Research on Construction Technology of Asphalt Sand Waterproof Stress Absorbing Layers
Based on the status quo that the demand for long-lasting and durable asphalt pavements increases,and the traditional semi-rigid base stress absorbing layers are difficult to meet the structural performance of perpetual pavements,for asphalt sand waterproof stress absorbing layers,the mix proportion is designed,and construction process is studied to determine the technical requirements,mix proportion and construction process of the materials.The results have engineering reference values for the reasonable application of asphalt sand wa-terproof stress absorbing layers.
