Abstract

The invention relates to a benzyl benzoate waste mixed modified asphalt. The modified asphalt is prepared from the following raw materials by weight: 40-60 parts of petroleum asphalt, 20-40 parts of coal pitch, 40-80 parts of benzyl benzoate waste, 15-30 parts of ethylene glycol monomethyl ether, 10-15 parts of ethylene glycol, 2-5 parts of alkylphenol polyoxyethylene ether, 1-3 parts of aluminum isopropoxide, and 1-3 parts of zinc stannate. The method provided by the invention has the advantages that: 1. the process is simple, the equipment requirement is low, the method can realize large-scale production of modified asphalt, and the modified asphalt finished product can meet the requirements of national regulations and can be used for asphalt road pavement construction; 2. the method also can reduce the content of polycyclic aromatic hydrocarbon 3, 4-benzopyrene (Bap) in mixed asphalt; and 3. more importantly, benzyl benzoate waste is utilized to replace expensive raw materials to serve as the modifier.

Description

technical field

[0001] The invention belongs to the technical field of resource recycling and asphalt materials, and in particular relates to a kind of benzyl benzoate waste mixed modified asphalt. Background technique

[0002] In recent years, with the rapid development of my country's transportation industry, road construction has advanced by leaps and bounds, requiring a large amount of road asphalt. Most road asphalt uses petroleum asphalt with good stability and plasticity. However, petroleum resources are becoming increasingly scarce, and international crude oil prices continue to rise, so the supply of petroleum asphalt is also tight. Compared with petroleum asphalt, coal tar pitch has high aromaticity and high polarity, and has good compatibility and affinity with sand and gravel materials, and coal tar pitch pavement is anti-deformation, anti-wear, and driving safety is outstanding. Therefore, if coal tar pitch and petroleum pitch are mixed and used, it can not onl...
