Study On Skid Resistance And Drainage Technology Of The Highway And Runway Asphalt Pavement

Based on the Zheng Min highway project, which is concurrently military airport runway,it is required that the highway and runway is bearing the high traffic load and aircraft load ofemergency, while it is required that pavement has good performance of durability and skidresistance. However, it is lack of mature technology, related technology research anddevelopment is urgent and necessary.Skid resistance and drainage mechanism of the highway and runway asphalt pavementwas analyzed. While the cooling mechanism and effect of warm asphalt mixture of thehighway and runway was evaluated and researched, highway runway asphalt mixturetechnical specification was advanced, the AC, SMA, OGFC and epoxy asphalt mixture waschoosed, while the use of warm asphalt mixture technology was used on the highway andrunway asphalt pavement.First, this paper studies the main technical indicators of the highway and runwaypavement material, warm asphalt mixture mixing and compaction temperature is20~30degrees lower than hot asphalt mixture, warm asphalt mixture compaction temperature is140degree. Design of the mix proportion and their performances of warm and hot AC-13C,SMA-13, OGFC-13and epoxy asphalt mixture were researched and compared, includinghigh-temperature stability, anti-water damage ability, low-temperatur and fatigue resistance.Second, durability of the highway and runway asphalt mixture was evaluated, includinganti-water damage ability, anti-aging performance and fatigue resistance."Load simulation ofheaving and thawing circulation" test to the highway and runway asphalt mixture was putforward, to evaluate the water stability performance.Asphalt mixture anti slide performanceinterior testing is in on the wheel rut test sample, using friction coefficient and depth ofcharacterization.Skid resistance performance of highway and runway asphalt pavement testmethod was put forward to evaluate.Finally, the melting snow technology of highway and runway was studied, including saltmelting snow and lulimei.Rate of melting snow test was put forward, which is suitable forthe highway and runway pavement.
