INFLUENCES OF ANGULARITY OF FINE AGGREGATE ON DURABILITY OF ASPHALT CONCRETE PAVEMENT

Japan Highway Public Corporation (JH) constructs and operates national expressways as a nationwide corporation administrating toll roads on behalf of the Government. At the end of the fiscal year 1996 the Japanese expressways in operation extended 6100 km in length and played an indispensable part in both the domestic economy and daily life of the Japanese people. In asphalt pavements with a share of 93 percent of the road surface in JH, flow rutting has been the most major factor which needs rehabilitation. Although modified asphalt has been increasingly used as a countermeasure against flow rutting, use of this material makes temperature control difficult during mixing and construction besides its higher cost. Therefore a countermeasure that is more economical and more readily constructed is strongly needed in JH. According to the Foreign Technology Introduction Project which was conducted in JH in 1992, it was found that in France crushed stone is exclusively used as aggregate for asphalt mixtures to increase their flow resistance. This is probably because its angularity will give higher friction within the mixtures and therefore will resist flow rutting in situ. Because there has been no criteria on the particle shape of fine aggregate (hereafter called sand) in Japan, selection of angular sand was judged worthy of implementation in JH. This report describes the development of a particle shape test appropriate for the Japanese sand for its implementation in JH and influences of angular sand on flow resistance in asphalt pavements.
