Ultrahigh-viscosity porous antiskid asphalt drainage surface layer
The invention discloses an ultrahigh-viscosity porous antiskid asphalt drainage surface layer which is a mixture formed by taking ultrahigh-viscosity asphalt as a binding material and open graded broken stone as an aggregate through warm mixing. In the implementation process, the void ratio of the surface layer is finally controlled to be 13%-16%, so that the durability of the drainage pavement isimproved, meanwhile, the water seepage capacity is larger than 4000 mL.min <-1 >, the friction coefficient is within the range of 64-67, and good anti-skid performance is achieved. On the basis of reducing the porosity of the asphalt surface layer, the drainage skid resistance is ensured, and the fatigue durability of the drainage pavement structure can be effectively improved.
本发明公开了一种超高黏多孔抗滑沥青排水表层，是以超高黏沥青为结合料，以开级配碎石为骨料，温拌形成的一种混合料。在实施过程中最终控制表层的空隙率处于13％～16％之间，以提高排水路面的耐久性，同时本发明的渗水能力大于4000mL·min，摩擦系数为在64～67的范围内，具有很好的抗滑性能。本发明在减小了沥青表层空隙率的基础上保证了排水抗滑性能，能够有效提高排水路面结构的疲劳耐久性。
