为有效预防城市道路交叉路口等特殊路段发生车辙类工程病害及提高路面的耐久性,提出了以开级配沥青混合料和水泥砂浆结构复合的OGBC-20有机水硬性胶结沥青混合料,进行了OGBC配合比设计,水泥砂浆的抗压强度试验、开级配沥青混合料马歇尔试件的谢伦堡沥青析漏试验、肯塔堡飞散试验,OGBC-20马歇尔试件的稳定度试验、冻融劈裂试验、抗压强度试验以及高温车辙试验、低温劈裂试验。试验结果证明:OGBC-20混合料相比普通沥青混合料具有较好的水稳定性和低温抗裂性,其高温稳定性具有绝对优势。
In order to effectively prevent the occurrence of rutting diseases and improve the durability of road surface during the special road sections such as urban road intersections, an OGBC-20 organic hydraulic cementitious asphalt mixture with open-graded asphalt mixture and cement mortar structure was proposed OGBC mix design, compressive strength test of cement mortar, open pitched asphalt mixtures Marshall specimens of the Schellingborough asphalt leak test, Kentucky scattered test, OGBC-20 Marshall specimen stability test, freeze-thaw Splitting test, compressive strength test and high-temperature rutting test, low temperature splitting test. The test results show that: OGBC-20 mixture has better water stability and low temperature crack resistance than ordinary asphalt mixture, and its high temperature stability has an absolute advantage.
