摘　　要：赛欧铺是一种硫磺沥青改性剂.在AC-16C级配沥青混合料掺入18%的赛欧铺,通过室内试验对赛欧铺改性沥青混合料的高温稳定性和水稳定性进行研究;并对比了赛欧铺改性沥青混合料不养生和养生7天以及14天的力学性能的差异.试验结果表明:赛欧铺改性沥青混合料的高温稳定性得到了较大的改善,其水稳定性没有太明显的提高,但是,抗剥落剂的增加可在提高AC-16C混合料的高温稳定性的同时提高其水稳定性.养生14天相较于养生7天以及不养生,对加赛欧普的AC-16C混合料的高温稳定性和水稳定性有较大的提高,尤其是高温稳定性,因此,养生对于加赛欧普的AC-16C混合料至关重要.Thiopave is a kind of sulfur asphalt modifier.AC-16C hot-mix asphalt mixed with 18%Thiopave modifier was taken for the laboratory test to investigate the high temperature stability and water stability.The performance of this asphalt concrete was also tested after 7 days and 14 days curing on normal environment.The experimental results show that the high temperature stability of Thiopave asphalt mixture is improved greatly,but its water stability is not improved obviously; the addition of antistripping agent in AC-16C increases the high temperature stability and the water stability at the same time;curing 14 days compared with curing 7 days and without maintenance,the high temperature stability and water stability of AC-16C mixture has a great increase,therefore,the maintenance for adding Thiopave modifier AC-16C mixture is very important.
