Asphalt milling material is a waste material that is cut down from the surface layer of the old asphalt pavement by milling machine in the process of road maintenance or reconstruction, mainly composed of asphalt, stone and additives. Its treatment and reuse are of great significance to resource recycling and environmental protection.
Asphalt milling material
Asphalt milling material has a complex composition, containing asphalt, aggregate, impurities and moisture, high hardness and uneven particle size. Needs to be crushed into uniform particles in order to meet the proportioning standards of recycled asphalt mixture, and at the same time to avoid excessive crushing to destroy the gradation.
Recommended crushing equipment double-toothed roll crusher, double-toothed roll crusher is the ideal equipment to deal with asphalt milling planing material, its advantages are as follows:
The double-toothed roll crusher crushes the asphalt by squeezing and shearing with two relatively rotating rollers. Quickly crushing the large milling material with even and adjustable particle size. The crusher’s rollers are made of high-strength alloy rollers. Which can withstand the abrasion of hard aggregates and prolong the life of the equipment. Low energy consumption, low dust and noise, in line with the requirements of green production. The double-tooth roll crusher can handle cold/hot milling material, and the particle size can be controlled by adjusting the pitch of rollers to reduce the phenomenon of over-crushing.
The crushed milling material can be used directly for new road surfacing, saving raw material costs. It reduces waste to landfill, lowers carbon emissions, and promotes sustainable development of road construction. The use of crushing and screening integrated production line (including double-toothed roll crusher) can quickly process a large amount of material and shorten the construction period.
The recycling of asphalt milling material requires a combination of highly efficient equipment (such as double-toothed roll crushers), accurate testing methods and scientific proportioning design to achieve the goals of resource recycling and environmental protection.
Future technology will focus more on flexible crushing and intelligent production to promote the sustainable development of the road maintenance industry.
