摘要
以河源205国道维修为背景,通过碎石洒铺粒径、沥青洒铺量、碎石洒铺量等因素分析了高粘沥青粘结性能,并通过组合结构进行全厚式车辙分析,最终确定了高粘高弹改性沥青洒铺量为2.2～2.5kg/m2,碎石洒布量为14～16kg/m2,碎石洒铺粒径为9.5～13.2mm,粘结应力吸收材料具有最为优良的使用性能。
Based on the application of G205 Road in Heyuan,SAMI made of high-viscosity and high-elasticity asphalt was prepared.The grain size and amount of crush rocks,the dosage of asphalt were analyzed and determined.The full depth wheel tracking performance of the pavement structure was tested.The optimal proportion for SAMI made of high-viscosity and high-elasticity asphalt is：asphalt dosage 2.2～2.5 kg/m2 ,crush rocks 14～16 kg/m2 ,the size of crush rocks 9.5～13.2 mm.
