| 摘 要： | 目前对沥青混凝土路面坑槽、裂缝等病害的修补多采用热拌沥青混合料的形式，温度要求较高。冷补沥青混合料可以在较低的温度下施工，具有高效、节能、快速、及时等优点，可满足路面坑槽修补的需要。根据冷补沥青材料的技术特点，分析混合料强度形成的机理，通过初始强度试验和成型强度试验对混合料的强度进行研究并提出建议。

| Abstract: | Currently the asphalt concrete pavement pit slots and crack are patched by heating asphalt mixtures mostly and needs higher temperature. Cold patching asphalt mixture may be constructed under lower temperature, and it has high efficiency, energy saving, fast and prompt technical characteristic. It may satisfy the need of pavement pit slot patching. This paper has analyzed strength formation mechanism of mixtures according to cold patching asphalt mixture technical characteristic, studied mixtures strength and gave the proposal through the initial strength experiment and final strength experiment. |
