Appendix S: New Jersey <strong>Asphalt</strong> <strong>Rubber</strong> <strong>Specifications</strong><br />
402.01 DESCRIPTION<br />
SECTION 402.01 IS CHANGED TO:<br />
SECTION 402 –HMA FRICTION COURSE<br />
This Section describes the requirements for constructing open-graded friction courses<br />
(OGFC), modified open-graded friction courses (MOGFC) and asphalt-rubber open-graded<br />
friction courses (AR-OGFC).<br />
402.02 MATERIALS<br />
402.02.01 Materials<br />
THE FOLLOWING IS ADDED: Provide materials as specified:<br />
<strong>Asphalt</strong>-<strong>Rubber</strong> Open-Graded Friction Course................................................. 902.07<br />
402.02.02 Equipment<br />
THE FOLLOWING IS ADDED: Provide equipment as specified:<br />
<strong>Asphalt</strong>-<strong>Rubber</strong> Binder Blending Equipment.................................................. 1009.03<br />
402.03 CONSTRUCTION<br />
THE FOLLOWING IS ADDED AFTER 402.03.01:<br />
402.03.02 AR-OGFC<br />
A. Paving Plan. At least 20 days before beginning placing the AR-OGFC, submit to the<br />
RE for approval a detailed plan <strong>of</strong> operation as specified in 401.03.03.A.<br />
Do not begin paving until the RE approves this plan. Submit an adjusted paving plan<br />
before making adjustments to the paving operation.<br />
B. Weather Limitations. If within the 12 hours before paving the National Weather<br />
Service locally forecasts a 50 percent chance or greater <strong>of</strong> precipitation during the<br />
scheduled placement, postpone the placement <strong>of</strong> AR-OGFC. Do not place AR-OGFC<br />
if it is precipitating and do not allow trucks to leave the plant when precipitation is<br />
imminent. The Contractor may resume paving operations when the chance <strong>of</strong><br />
precipitation is less than 50 percent and the surface is dry.<br />
Do not pave if the surface temperature <strong>of</strong> the underlying pavement is below 50 °F.<br />
C. Test Strip. Construct a test strip as specified in 401.03.03.C. The Department will not<br />
require quality control cores or nuclear density testing.<br />
D. Transportation and Delivery <strong>of</strong> AR-OGFC. Transport and deliver AR-OGFC as<br />
specified in 401.03.03.D.<br />
E. Spreading and Grading. Apply tack coat as specified in 401.03.02. Place AR-OGFC<br />
at a laydown temperature between 275 °F and 330 °F maximum. Spread and grade<br />
