采用高模量沥青混合料(High Modulus Asphalt Concrete,简称HMAC)的设计理念进行旧料高掺量回收利用,将路面性能提升与大比例利用路面旧料有效地结合起来,对再生混合料进行室内力学性能及路用性能试验,研究发现高掺量旧料的加入未对HMAC的性能产生消极影响,掺加旧料的HMAC混合料的不低于甚至高于未掺加旧料的HMAC的路用性能。经性能试验表明,通过控制回收材料的均匀性并利用新添加沥青足够的流变性,可获得高掺量及高性能的再生沥青混合料。
High-modulus asphalt mixture (High Modulus Asphalt Concrete, referred to as HMAC) design concept of high-volume recycling of used materials, the road performance improvement and the large proportion of the use of the road surface old material effectively combine the recycled mixture for indoor Mechanical properties and road performance tests, the study found that the addition of high-volume feedstock did not have a negative impact on the performance of HMAC HMAC mix with the old material not less than or even higher than the unadulterated HMAC road With performance. The performance tests show that by controlling the uniformity of recycled materials and the use of new addition of sufficient rheological rheology asphalt, high volume and high performance recycled asphalt mixture can be obtained.
