| 摘 要： | 为使层间粘结材料满足路面耐久性要求,根据沥青路面养护层的应用条件进行分析。采用直剪试验可直接评价层间粘结作用;通过设计复合马歇尔试件的成型方法,并对比复合车辙板取芯试件的剪切试验结果,表明前者具有更好的稳定性;水煮粘附性试验能有效地表征粘层材料的抗水剥落性能,是层间粘结性能的重要影响因素,通过分析乳化沥青的粘附性试验,以沥青的质量裹覆率代替面积裹覆率进行指标的量化能更加准确有效地评价其抗剥落性,其试验结果同样具有良好的稳定性。

| Abstract: | According to the application condition of asphalt pavements, the direct shear test was used to evaluate the interlaminar bonding effect in order to meet the pavement durability requirements. The composite Marshall specimen molding method was designed and its results on core specimens were contrasted with the composite plate shear test results. It is found the former has better stability. It is also shown that the boiled adhesion test can effectively characterize the water stripping resistance of adhesive layer materials, which is one of the important factors affecting the bonding performance between layers. Through the analysis of the adhesion test results of emulsified asphalt, the quantified index of asphalt quality, instead of the area coating rate, can evaluate the stripping resistance more accurately and effectively and the test results also have a good stability. |
