Embodiment 1

[0024] First take 3000g of rock asphalt with a particle size of 400 mesh, 4500g of recycled polyethylene (RPE, waste film with a side length or radial dimension of about 10mm) and 2500g of diatomite with a particle size of 400 mesh. Weigh and add quantitatively to the screw extruder for blending and extrusion (the processing extrusion temperature is 160° C.), to form a strip-shaped semi-finished product. Then through water cooling (water temperature is lower than 20°C), wheel cutter slitting and granulation (particle size 3-4mm), and drying in a drying device for one hour (temperature 80°C), the novel anti-bacterial agent of the present invention can be obtained. Finished rutting agent.

Embodiment 2

[0026] First take 2500g of 400-mesh rock asphalt and 3000g of diatomite with similar particle size, and 4500g of low-density polyethylene (LDPE) (particle size is less than 1mm), after mixing (the method is the same as above), and metering into the screw extruder for co-extrusion (processing The extrusion temperature is 150° C.) to form a strip-shaped semi-finished product. Then through water cooling (water temperature is lower than 20°C), wheel cutter slitting and granulation (particle size 3-4mm), and drying in a drying device for one hour (temperature 80°C), the novel anti-bacterial agent of the present invention can be obtained. Finished rutting agent.

Embodiment 3

[0028] Raw material adopts rock pitch 3000g, polyvinyl chloride (PVC) 5000g and diatomite 2000g, and other methods and process parameters are the same as embodiment 2.

Abstract

The invention relates to novel anti-rutting agent and a production method thereof, wherein the novel anti-rutting agent comprises rock asphalt and polymer and is characterized by also comprising diatomite. The parts by weight of the rock asphalt, the polymer and the diatomite are respectively 25-35 parts, 40-50 parts and 20-30 parts. The method comprises the following steps: the rock asphalt, the polymer and the diatomite are crushed, weighed according to proportions, put into a mixer and mixed; and then, the mixing materials are extruded into strips by a screw extruder and cut into particles after being cooled; and finally, the particles are dried. The invention has the advantages of safe, simple and convenient use, even dispersion, anti-rutting performance at the higher temperature, anti-cracking performance at the lower temperature, low cost and higher cost performance.

Description

technical field [0001] The invention relates to a novel anti-rutting agent, which is mainly used for mixing in the surface layer of asphalt pavement to improve the high-temperature stability of the asphalt mixture of the surface layer and the anti-rutting ability of the road surface. Background technique [0002] Rutting has always been one of the main diseases of asphalt pavement under heavy load and channelized traffic conditions. Severe ruts seriously endanger driving safety, and other types of diseases, such as oil flooding and cracking, are often accompanied by the formation of ruts. If maintenance is not carried out in time, the service life of the pavement will be greatly shortened. However, it will cost a lot of maintenance funds to control the rutting disease. Practice has proved that the use of asphalt mixture with strong anti-rutting ability in new construction or overhaul projects can avoid rutting disease on asphalt pavement to the greatest extent, and will gr...
