Comply with Section 00740 of the Standards Specifications modified as follows:

00740.10 Materials – Replace the last sentence of this subsection with the following:

Provide a copy of the JMF to the Project Manager before paving. The contractor shall utilize Level 3, ½ Inch Dense Graded, lime treated ACP or alternative treatment as outlined in sections 00745.11(d) & (e).

Add the following subsection:

00745.11(d) Aggregate Treatment - Latex Polymer - A latex polymer Aggregate treatment Material may be used to treat new crushed Aggregates instead of lime if Tensile Strength Ratio test results on the mixture with the latex polymer treatment at the JMF meet the minimum criteria in 00745.13(a).

(1) General:

a. Provide a system to automatically meter the latex emulsion at the proper rate and apply the emulsion uniformly to the Aggregate prior to the addition of the asphalt cement. Follow manufacturer's recommendations to set up, adjust, and calibrate the Equipment.

b. Demonstrate to the Engineer's satisfaction that the required application rate of latex solids is being met. If it is not, take corrective action. Document and notify the Engineer of the corrective action.

(2) Material - Use latex polymer emulsion concentrate meeting the following:

Minimum Maximum Test Method

Provide a quality compliance certificate for the polymer latex emulsion concentrate to the Engineer according to 00165.35.

(3) Application Rate - Apply the latex emulsion to achieve a minimum of 0.75 pounds of latex solids per Ton of new Aggregate (0.0375%) for dense graded mixtures and a minimum of 0.50 pounds of latex solids per Ton of Aggregate (0.025%) for open‑graded mixtures. Higher application rates may be required to meet minimum TSR limits. Determine application rate during mix design testing.

(4) Treatment During ACP Production:

a. Adjust Aggregate moisture content to meet the manufacturer's recommendation for emulsion application. Apply the latex emulsion at the minimum rate specified above or at a higher rate if TSR testing indicates a higher rate is required.

b. Apply the latex emulsion to the Aggregate just prior to entry into dryer drum. Mix Aggregate with the emulsion in a pugmill or in the dryer drum prior to application of asphalt cement. Heat Aggregates to at least 250 °F after treatment and prior to addition of asphalt cement.

Add the following subsection:

00745.11(e) Liquid Anti-Stripping Additive – An asphalt cement liquid anti-stripping additive (LASA) may be used instead of lime treatment of Aggregate.

(1) General – For LASA to be considered for use, meet the following criteria:

· Be designated as an asphalt anti-strip additive, with test results posted on the Warm Mix Asphalt Technologies category on the AASHTO Product Evaluation and Audit Solutions (APEAS) website.

· APEAS test results indicate an increase of 10 percent or greater in TSR (AASHTO T 283) performed on durable Aggregate, not limestone.

· Be approved for use by another State DOT as an anti-stripping additive.

If a product meets these criteria, it may be used in the JMF development according to the ODOT Contractor Mix Design Guidelines for Asphalt Concrete. The standard addition rate of LASA for the JMF is the rate used in the APEAS testing. If no rate is published, the minimum rate will be 0.5% of the virgin binder. If the APEAS published rates are 0.5% of total binder or higher, the minimum rate may be reduced to 0.5% of the virgin binder.

Approval of the JMF is also dependent on Hamburg wheel-track testing results conducted at the ODOT Central Materials Laboratory. When tested according to AASHTO T 324 for 20,000 passes at a test temperature of 50 °C the minimum requirements are:

(2) Addition to Asphalt Cement – Blend the LASA at the asphalt terminal prior to delivery to the mixing plant. Use LASA compatible with the asphalt cement. Comply with all asphalt cement requirements for the blended product. Do not change the LASA addition rate without prior approval from the Engineer.

(3) Field Testing During Production – At the Agency’s discretion, production mixture may be tested at the Central Materials Laboratory. Failure to meet the criteria listed above may require a change in addition rate, a change of approved LASA, or lime‑treatment of Aggregate to continue production.

00740.12 Asphalt Cement – Replace the first sentence of the first paragraph with the following:

Use PG64-28 unless otherwise specified in the contract documents or approved.

Add the following subsection:

00740.20 General – Provide Pavers according to Section 00744.23 and Compactors according to Section 00744.24.

00740.44 Placing Asphalt Concrete – Replace the first paragraph of this subsection with the following:

Place the Commercial Asphalt Concrete Pavement (CACP) according to Sections 00744.40, 00744.41, 00744.42, 00744.43, 00744.44, 00744.45, and 00744.60.

(feet)

Place the wearing course mixture in a single lift at a nominal compacted thickness of 2.5 inches and 12 feet wide per lane. Grind and inlay inside of striping lines and rumble strips. Existing fog line stripes, center line, and rumble strips are to remain.
