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 a production process of road asphalt, aiming at solving the technical problems that the existing road asphalt is simpler in composition, cannot adapt to high and low temperatureenvironments, is poor in functionality, and the like. The production process of the road asphalt comprises the following steps: a. cutting the straw by using a common cutting machine, wherein the cutting length is 7 mm; b. soaking the cut straw into a solution for 3 hours, and drying until the water content of the straw is 45%; c. adding the straw obtained in the step b into pulping equipment forscattering so as to obtain slurry, wherein the pulping time is 15 min; d. dehydrating, drying and opening the slurry by using processing equipment so as to obtain straw fibers; e. heating and meltingpetroleum asphalt at the temperature of 190 DEG C, then sequentially adding coal tar asphalt, zinc oxide, the straw fibers and resin, raising the heating temperature to 220 DEG C, and stirring by using an ordinary disperser for 14min at a speed of 1800 r / min. The production has the advantage of being simple and convenient to operate.

Description

technical field [0001] The invention relates to a production process of road asphalt. 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. [0003] After sea...
