乳化沥青下封层材料的试验研究

Experimental Study on Emulsified Asphalt Material for Lower Seal Coat

乳化沥青下封层材料的物理力学性能目前规范无明确的试验方法及技术要求,为此本文针对下封层乳化沥青材料的实际情况,对不同乳化沥青指标进行了室内试验,并开发了一套测试物理力学性能的试验方法,采用开发的试验方法对不同乳化沥青的抗剪强度、抗拉拔、防渗水、渗透性进行了试验研究,并进行了分析。

There have been no specific test methods and technical requirements on the physical and mechanical property of the emulsified asphalt material for lower seal coat specified by recent technical codes. So according to the recent situation of the emulsified asphalt materials for lower seal coat, in this article some indoor experiments for different emulsified asphalt indexes have been done and a set of experimental methods for testing physical and mechanical properties have already been developed. By use of the methods we made a experimental study on the shear strength, resistance to drawing, water seepage proofing and also permeability for different emulsified asphalts, and also made analysis on the testing results.
