【摘要】 针对广东地区高温、多雨、重载车比例高等环境特点,尝试采用GTM法进行沥青混合料设计,并在广梧高速公路河口至平台段铺筑了试验段。结果表明:GTM法设计的普通沥青混合料具有优良的路用性能,其性能指标达到了现行规范对改性沥青的高、低温性能要求,可以有效地解决传统的路面车辙、水损害等早期病害,并能够节省大量的沥青材料资源。更多还原

【Abstract】 Considering environmental characteristics in Guangdong,where it is rainy with high temperature and high proportion of overloaded vehicles,this paper attempts to adopt the GTM method for asphalt mixture design with trial section being paved at Hekou-Pingtai on Guangwu Expressway.The test results show that the ordinary asphalt mixture designed by the GTM method can reach excellent road performance,which can meet the requirement of the existing specifications for high or low temperature performance of modified asphalt.The above-mentioned type of asphalt mixture can effectively solve the early diseases of traditional pavement,such as rutting,water damage,and can also save considerable amount of asphalt materials.更多还原
