Embodiment Construction

[0052] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0053] The road asphalt is composed of the following components by weight: 20-35 parts of petroleum asphalt, 40-55 parts of coal tar pitch, 0.2-0.5 parts of zinc oxide, 3-5 parts of straw fiber and 1-2 parts of resin.

[0054] Using this component, by using petroleum asphalt and coal tar asphalt as main components, and properly adding zinc oxide, straw fiber and resin, etc., the road asphalt can withstand high and low temperature environments and has good performance.

[0055] The parts by weight of each component are as follows: 28 parts of petroleum pitch, 47 parts of coal tar pitch, 0.3 part of zinc oxide, 4 parts of straw fiber and 1 part of resin.

[0056] Coal tar pitch is medium temperature coal tar pitch.

Abstract

The invention provides road asphalt and a making technology thereof, aiming at solving the technical problems that the existing road asphalt is simpler in components, cannot adapt to high and low temperature environment, is poor in functionality, and the like. The road asphalt is prepared from the following components in parts by weight: 20-35 parts of petroleum asphalt, 40-55 parts of coal tar asphalt, 0.2-0.5 part of zinc oxide, 3-5 parts of straw fibers and 1-2 parts of resin. The road asphalt has the advantage of being good in service performance.

Description

technical field [0001] The invention relates to a road asphalt and a production process thereof. Background technique [0002] my country's transportation industry is developing rapidly, and road construction is advancing by leaps and bounds. At present, most of my country's road construction uses petroleum asphalt, and my country's petroleum asphalt production is limited, which is difficult to meet the needs of domestic road construction. In particular, the supply of high-quality petroleum asphalt is insufficient, and millions of high-quality petroleum asphalt are imported from abroad every year. Many changes have taken place in modern highways and roads, traffic flow and driving frequency have increased sharply, and the axle load of freight vehicles has continued to increase. Lanes and one-way driving are generally implemented. Flexibility and elasticity, that is, the ability to resist cracking at low temperatures; improve wear resistance and extend service life.
