Problems solved by technology

[0002] With the increasingly tense environmental protection situation, the ecological balance has been severely damaged, and the recycling of waste has become an important way to ease the ecological balance. Waste fiberglass asphalt shingles and waste rubber materials account for a large proportion of waste products. The usual treatment method is to take the waste to the treatment plant for waste treatment, but the simple treatment of the treatment plant cannot recycle these wastes well, and the recovery rate is not high, which makes the resource utilization rate low and cannot play a role. good environmental protection

Abstract

The invention discloses a novel asphalt cold-patch material and a preparation method thereof, belonging to the technical field of pavement patching. The preparation method is used for recycling wastetiles and waste rubber materials to prepare the asphalt cold-patch material and comprises the following steps: (1) crushing waste glassfiber asphalt shingles; (2) pouring the waste rubber materials into a batching tank for heating and melting, adding the crushed waste glassfiber asphalt shingles and asphalt after the waste rubber materials are completely melted, heated and dehydrated to a state ofno obvious bubbles, and then carrying out heating and uniform stirring; (3) after the glass fibers in the batching tank are completely dispersed into threads and the materials are uniformly dispersed, conducting cooling to 120 DEG C, adding a cold-patch modifier, and conducting uniform mixing; and (4) adding stone and the materials in the batching tank into a stirring tank, and carrying out uniform stirring to obtain the asphalt cold-patch material. According to the invention, the waste glassfiber asphalt shingles and the waste rubber materials are made into the asphalt cold-patch material, so waste garbage is changed into a new product, waste recycling is realized, and the prepared asphalt cold-patch material has excellent performance.
