Construction Quality Control of Asphalt Pavement in High Cold and Rainy Climate Area
In the high cold and rainy area,the paving of asphalt surface is greatly affected by the environment,construction technology,materials and other factors,which leads to the formation of asphalt pavement quality dis-eases are different from common areas,mainly showing cracks,frost heave,rutting and spalling.Based on a typical project in Garze Tibetan Autonomous Prefecture,this paper focuses on the quality control measures of asphalt surface construction.According to the common diseases,the paper analyzes the underbearing layer,drainage,mix ratio,paving thickness,temperature and construction technology,and summarizes the applicable crack prevention and control,frost heave and spalling prevention and the appropriate mix ratio and construction control technology during the paving process.These measures not only speed up the construction progress,but also improve the con-struction quality.
