沥青路面就地热再生中一般添加再生剂来对老化沥青进行中再生。本文在室内通过老化沥青的再生实验和再生混合料的车辙实验及动态蠕变实验,对再生剂对于再生混合料的高温抗车辙性能的影响展开研究。结果表明,老化沥青再生后软化点和车辙因子下降,再生混合料的抗车辙性能随再生剂用量的增大而降低。因此在进行再生混合料设计时,因严格控制再生剂的用量以保证再生混合料的高温性能。 Asphalt Pavement In-situ thermal regeneration is normally added with regenerant to regenerate the aged asphalt. In this paper, through the regeneration experiment of aged asphalt and the rutting experiment and dynamic creep experiment of recycled mixture, the influence of regenerant on the high temperature rutting resistance of recycled mixture was studied. The results show that the softening point and rutting factor of aged asphalt are decreased after regeneration, and the rutting resistance of recycled mixture decreases with the increase of the amount of regenerant. Therefore, the design of recycled mixture, due to strict control of the amount of regenerant to ensure that the high temperature performance of recycled mixture.
