Problems solved by technology

The above two materials must be used at one time, and cannot be used next time. If it rains during construction, the materials cannot be used after being exposed to rain.
In addition, emulsified asphalt materials cannot be used for large-scale construction and maintenance of high-grade road surfaces
Furthermore, hot-mix asphalt materials and emulsified asphalt materials are only suitable for construction in seasons with high temperatures, while in winter with low temperatures, construction is very inconvenient or even impossible.
Therefore, road maintenance is restricted in many ways

Abstract

The present invention relates to a kind of asphalt road cold repairing material. It is prepared with ehavy oil, C5 or C9 petroleum resin, C1-C10 solvent oil, styrene-butadiene rubber, diesel oil or kerosene or gasoline, thermoplastic styrene-butadiene rubber, naphthenic oil, RC-10 mineral oil and road petroleum asphalt. The preparation process includes preparing prepolymer A with heavy oil and petroleum resin; preparing prepolymer B with solvent oil and styrene-butadiene rubber; preparing prepolymer C with diesel oil or kerosene or gasoline, thermoplastic styrene-butadiene rubber and naphthenic oil; preparing cold repairing asphalt additive with prepolymer A, prepolymer B, prepolymer C and RC-10 mineral oil; and adding road petroleum asphalt.

Description

technical field [0001] The invention relates to a road patching material, in particular to an asphalt binder for cold construction asphalt pavement materials and a manufacturing method of the asphalt binder. Background technique [0002] The existing road materials for asphalt roads mainly include hot mix asphalt mixture and emulsified asphalt mixture. Hot mix asphalt mixture is made by frying and mixing petroleum asphalt, aggregate, powder, etc. in a certain proportion with asphalt mixing equipment in the factory. Then transport the hot hot asphalt mixture to the construction site in time to repair the asphalt road surface. But the whole process needs to be closed to traffic. Emulsified asphalt mixture is made by mixing emulsified asphalt, aggregate, powder, etc. in a certain proportion. After the emulsified asphalt mixture is used for road repair construction, it must wait for the emulsion in the emulsified asphalt mixture to break. It usually takes 3 to 5 days to open ...
