高性能半柔性路面材料设计及性能研究

Research on Design and Performance of Semi-flexible Asphalt Mixture

文章采用体积法对基体沥青混合料进行配合比设计,通过肯塔堡飞散试验和谢伦堡沥青析漏试验确定最佳沥青用量,并对水泥胶浆进行配合比设计,最后结合高温稳定性、水稳定性能、低温性能以及耐油蚀性能等试验对半柔性路面材料的路用性能进行评价。研究结果表明,半柔性路面具有较好的高低温稳定性、水稳定性和耐油蚀性能。

In this paper, the base asphalt mixture is designed by means of volumetric method. The optimal asphalt dosage is determined by evolution leakage and scattering experiments. The mixture design of cement slurry is conducted. And the properties of high and low temperature stability, water resistance and fuel resistance of semi-flexible material are evaluated. The results show that the semi-flexible asphalt mixture has excellent pavement performance.
