摘　　要：连续配筋混凝土、沥青面层之间的黏结能够直接影响复合式路面的综合质量,对其进行研究具有一定现实意义。以同步碎石封层抗剪能力为研究对象,采用“水泥混凝土+封层+沥青面层”的复合结构,以试验温度、集料粒径等内容为变量,进行CRCP-AC的路面层间同步碎石封层抗剪能力测试实验。结果表明,试验温度、集料粒径等变量均会对抗剪强度产生显著影响,其中,9.5 mm~13.2 mm粒径的碎石在实践中能够显著提升路面同步碎石封层抗剪切强度。The bonding between continuously reinforced concrete and asphalt pavement can directly affect the comprehensive quality of composite pavement,and studying it has certain practical significance.This article takes the shear resistance of synchronous crushed stone sealing layer as the research object,adopts a composite structure of“cement concrete+sealing layer+asphalt surface layer”,and takes experimental temperature,aggregate particle size and other contents as variables to conduct a test experiment on the shear resistance of CRCP-AC pavement interlayer synchronous crushed stone sealing layer.The results indicate that variables such as experimental temperature and aggregate particle size have a significant impact on the shear strength.Among them,crushed stones with particle sizes of 9.5 mm~13.2 mm can significantly improve the shear strength of synchronous crushed stone sealing layers on road surfaces in practice.
