摘要
采用贝雷设计原理进行了破碎卵石的级配设计,并采用马歇尔设计方法,确定了最佳级配及其沥青含量。针对破碎卵石与沥青粘附性较差的特点,采用水泥作为抗剥落剂,进行了室内性能验证,试验结果证明破碎卵石沥青混凝土路用性能能够满足规范要求,可以在路面生产中应用。
This paper adopted Bailey method for gradation design of broken cobble asphalt mixture. The optimum gradation and the content of asphalt were determined by Marshall design method. Because the adhe- sion of broken cobble and asphalt was bad, the performance of asphalt mixture was tested by adding cement as anti - stripping agent. The results showed that the pavement performance of broken cobble asphalt mixture met the requirements of specification and could be applied in pavement production.
