慢裂乳化沥青的研制

On preparation of slow-crack elestex

公路的黑色路面由于行车荷载的增大 ,磨损加剧 ,加之自然气候的风化 ,使路面材料易于老化 ,路面开裂变得十分突出 ,稀浆封层被认为是一种行之有效的路面处治方法。稀浆封层的关键材料———慢裂乳化沥青 ,目前国内尚未有理想的产品。为此 ,我们总结分析了影响沥青乳液骨料后破乳速度的因素 ,认为可以通过复配的方法来减缓这一破乳过程。

The black pavement of highway was worn seriously due to the heavy load of vehicle.Furthermore,the climate weathering contributes much to the ageing and crack of road surface.It is suggeated slurry sealing is a good way to treat the crack.But the critical materical--slow-crack elestex with high quality can't be manufactured home.In view of this,the factors affecting post demulsification speed of emulsion aggregate was analyzed.It is thought that demulsigication can be slowed by building method.
