Abstract

The invention discloses a high viscosity modified asphalt formula suitable for a drainage asphalt pavement. The formula comprises the following components in percentage by weight: 70-85% of #70 matrix asphalt, 3-9% of an SBS modifier, 8-18% of rubber powder, 2-6% of terpene resin, 1-5% of diatomite, 6-15% of asphalt -based carbon fibers for spinning and 2-5% of a warm mixing agent. The high viscosity modified asphalt formula disclosed by the invention is reasonable in step and simple in formula. The viscosity, weather resistance and water stability of the asphalt are remarkably improved. The matrix asphalt is uniformly dispersed, is high in forming degree, is unlikely to age, and is low in sensitivity on environmental temperature.

Description

technical field [0001] The invention relates to a high-viscosity modified asphalt formula suitable for drainage asphalt pavement with reasonable process, energy saving and environmental protection and its modification process. Background technique [0002] SBS modified asphalt has good high temperature resistance, low temperature resistance, frost resistance, and vehicle withdrawal resistance. It is widely used in domestic high-grade highways, urban arterial roads and airport runways, such as: [0003] Chinese patent application number: 201310190437.1 discloses a SBS modified asphalt and its preparation method, the SBS modified asphalt includes base asphalt and additives, the additives include SBS modifier and stabilizer, the base asphalt is composed of Obtained by straight distillation of Swiss oil and Boscan oil, wherein the weight ratio of Marui oil and Boscan oil is 100:0, 90:10, 85:15, 75:25 or 50:50. [0004] Chinese patent application number: 201510608456.0, disclose...
