| 摘 要： | OGFC混合料因为空隙率较大,在使用过程中易受水的影响产生剥落、松散.提高OGFC路面水稳性有多种方法,包括掺加石灰或水泥.不同剂量的石灰与水泥对沥青的吸附能力的影响有差异,实验确定最佳油石比.熟石灰的掺加可以通过掺入到沥青或者集料中进行处理.

| Abstract: | A larger void ratio makes OGFC mixture easily effected by water to generate spallation and looseness in the process of use. Many methods are able to improve OGFC pavement water stability, including adding lime or cement. Different doses of lime and cement have different effect on the capacity of asphalt adsorption. The optimal asphalt content is determined by experiment. Hydrated lime can be processed by being added into asphalt or aggregate. |
