岩沥青微表处路用性能加速加载试验研究

岩沥青是一种天然沥青改性剂，它具有改善路面的路用性能的特性。以“轮胎驱动式路面功能加速加载试验系统”作为试验平台，添加不同含量的岩沥青改性乳化沥青对微表处混合料进行改良，并进行室内加速加载试验。通过模拟实际道路特点，分析微表处混合料路用性能变化规律，并定量评价岩沥青的含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。

Accelerated Loading Experimental Research on Road Performance at Micro-surfacing of Rock Asphalt

Rock asphalt is a modifier of natural asphalt and has the property of improving the road performance of pavement. With ＂tyre drive type pavement function accelerated loading test system＂ as test platform, this paper improves mixture at micro-surfacing by adding modified emulsified asphalt of different contents in rock asphalt and carries out indoor accelerated loading test. By simulating actual road features, this paper studies change law of road performance of mixture at micro- surfacing, and quantitatively evaluates influences of the contents of rock asphalt on its road performance. The research results are significant for promoting application and development of micro-surfacing technology.
