The AS infiltration maintenance agent is a new kind of inorganic and special material 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 surface and in the fine cracks of asphalt concrete,then the pavement performances such as high temperature and water stability etc.of asphalt pavement are improved.In order to research its improvement effects,the common asphalt mixture of SBS modified AC-13C for surface layer is selected as the brushing matrix.Through the laboratory testing,the comparative analysis were conducted to various pavement performances of AC-13C before and after the AS agent brushing,and the validation of field test road section was also conducted.The results show that the AS agent meets the technical requirements of infiltration film-forming waterproof coating.After the AS agent brushing,the impermeability,bond strength and wear resistance of SBS modified AC-13C are improved significantly,all the high temperature stability,low temperature crack resistance,water stability,aging resistance and corrosion resistance capability of acid and alkali etc.are gotten some improvements,but the skid resistance performance is impacted to a certain.Therefore,the AS agent can be applied to the preventive maintenance of asphalt pavement.
