RESEARCH ON TEMPERATURE REDUCTION OF ASPHALT MIXTURE

Tamotsu YOSHINAKA, Nobuyuki NEMOTO and Toshiaki ICHIHARA

The authors have been studing on the technical improvement for hot asphalt mixture generally used as pavement material, from the point of view of the global warming and environment conservation. The purpose is the development of a new technology of low- heat asphalt mixture enabled to reduse heating temperature at production stage and pavement work. As the result, it was considered that the more temperature reduction is required to enhance the effect of low- heat asphalt mixture. Based on the developed technology, a method enabled to reduse the heating temperature about 50Å`60Å$Bqá(B has established. And it is confirmed that the same quality and execution compared with usual hot asphalt mixture are given by using the improved method.
