Composite road surface intensifier and production method thereof

Abstract

The invention relates to a composite road surface intensifier and a production method thereof. The composite road surface intensifier comprises the following components in part by weight: 29 to 34 parts of PE, 10 to 16 parts of rock asphalt, 13 to 21 parts of rubber powder, 2 to 4 parts of diatomite, 4 to 8 parts of silicon dioxide and 27 to 37 parts of protolignin. The production method comprises the following steps of: mixing and pulverizing the granular PE and the rubber powder into a dualistic mixture, wherein the temperature is lower than 60 DEG C; fully mixing the dualistic mixture, the rock asphalt, the diatomite, the silicon dioxide and the protolignin to form a multiplex mixture; and extruding the multiplex mixture into irregular particles with particle diameter of between 3 and 6 mm by using a plastic particle machine, wherein the temperature is lower than 120 DEG C during extrusion. The composite road surface intensifier has the advantages that: the asphalt mixture on the SMA road surface has simple field production and operation, namely a granular formulation is thrown into a mixture stirrer, so that the performance of the original SMA mixture is kept, and the anti-tracking capacity is stronger and the cost is lower.

Description

Technical field [0001] The invention involves a composite pavement enhancer and its production method. The composite pavement enhancer is mainly used to produce mixture of highways, airport runways and heavy loading traffic road surfaces. Background technique [0002] The existing pavement enhancer agent and modified the matrix asphalt into new modified asphalt need to be used to use a mixed process with the matrix asphalt to form a new modified asphalt.Then mix the modified asphalt with stone and wood fiber to produce an English abbreviation of SMA ("Stone Matrix Asphard", Chinese mixture in ChineseThe performance of asphalt hybrids has been greatly improved. It is often used in highways, airport runways and heavy loading roads.However, this SMA mixed material production process needs to be finally mixed with wood fibers to avoid making PE and rock asphalt into liquid in the production process of enhanced agents and absorbed by wood fibers, thereby reducing the role of wood fib...
