rapid-curing asphalt

It is equipped with asphalt return tube, anti-puffing pressure vent valve, anti-aging overhead nitrogen valve, thermometer, volumeter and output asphalt rapid discharge valve and coupling.

配备沥青溢流管、防冒液呼吸阀、防老化顶置充氮阀、温度计、容量计和输出沥青的快速卸料阀及接耦。

With the rapid increase of the mileage of asphalt road, segregation of the asphaltic concrete is therefore becoming increasingly prominent.

鉴于目前高速公路沥青路面通车里程快速增加的同时，沥青混合料离析这一难题也日益突出。

The problems of early destroy about expressway asphalt pavement rapid attenuation of pavement function and decrease of practice application age appear, higher request is put forward to expressway maintenance administration.

高速公路沥青路面的早期破坏，路面使用功能的急速衰减，实际使用年限的降低等问题的出现，对高速公路养护管理提出了更高的要求。
