透水沥青高粘剂的施工注意事项
1)注意地基密度
1) Foundation density
为了能够让透水沥青高粘剂有效的发挥作用,在使用透水沥青高粘剂之前,要将地基的密度控制在90-95%之间,因为地基过于密实会影响路面的渗透性,直接导致路面的排水性变差;过于稀松的话,会造成路面由于日晒雨淋发生移位,致使道路的寿命会变短。
In order to make the permeable asphalt high-viscosity agent play an effective role, before using the permeable asphalt high-viscosity agent, the density of the foundation should be controlled between 90-95%, because the compactness of the foundation will affect the permeability of the pavement, which will directly lead to poor drainage of the pavement; if too loose, it will cause the pavement to shift due to sunshine and rain, which will shorten the life of the road.
2)遵循混合比例
2) Follow the mixing ratio
透水沥青高粘剂的配比比例是关键性因素,所以在沥青里面加入透水沥青高粘剂的时候,需要将比例控制在一个合理的范围,才能让透水沥青高粘剂展现出良好的强度和渗透性,防止泥浆流到骨料里造成孔隙堵塞问题,增加透水沥青高粘剂的实用效果。
The proportion of permeable asphalt high-viscosity agent is the key factor, so when the permeable asphalt high-viscosity agent is added into the asphalt, it is necessary to control the proportion in a reasonable range, in order to make the permeable asphalt high-viscosity agent show good strength and permeability, prevent slurry from flowing into aggregate causing pore plugging problem, and increase the practical effect of the permeable asphalt high-viscosity agent.
3)防止出现固化
3) Prevent curing
施工时应该注意透水沥青高粘剂的固化时间,透水沥青高粘剂在调配出来后,会在大约半个小时后凝固成型,固化时间和收缩比较快,因此在沥青路面施工的现场,要注意透水沥青高粘剂与沥青在搅拌机里面快速搅拌均匀后,应第一时间浇筑到地面同时用压路机快速来回压平。
During construction, attention should be paid to the curing time of pervious asphalt high-viscosity agent. After mixing, pervious asphalt high-viscosity agent will solidify and form in about half an hour. songjiaoyou.07858.net diandongm.89ix.comfangdaomenw.89ix.com fengmao.89ix.comjialouyi.89ix.comtiaojiefad.89ix.comThe curing time and shrinkage are relatively fast. Therefore, on the site of asphalt pavement construction, attention should be paid to the rapid mixing of pervious asphalt high-viscosity agent and asphalt in mixer, and the first time should be poured to the ground while using road roller fast. Flatten back and forth.
