Embodiment 1

[0024] First take 5000g of rock asphalt with 400 mesh size, recycle 15000g of polyethylene (RPE, waste film with side length or radial size about 10mm), 20,000g of diatomaceous earth with 400 mesh size and 60,000g of rubber powder, and mix them in the mixer at room temperature. ,Use electronic metering to add to the screw extruder for blending and extrusion (processing and extrusion temperature is 160°C) to form a strip-shaped semi-finished product. Then through water cooling (the water temperature is lower than 20℃), the wheel cutter is divided and granulated (particle size is 3~4mm), and it is dried in a drying device for one hour (temperature 80℃) to obtain the noise reduction of the present invention Finished anti-tracking agent.

Embodiment 2

[0026] First take 10000g of 400 mesh rock asphalt and 25000g of diatomaceous earth of similar particle size, as well as 20000g of low-density polyethylene (LDPE) (with a particle size of less than 1mm), and 65000g of rubber powder of about 60 mesh. Blending and extruding out of the machine (processing and extrusion temperature is 140°C) to form a semi-finished product in strip shape. Then through water cooling (water temperature lower than 20 ℃), wheel cutter slitting and granulation (particle size 3 ~ 4mm), and drying in a drying device for one hour (temperature 80 ℃), that is, the new type of resistance of the present invention is obtained. Finished rutting agent.

Embodiment 3

[0028] The raw materials used rock asphalt 14000g, polyvinyl chloride (PVC) 30,000g, diatomaceous earth 30,000g and rubber powder 70,000g, the particle size is the same or similar to the above-mentioned embodiment, and the process flow and process parameters are the same as in embodiment 2.

Abstract

The invention provides a noise-reducing and rut-resisting agent and a production method thereof. The agent comprises rock asphalt, polymer and diatomite and is characterized by also comprising rubber powder. The weight portions of rock asphalt, polymer, diatomite and rubber powder are respectively 5 to 15, 15 to 33, 20 to 30 and 60 to 74. Rock asphalt, polymer and diatomite are ground, added with rubber power and then placed into a mixer according to the above weight portions; then the mixture is extruded into strips by a screw extruder, then cut into granules after cooling and finally dried. The invention has the advantages of obviously reducing the tire noise caused by road driving, and having safe and simple usage, uniform dispersion, high-temperature rut resistance, low-temperature crack resistance, low cost and relatively high performance price ratio.

Description

Technical field [0001] The invention relates to a noise reduction and anti-rutting agent, which is mainly used for being miscible in the surface layer of an asphalt pavement to improve the high-temperature stability of the surface layer asphalt mixture and the noise reduction and anti-rutting ability of the road surface. Background technique [0002] Under heavy load and channelized traffic conditions, rutting has always been one of the main diseases of asphalt pavement. Severe rutting seriously jeopardizes driving safety, and other types of diseases, such as oiling and cracking, are often accompanied by rutting. If maintenance is not carried out in time, the service life of the road surface will be greatly shortened. However, it takes a lot of maintenance funds to treat rutting. Practice has proved that the use of asphalt mixtures with strong anti-rutting ability in new construction or major repairs can minimize the occurrence of rutting on asphalt pavements, and will greatly re...
