通过对黑龙江省某高速公路小修工程原有路面上面层的AC-16型沥青混合料进行就地热再生配合比设计。结合现场取样、室内试验数据,按照内插法确定了混合料中再生剂掺配比例,并采用马歇尔设计方法进行再生混合料的配合比设计。最后通过现场对再生混合料的路用性能进行了验证,其结果综合表明该设计的再生混合料高温稳定性和水稳定性均能满足要求。 Through the on-site thermal regeneration mix design of the AC-16 asphalt mixture above the original pavement of a highway minor repair project in Heilongjiang Province. Combined with field sampling and laboratory test data, the proportion of regenerant in the mixture was determined according to interpolation method, and the mix design of recycled mixture was designed by Marshall design method. Finally, the road performance of the recycled mixture was verified by on-site test. The results show that the recycled mixture of the design can meet the requirements of high temperature stability and water stability.
