The objective of this study is to evaluate the application of a cold asphalt rejuvenating agent, 'Koppers Company Bituminous Pavement Rejuvenator' to an ID-2 wearing bituminous concrete pavement. The rejuvenator is to increase the penetration and ductility of the existing asphalt to improve the durability of the pavement. The project is located on Legislative Route 70, Traffic Route 28, Allegheny County. The material was applied by distributor at an average application rate of .025 gal./sq. yd. and dusted with stone screenings. Skid tests were performed before and after the application. These tests indicate that the skid numbers were lowered from an average of 54 before application to 21 after application. Skid numbers did not recover to an acceptable level, over 37, until after four weeks of service. It is recommended that no additional evaluation be made on this product and that it not be-approved for use on Department projects.
