基于结构性能的冷再生上基层材料组成研究

通过点对点测弯沉的方法,计算出了沥青路面各结构层的模量.以结构层模量为基础,对水泥-乳化沥青冷再生上基层路面结构进行了有限元分析,提出了冷再生混合料材料组成的设计要求,并进行了冷再生混合料材料组成设计和试验路验证.结果表明:用该方法设计的冷再生混合料对沥青路面进行维修,可以提高路面的使用寿命和性能.

Material Composition Research of Cold Recycled Upper Base Based on Structure Performance

Every asphalt structure layer's modulus was calculated by deflection survey with point to point.Based on structure layer modulus the material composition design requirements for cold recycled mixtures was put forward through finite element analysis of cement and emulsified asphalt cold recycled upper base.According to these requirements the material composition design of cold recycled mixtures was made and the test roads were built for verification.The results indicate that life and performance of asphalt pavement is improved by the maintenance of the cold recycled mixtures which was designed by the method.
