摘　　要：岩沥青是一种天然沥青改性剂,具有沥青混合料路用性能的特性。以"轮胎驱动式路面功能加速加载试验系统"作为试验平台,对不同掺量岩沥青的改性乳化沥青微表处混合料进行室内加速加载试验。通过模拟实际道路特点,研究微表处混合料抗滑性能变化规律,并定量评价岩沥青掺量对其路用性能的影响。研究成果对推动微表处技术的应用与发展具有重要意义。Rock asphalt is a natural asphalt modifier with the characteristic of improving the road performance of asphalt mixture. With the ＂ tire-driven acceleration loading test system of pavement functions＂ as the test platform,this paper carries out the indoor acceleration loading test for the mixture at micro-surfacing of modified emulsified asphalt with different contents of rock asphalt. By simulating the features of actual roads,the paper studies the change rules of skid resistance of the mixture at micro surface and quantitatively evaluates the influences of the contents of rock asphalt on its road performance.The results of research are significantly important for promoting application and development of micro surface technologies.
