| 摘 要： | 通过一系列的室内外试验,对某种沥青还原剂(TL-2000)在还原老化沥青性能、铺洒后对路面防渗水性能改善及对防滑性能的影响进行了初步研究认证。得出结论:掺加一定剂量的沥青还原剂,对老化后的沥青可起到一定的软化作用,铺洒后对原路面的防渗水性能有明显改善,虽对旧路面的抗滑性能产生一定的负面影响,但可在短期内快速自行恢复到可接受水平。

| Abstract: | Based on a series of indoor and outdoor tests,this paper studied one asphalt rejuvenation agent's effect on aged asphalt rejuvenation, pavement permeability resistance,and skid resistance.The results show that a certain dose of rejuvenation agent can soften aged asphalt,improve pavement's impermeability significantly,but it has negative impact on the old-road's anti-skid performance, however it may self-recover to a acceptable level in a short time. |
