Novel asphalt for water penetrating pavement and preparation method thereof

The invention discloses novel asphalt for a water penetrating pavement and a preparation method thereof. The asphalt is composed of the following components in parts by weight: 6-8 parts of a granular SBS modifier, 3-5 parts of resin, 3-5 parts of an anti-ageing agent, 0.1-2 parts of a stabilizer and the balance of matrix asphalt, totaling 100 parts. The high-viscosity modified asphalt disclosed by the invention is low in cost of material. Compared with an existing high-viscosity modified material, the compound material is low in price, can achieve the same effect, and has relatively high market competitiveness. The detecting index result of the high-viscosity modified asphalt fully meets the standards of the Ministry of Communications and the Ministry of Housing and Urban-Rural Development. 本发明公开了种渗水路面新型沥青及其制备方法，由下列重量份数的各组份组成：颗粒状SBS改性剂6-8份，树脂3-5份，抗老化剂3-5份，稳定剂0.1-2份，余量加基质沥至100份。本发明高粘改性沥青的材料成本低，采用的复配材料与市场上现成的高粘改性性相比，价格便宜，可能达到相同的效果，具有较高的市场竞争力，本发明的高粘改性沥青检测的指标结果完全符合交通部和住建部的标准。
