Problems solved by technology

[0002] Pavement cracks are one of the main diseases of our country’s highways. In my country, the traditional pavement repair materials mostly use ordinary modified asphalt and ordinary joint glue. Heating with gas and direct heating with some wood fires wastes a lot of energy and pollutes the air

Abstract

The invention discloses an energy-saving pavement crack repairing material and a preparation method thereof. The repairing material contains the following components by weight percent: 3% to 16% of melt temperature dropping agent; preferably, the repairing material contains 5% to 15% of melt temperature dropping agent, wherein the softening point of the melt temperature dropping agent is not lower than 110 DEG C; the melt temperature dropping agent is preferably selected from microfine wax, paraffin wax, polyethylene wax or polypropylene wax (APAO (Amorphous Poly Alpha Olefin) wax); and the softening point of the melt temperature dropping agent is preferably greater than 115 DEG C. The repairing material is good in low-temperature crack resistance, high-temperature stability, interface bonding force and aging resistance, thereby being suitable for the repairing of pouring cracks in majority of cold areas in China. According to the repairing material, the melt temperature dropping agent is adopted, so that the melt temperature is greatly decreased; the heating time is shortened; the heating construction is convenient to carry out; and the energy consumption is reduced, i.e., the pollution to the atmosphere, which is generated by the energy consumption, is reduced. The preparation method is simple and easy, and convenient for mass production.

Description

【Technical field】 [0001] The invention relates to an energy-saving pavement crack repair material and a preparation method thereof. 【Background technique】 [0002] Pavement cracks are one of the main diseases of our country’s highways. In my country, the traditional pavement repair materials mostly use ordinary modified asphalt and ordinary joint glue. Gas heating, and some firewood direct heating, waste a lot of energy, but also pollute the air. 【Content of invention】 [0003] The purpose of the present invention is to overcome the defects of the prior art, and provide a product with superior performance, low melting temperature, capable of melting at 140-150°C, and excellent low-temperature crack resistance, high-temperature stability, interface adhesion, and aging resistance. The energy-saving pavement crack repair material is suitable for the repair of cracks in asphalt or cement concrete pavement in most parts of my country. [0004] Another object of the present inve...
