不粘轮防水粘结层在高速公路中的应用

摘要:

针对乳化沥青作为防水粘结层在实际施工中存在因粘轮受到破坏的现象,本文通过室内试验和现场试验对不粘轮沥青防水粘结层的工程应用进行研究,对其常用性能以及路用情况进行检测,并与热喷改性SBS沥青+碎石粘结层的性能进行对比分析。结果表明：相较于热喷改性SBS沥青+碎石粘结层,不粘轮乳化沥青附着力拉拔强度高,抗施工损伤的能力更优,具有一定工程应用的前景。

Abstract:

In view of the phenomenon that emulsified asphalt as waterproof adhesive layer is damaged due to adhesion wheel in actual construction, this paper studies the engineering application of non adhesion wheel asphalt waterproof adhesive layer through indoor test and field test, detects its common performance and road use situation, and compares and analyzes the performance of thermal spray modified SBS asphalt + gravel adhesive layer. The results show that: compared with the thermal spray modified SBS asphalt + macadam adhesive layer, the non stick wheel emulsified asphalt has higher pull-out strength and better construction damage resistance, which has a certain engineering application prospect.
