SPR 18-559 Asphalt Mixtures Reinforced with Aramid Fibers

Fiber additives in asphalt concrete mixtures purportedly increase the pavement layer's resistance to rutting, thermal and fatigue cracking while increasing the structural capacity of the pavement layer. Aratnid fibers are a class of heat-resistant and strong synthetic fibers that are being incorporated in hot mix asphalt mixtures. The Kentucky Transportation Cabinet will use aratnid fibers to reinforce the hot mix asphalt surface mixture being used during the rehabilitation of US 31 Win Jefferson County. *** This Research Program for the period July 1, 2016 to June 30, 2018 is submitted in compliance with the provisions of Section 307 of Title 23, United States Code, and describes programs and operations for planning activities in the Kentucky Transportation Cabinet (KYTC) and the Kentucky Cooperative Transportation Research Program (KCTRP). This program modifies and updates such programs and is specifically intended to reflect the needs of the Kentucky Transportation Cabinet. It is fully expected that products from this program will also have national applications. The University of Kentucky Transportation Center is the main research group for the the Kentucky Transportation Cabinet. The SPR grant is the funding the is supplied each year for the many topics the Center is asked to research for KYTC The KCTRP is concerned with the development and conduct of a comprehensive research program in cooperation with the U.S. Department of Transportation, Federal Highway Administration (FHWA). In addition to research developed in cooperation with FHWA, the KCTRP may perform other services for the KYTC on a nonparticipating basis. The scope of these services could include activities such as research studies and special investigations of various engineering and operation activities. The Research Program and Implementation Advisory Committee (RPIAC), headed by the State Highway Engineer and coordinated through the Research Coordinator, will give direction to the research program.
