Asphalt additive for cold repair of road surface

Abstract

The asphalt additive material for cold repair of road surface consists of: styrene-butadiene-styreene block copolymer 2-5 weight portions, petroleum resin 1-3 weight portions, terpene resin 1-3 weight portions, polyamide 0.3-0.7 weight portions, N-cyclohexyl-N'-phenyl-phenylenediamine 0.3-0.7 weight portions, mineral oil 1-3 weight portions, styrene 3-7 weight portions, diesel oil 3-7 weight portions and asphalt 70-90 weight portions. It is prepared through mixing the materials at 170- 200 deg.c via high speed stirring for mutual reaction. The present invention has reasonable preparation process, and the asphalt additive material for cold repair of road surface has simple application, long storage period, high repair quality, wide use, environment friendship and low cost.

Description

technical field

[0001] The invention relates to a road surface material in road and bridge engineering, in particular to a road surface cold-patch asphalt additive material. Background technique

[0002] With the continuous development of the transportation industry, the traffic volume is increasing day by day, and the resulting road surface damage is also accelerating. Repairing damaged pavement is an important part of pavement maintenance. In the past, most of the repair materials used hot-mix asphalt concrete. Due to the limitation of season and temperature, the damaged pavement could not be repaired in time at any time. As a result, the pavement cold patching material came into being. It broke through the constraints of hot-mix asphalt concrete due to construction conditions, and has been widely used in various domestic markets due to its simple operation, long-term storage, good repair quality, wide application, and environmental protection. It has been partially prom...
