Abstract

The invention relates to a super-hydrophobic anti-ice-coagulation compound asphalt face layer structure and a preparation method thereof. A pavement is composed of an anti-ice-coagulation functional layer, an asphalt face layer structure body and an epoxy bonding layer. The anti-ice-coagulation functional layer is prepared through a hydrophobic material and a modifying agent, and the thickness of the anti-ice-coagulation functional layer ranges from 3 cm to 6 cm. A dispersion medium of the hydrophobic material is a trimethoxypropylsilane deionized water solution, and a dispersion phase is one or two kinds of hydrophobic silicone oil substances of polytetrafluoroethylene and fluoroalkyl silane. The modifying agent is prepared by mixing nano-zinc oxide particles and a penetrating agent. An asphalt face layer is an OGFC pavement, and the thickness of the asphalt face layer is about 30 cm to 40 cm. The anti-ice-coagulation compound asphalt face layer structure is prepared in a layered construction manner, the epoxy bonding layer with the thickness ranging from 4 cm to 7 cm is poured to the body of the asphalt face layer, the anti-ice-coagulation functional layer is then smeared to the surface of the epoxy bonding layer, and therefore the asphalt pavement obtains the relatively good anti-ice-coagulation performance.

Description

technical field [0001] The invention belongs to the technical field of novel road surface design, and relates to a superhydrophobic anti-icing composite asphalt surface layer structure and a preparation method thereof. Background technique [0002] The development of the road transport industry plays a vital role in the economic development of our country. Statistics show that by the end of 2015, the mileage of expressways in operation had reached 123,000 kilometers, ranking first in the world for four consecutive years. During the "13th Five-Year Plan" period, the national expressway mileage will continue to increase, and by the end of 2020, it is expected to reach 169,000 kilometers. Our country has a vast territory, great differences in topography and landforms, and different climates in different regions. Road traffic is greatly affected by the natural environment, especially the icy road surface has brought a serious threat to the safety of people's lives and propertie...
