摘　　要：鉴于目前常规雾封层和微表处等路面预防性养护措施存在的诸多问题,基于改善渗透性和浅表固化的角度出发,研究新型路面封层材料。通过标准沥青黏度试验、沥青混合料贯入试验和室内路面表面功能加速加载试验评价,研究结果表明:新型封层在渗透性、路面浅表固化和抗表面功能衰减等方面都表现出明显的优势,可以作为更新换代的封层形式用于路面预防性养护。In view of the problems existing in the pavement preventive maintenance treatments, such as the conventional fog seal and micro-surfacing techniques, from the consideration of improving permeability and surface solidification, a new type of pavement seal coating technology has been developed in this study. Using the standard asphalt viscosity test, the penetration test of asphalt mixture and the indoor pavement surface function accelerated loading test, the performances of the new seal are evaluated, and the results indicate obvious advantages in respect of permeability, pavement surface solidification as well as deterioration resistance of the pavement functional performances. The new seal is proved to be an upgrade treatment used in the pavement preventive maintenance.
