Abstract
The invention discloses high-molecular polymerasphalt for road crack repair, a manufacturing method and a crack-bonding belt. The high-molecular polymerasphalt for road crack repair comprises the following components by mass: 80-85% of AH-70A road petroleumasphalt; 6-8% of liquid star-shaped SBS asphalt modifier; 1-2% of diatomite; 0.3%-1.0% of polyacrylates; 0.8-1.2% of liquid rosin; 1.5-2.5% of C-5 petroleum resin; 0.9-1.5% of wood fiber; 2-3.5% of calciumhydroxide; 0.5-2.0% of asphalt anti-stripping agents. The high-molecular polymer asphalt of the invention is applicable to the treatment of various cracks of highways and urban roads including reflection cracks, and is also applicable to crack treatment before construction of seal coat overlay and the like; the crack treatment does not require heating, and the asphalt is self-adhered; the crack treatment is environment-friendly, requires no special equipment, no crack enlargement, and the asphalt can be stored at normal temperature.
Description
technical field [0001] The invention relates to road asphalt, in particular to a high molecular polymer asphalt for repairing road cracks, a production method and a joint tape. Background technique [0002] Highways and urban road traffic are important components of cities. They are the link between cities and organically connect various functions such as production and life in cities. They are important conditions for the survival and development of cities. The guarantor and the circulation of goods are the key to maintaining the vitality of the city. [0003] At present, highways and urban roads mainly include asphalt concrete and cement concrete, of which asphalt concrete roads occupy a considerable proportion. Different from other engineering facilities, asphalt concrete roads generally suffer damages of varying degrees and scopes shortly after they are opened to traffic. If these minor damages can be timely preventive maintenance at the beginning, the expansion trend a...
