AS 渗透养护剂对沥青混合料性能改善的试验分析
Experimental analysis on applying AS infiltration maintenance agent to performance improvement of asphalt mixture
摘要
Abstract
The AS infiltration maintenance agent is a new kind of inorganic and special mate-rial for preventive maintenance of asphalt pavement.It depends on the effects of infiltration and crystallization to form a unique three-dimensional reinforced network structure on the AC surface and in the AC micro fissures,then the pavement performances,such as high temperature and water stability etc.of asphalt pavement are improved.In order to research the improvement effects,the common asphalt mixture of SBS modified AC- 13C for sur-face layer is selected as the brushing matrix.Through the laboratory experiments,the com-parative analysis were conducted to the various pavement performances of AC-13C pre and post brushing AS agent,and its experimental section was also validated.The results show that the AS agent meets the technical requirements for infiltration film-forming waterproof coating.After brushing the AS agent,the impermeability,the bond strength and the wear resistance of SBS modified AC- 13C are improved significantly,all the high temperature stability,the low temperature crack resistance,the water stability,the aging resistance and the anti-corrosion ability of acid and alkali etc.get some improvements,but the skid resist-ance performance is impacted to a certain degree.Therefore,the AS agent can be applied to the preventive maintenance of asphalt pavement.关键词
