Abstract

The invention provides a foamed asphalt containing sodium hypochlorite oxidized waste tire rubber powder, and relates to the field of pavement materials. The foamed asphalt is prepared from, by weight, 40 to 60 parts of SBS modified asphalt, 10 to 15 parts of a zeolite powder / ZnO compound, 20 to 30 parts of ordinary Portland cement, 12 to 18 parts of the sodium hypochlorite oxidized waste tire rubber powder, 10 to 20 parts of fly ash, 1 to 5 parts of a sulfinic acid lactone type foaming agent, 0.1 to 1 part of glycidyl methacrylate, 5 to 10 parts of dimethyl phthalate, 1 to 3 parts of hydroxypropyl methylcellulose, 20 to 30 parts of basalt stone, 50 to 60 parts of aggregate, 2 to 4 parts of pentaerythritol, 5 to 10 parts of reinforced fibers and 12 to 15 parts of a binder. The prepared foamed asphalt is excellent in mechanical properties and high in water stability, the foamed asphalt still has high cohesive force under the action of freeze-thaw cycle, the splitting strength is reducedwithin an acceptable range, and the foamed asphalt is high in rut resistance and suitable for large-scale application.

Description

technical field [0001] The invention relates to the field of pavement materials, in particular to foamed asphalt containing sodium hypochlorite oxidized waste tire rubber powder. Background technique [0002] At present, in the process of road construction in our country, asphalt has been widely used, the most common of which is SBS modified asphalt, but research shows that: polymer modified asphalt requires large investment in production and process equipment, such as special Shearing equipment and more energy consumption, etc., require continuous heating and stirring in transportation and storage to prevent the delamination and segregation of the modifier and asphalt. These shortcomings limit the polymer modified asphalt to a certain extent. Applications. [0003] Natural asphalt, like base asphalt, is a derivative of petroleum. It has a very good compatibility with base asphalt, so there is no segregation when the two are mixed. Natural asphalt has no special requirement...
