Abstract
A cold repair additive for road with asphalt pavement is prepaired from heavy oil, C5 or C9 petroleum resin, C1-C10 solvent oil, butadiene-styrene rubber, diesel oil or kerosene or gasoline, thermoplastic butadiene-styrene rubber, naphthenic oil, and mineral oil RC-10 through preparing three prepolymers, and preparing said additive. Its advantages are easy application and no environmental pollution.
Description
Technical field
The present invention relates to the patching material of road, the additive of particularly cold construction asphalt pavement material and the manufacture method of additive.
Background technology
The pavement material that existing asphalt roads is used mainly contains two kinds of hot-mix asphalt mixture and Emulsified Asphalt Mixture.Hot-mix asphalt mixture is with petroleum pitch, aggregate, powder etc. by a certain percentage, fries to mix with asphalt mix equipment in factory and makes.The timely then hot-mix asphalt mixture with heat is transported to the working-yard, repairs the asphalt roads road surface.But whole process all needs close traffic.Emulsified Asphalt Mixture is that emulsified bitumen, aggregate, powder etc. are mixed and made into Emulsified Asphalt Mixture by a certain percentage, after Emulsified Asphalt Mixture is used to repair road construction, after must waiting for the emulsion breaking in the Emulsified Asphalt Mixture, the ability open to traffic generally needs to wait for 3～5 days.More than two kinds of materials all must disposable using, can not use next time again, in the construction in case of raining, just can not use after material is caught in the rain.Emulsified bituminous materials can not be used for the maintenance of large-area construction and high grade pavement in addition.Moreover hot mix asphalt material and emulsified bituminous materials only are suitable for temperature construction in higher season, and in temperature lower winter, just very inconvenient during construction, even can not construct.Therefore, the maintenance to road just is subjected to many-sided restriction.
Summary of the invention
In view of above-mentioned, the object of the present invention is to provide a kind of make easy construction, quick, the close traffic not of constructing, free from environmental pollution, be suitable for various geography and temperature condition, the cold repairing additive for road and the manufacture method thereof of the asphalt pavement material that can store.
