摘要
通过对某国道旧路面状况评价及交通量调查,确定水泥稳定就地冷再生的再生厚度;并在配合比设计中添加不同规格的新料,分析其对混合料强度的影响.结果表明：当旧沥青路面材料骨料偏少时,掺加规格为10～20mm的新料可以有效提高再生混合料的强度.
The recycling depth of the cement stabilized cold recycling project was determined by means of the evaluation on the situation of existing pavement of a national highway and the survey of traffic load. New materials with different gradations were added to the mixture in order to study their impact on the strength. The results indicate that when the aggregate reclaimed from old pavement accounts for a small part, the strength of mixture could be improved by adding macadam with a dimension of 10-20 mm.
