dc.description.abstractIn August, 1995, The Oklahoma Department of Transportation- (ODOT) completed construction on ODOT Project Number NH-186(190). Briefly, this project consisted of milling and resurfacing a 10.9 km (6.8 mi) long section of U.S. 69. Pavement placed under NH-186(190) included 102 mm ( 4 in) of Type "A" asphalt concrete (AC) and 51 mm (2 in) of Type "B" AC surface. The surface course contained test sections of AC with various asphalt cement binders. Field performance of the various binders is intended to be evaluated and compared. 0.8 km (0.5 mi) long test sections of AC surface were placed. Binders used in the test sections were AC-20 (viscosity grade) asphalt cement modified with Type I-D Polymer, AC-20 asphalt cement with Type 11-C Polymer, and AC-20 with III-Polymer. In other test sections, binders used were AC-20 asphalt cement modified with Type 1-D Polymer and mixed with 25 percent recycled asphalt, unmodified AC-30, and unmodified AC-40. Combinations of fabric reinforcement were also used. Strip membrane was applied over transverse depression cracks, and full-width fabric reinforcement was applied over the traffic lanes. In 0.8 km (0.5 mi) test sections, Strip membrane was applied without full-width fabric, full-width fabric was used without strip membrane, and in one section, neither strip membrane or full-width fabric was used. Various problems have occurred since NH-186(190) began. The project was not completed until fall, 1995. Substandard aggregate was used, resulting in aggregate breaking and crushing in the pavement surface, with large amounts of aggregate in the surface lost to ravelling. These conditions made it necessary to overlay one lane of the Southbound Expressway. The other expressway will likely be overlaid soon. The binder sections to be evaluated were located in the surface course, and it is unlikely that they can be evaluated accurately.
