Abstract

The invention relates to a modified asphalt pouring sealant used for roads. According to the invention, through tests upon SBS white carbon black compound modified asphalt basic performances, the influences of white carbon black with different dosages to SBS-modified asphalt are studied. As a result, with a white carbon black dosage of 3%, 5 DEG C ductility of SBS-modified asphalt is slightly reduced, and equivalent brittle point (T1.2) value is reduced. With carbon black dosage of 3%, SBS modified asphalt high-temperature performance and temperature susceptibility are improved.

Description

Technical field [0001] The invention is a pavement maintenance material, especially used for joint filling material of asphalt pavement and the like, and is an advanced technology in pavement maintenance materials. technical background [0002] At present, China's highways are developing rapidly, and the mileage of traffic is also increasing accordingly. The task of the road maintenance industry is very arduous, and the technology of pavement groove filling and joint filling is an important means in the maintenance industry. The potting adhesives used for filling joints emerge in endlessly. The potting adhesives used in the market now usually use modified asphalt polymer materials. At high temperatures, the potting adhesives may melt and flow, and at low temperatures, the potting adhesives may appear brittle And other phenomena, the anti-aging ability is not strong. In order to solve the above technical problems, it is necessary for us to develop a potting compound with mor...
