laboratory density values should be used with the .-.0 . = corresponding density cores. 0 ~ -';;0 -n ~- ,.., Il 2.

Thickness samples will be taken full depth of the _.~- completed course and after measurement, the density samples for the top layer shall be removed by the Contractor from the core. If any of the measurements for a lot is less than the designated thickness, the quality index for thickness of that lot will be determined by the following formula: QI _ Average 1biclmess MEASURED -(1biclmess PLAN -0.50) THICKNESS - Maximum 1biclmess MEASURED - Mininn.nn lbickness MEASURED When the day's operation is 2500 square yards (2500 m2) or less, or the mixture is being placed hi irregular areas or next to structures, the Engineer may waive sampling for thickness provided there is reasonable. assurance that the pavement conforms to the required thickness. When the quality index falls below 0.00, the Engineer may declare the lot or parts of the lot defective. D. Sampling and Testing. The Contractor shall calibrate and correlate the testing equipment with prescribed procedures. Sampling and testing shall conform with specified testing procedures as listed in the Materials I.M. and applicable Specifications. When the results from a lab a~ used for product acceptance, the lab shall be qualified. All samples shall be identifi ed, stored and retained by the Contractor for the Contracting Authority until the lot is accepted. The Contracting Authority may acquire these samples for comparative, verification, or assurance testing. All samples shall be identified by a system approved by the Engineer. SS-01014.

All samples of asphalt binder and tack coat material, shall be identified and promptly delivered to the appropriate laboratory, as designated by the Engineer. Samples of loose HMA mixture shall be taken behind the paver, weigh at least 50 pounds (25 kg), and shall be transported to the test facility in a way to retain heat to facilitate sample splitting procedures, The tests for mixture properties shall be conducted on representative portions of the mix, split from the larger sample of mix. After splitting of the sample is completed in the Contractor's QM-A laboratory, the remainder of the sample, approximately 30 pounds (15 kg) shall be retained for laboratory testing by the I~boratory designated by the Contracting Authority. When requested by the Engineer, normally once per day. an additional 50 pounds (25 kg) box sample will be required for correlation and validation testing. - Samples shall be split in accordance with Materials I.M. 357c All test results and calculations shall be recorded and documented on data sheets approved by the Contracting Authority. Specific test results shall be recorded on a daily summary sheet approved by the Contracting Authority. The Daily Quality Control Summary Sheet shall also include a description of quality control actions taken (adjustment of cold feed percentages, changes in JMF, etc.). The Contractor shall FAX, or by other method approved by the Engineer, the daily quality control summary sheet to the appropriate Iowa DOT District Materials Engineer or Engineer daily. A copy of the electronic file containing project information generated during the progress of the work shall be furnished to the Engineer at project completion. 2. Finished Pavement Requirements. The Contractor shall cut samples from any course or finished pavement for tests of density, thickness, or composition, by sawing with a power driven masonry saw or by drilling a minimum 4 inch (100 mm) nominal diameter core.

Acceptance, Correlation, and Quality Assurance Testing. The Contractor's quality control test results will be compared and correlated to the Engineer's test results on a regular basis using guidelines and tolerances set forth In Materials I.M. 208, Appendix C; 216; and 511. . If satisfactory COrrelation exists between the Contractor's test results and the Engineer tests, the Contractor's results will be used. Disputes between the Contractor's and Engineer's test results, on one sample or one test of one sample, will be resolved by repeated testing of the same sample or additional testing of another sample. When repeated andlor additional sampling fails to resolve a dispute, a third materials laboratory designated by the Contracting Authority will act as a reference laboratory and perform additional testing as necessary to resolve the dispute. SS-01014, Page 19 of 21 The Engineer will select, at random, a split portion of one or more of the daily hot mix production samples. Some or all of the samples selected will be tested in the materials laboratory designated by the Engineer. The Engineer will test as many of the samples as necessary to establish a correlation. The Engineer will select one daily set of cores at random each week. These will be tested at the materials laboratory designated by the Engineer. Cores from the initial production will also be tested by the Contractor and the Engineer for correlation and validation of results, ,..., = 01014.05 METHOD OF MEASUREMENT 0 ~ . ~O ~ The Engineer will measure the quantities of the various items of work involved in placerooAt-bf bliOl"in<lli9 mixtures in accordance with the following provisions: 0 -<. r;;..

The asphalt binder quantity added to the storage tank shall be computed from a supplier certified transport ticket accompanying each load. The quantity of asphalt binder not used in the work will be deducted. When the quantity of asphalt binder in a batch is measured by weight (mass) and is separately identifi.ed by automatic or semi-automatic printout, the Engineer may compute from this printout the quantity of asphalt binder used. By mutual agreement, this method may be modifi.ed when small quantities or intermittent operations are involved. The Engineer will calculate and exclude the quantity of asphalt binder used in mixtures in excess of . the tolerance specified in Article 01014.04, B, 2, of this Supplemental Specifi.cation.
