Abstract
The invention relates to the technical field of municipal construction, in particular to a material for maintaining highway pavement and a process thereof. The components and weight portions are 1000 stone, 10-20 mineral filler, 60-120 water, 110-130 modified emulsion asphalt and 0.4-1.2 additive. The material for maintaining highway pavement on the highway pavement is paved for 45 minutes natural drying. The invention largely shortens the time of maintenance for highway pavement (prior art needs 6 to 8 hours to pave the way for service to return, but the invention only needs 45 minutes to pave the way for service to return), lessens the negative impacts for highway maintenance operation, and adequately develops the use value of public resources. The invention produces not only certain economic benefit, but also good social benefit.
Description
technical field [0001] The invention relates to the technical field of municipal construction, in particular to a highway pavement maintenance material and a highway pavement maintenance method. Background technique [0002] At present, in the process of maintenance and construction of micro-surfacing of highway pavement at home and abroad, materials such as modified emulsified asphalt, stone, water, mineral fillers and other materials are often mixed and stirred in a certain proportion to form a mixture and then paved on the road surface. . In maintenance construction, due to temperature, climate and other reasons, the above-mentioned mixture will break demulsification too quickly, causing it to harden in the paving box and cannot flow out of the paving box smoothly on the road surface, and due to the mixture Due to the characteristics of the road, the mixture paved on the road surface cannot be condensed for a long time, which affects the smooth flow of the road.
