Development of Test System for Anti-cracking Performance of Semi-rigid Base Asphalt Pavement

摘要:

为更加精确的评价半刚性基层沥青路面的抗裂性能，系统分析了沥青路面开裂机理，依此设计抗裂测试系统的功能设计，明确其具体构造要求，并对其框架及细部进行了详细设计，基于层底应力敏感性分析确定测试的控制模式及参数范围，依据仪器的工作原理、检验指标，进行了温控系统、横向拉伸系统、竖向剪切系统设计，开发与仪器匹配的计算机辅助分析软件并进行测试。测试系统为半刚性沥青路面的抗裂性能的定理评价提供了设备支撑。

Abstract:

In order to more accurately evaluate the crack resistance of semi-rigid base asphalt pavement, the cracking mechanism of asphalt pavement is systematically analyzed, and the functional design of the anti-cracking test system is designed based on this. The specific structural requirements are clarified, and its frame and details are carried out. Detailed design, based on the bottom stress sensitivity analysis to determine the test control mode and parameter range, based on the instrument's working principle and inspection indicators, the temperature control system, transverse stretching system, and vertical shearing system are designed and developed to match the instrument Computer-aided analysis software and test. The test system provides equipment support for theorem evaluation of the anti-cracking performance of semi-rigid asphalt pavement.
