Rubber asphalt modifier and production method thereof

Abstract

The invention discloses a rubber asphalt modifier and a production method thereof. The rubber asphalt modifier comprises the following components in parts by weight: 80-85 parts of rubber powder and 15-20 parts of Vestenamer which is a chemical material. The production method of the rubber asphalt modifier comprises the following steps: mixing the rubber powder and the Vestenamer, grinding into binary mixture at the temperature blow 80 DEG C, and extruding the binary mixture into irregular granules with the size of 3-6mm by using a shaping granulator. The rubber asphalt mixture used on the rubber asphalt road surface can be more easily and directly produced from the asphalt of common matrix by adding the granules to a mixture stirrer, thus the performance advantage of the original rubber asphalt mixture is enhanced, the defects of complex production process and high cost of the prior production mode are overcome, the dense smoke and the foul smell generated in the process of rubber asphalt mixture construction are effectively reduced, and the environmental problem resulted from the usage of rubber asphalt is alleviated.

Description

technical field [0001] The invention relates to a rubber asphalt modifier and a production method thereof, which are mainly used for mixing with base asphalt and other materials (such as stones) to produce rubber modified asphalt mixture for laying road surfaces. Background technique [0002] The existing rubber asphalt use technology is to use special rubber asphalt modification equipment to heat the base asphalt to 165-170°C and then mix it with rubber powder, and continue to stir and keep warm for more than 32 hours to produce rubber modified asphalt, and then in During construction, put this rubber-modified asphalt into the mixing tank, and mix it with other materials (such as stones, etc.) to produce rubber-modified asphalt mixture for laying road surfaces. Compared with the traditional asphalt pavement, this kind of asphalt mixture has the advantages of noise reduction, anti-rutting, anti-skid, and mitigation of rain, snow and freezing hazards. However, this method ne...
