Anti-freezing environment-friendly diluted asphalt and preparation method thereof

Abstract

The invention discloses anti-freezing environment-friendly diluted asphalt and a preparation method thereof. The anti-freezing environment-friendly diluted asphalt is prepared from the following raw materials in parts by weight: 50 to 80 parts of petroleum asphalt, 12 to 35 parts of biological asphalt, 10 to 26 parts of a modifier, 3 to 12 parts of a stabilizer, 25 to 58 parts of a diluent, 14 to25 parts of an inorganic filler calcium carbonate, 14 to 25 parts of glass fibers, 6 to 20 parts of a hydrophobic anti-freezing agent and 8 to 21 parts of shale ceramsite. The anti-freezing environment-friendly diluted asphalt of the invention solves the problems of weak high-temperature performance and strong temperature sensitivity of existing biological asphalt, high price of traditional road asphalt and the like in the prior art, has excellent high / low temperature resistance, skid resistance, wear resistance and aging resistance, does not flow at high temperature, has improved flexibilityat low temperature and favorable ductility, and can effectively overcome the problem that traditional diluted asphalt is easily limited by seasons, weather and temperature in the construction process.

Description

technical field [0001] The invention relates to the technical field of asphalt for road surface maintenance, in particular to an anti-icing environment-friendly diluted asphalt and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy and the continuous increase of traffic volume, the asphalt pavement has been subjected to more and more severe tests. During the long-term use of asphalt pavement, it is affected by various factors such as vehicle axle load, temperature difference between day and night, rain erosion, asphalt aging, etc., and various diseases such as potholes, washboards, ruts, and cracks often appear. These diseases on the pavement will affect the normal traffic of the road, reduce the service level of the asphalt pavement, and even cause traffic accidents in severe cases. Therefore, timely treatment of road surface diseases is necessary. In the prior art, the maintenance of the fog seal layer is genera...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the above-mentioned deficiencies, and provide an anti-icing environmentally friendly diluted asphalt, which solves the problems of weak high-temperature performance, strong temperature sensitivity and high price of traditional road asphalt in the existing biological asphalt, and has excellent Excellent high and low temperature resistance, skid resistance, wear resistance and aging resistance, no flow at high temperature, improved flexibility at low temperature, and good ductility of asphalt, which can effectively overcome the vulnerability of traditional diluted asphalt during construction seasons, weather, and temperature restrictions; in addition, the present invention also provides a preparation method of anti-icing environment-friendly dilute asphalt

[0005] Through the mixed modification of petroleum asphalt and bio-asphalt, the problems of weak high-temperature performance, strong temperature sensitivity and high price of traditional road asphalt in the existing bio-asphalt are solved; through the modification of inorganic filler calcium carbonate and glass fiber Asphalt, which significantly improves the high and low temperature resistance and aging resistance of asphalt, does not flow at high temperature, improves flexibility at low temperature, and at the same time makes the asphalt have good ductility, which can effectively overcome the traditional dilute asphalt during construction. Problems with weather and temperature restrictions
