Comparative Study on GTM Method and Marshall Mixes Design Method for Large Stone Asphalt Mixes
Three types of aggregate gradation with different nominal maximum size were designed by Bailey method for large stone asphalt mixes (LSAM). The optimum asphalt content was then determined by Gyratory Testing Machine (GTM) method and Marshall method, respectively. A series of tests were carried out to investigate the performance of the obtained LSAM. The optimum asphalt content(OAC), volume of voids(VV), voids in mineral aggregate(VMA) and voids filled with asphalt(VFA) of specimens prepared by GTM method showed smaller values whereas bulk density is larger. Furthermore, higher temperature stability and poorer crack resistance at low temperature of the former can also be observed.
