Abstract

The invention provides an anti-rut agent. The anti-rut agent comprises white carbon black, a polyolefin elastomer and an additive. The invention provides an asphalt mixture. The asphalt mixture comprises an anti-rut agent, mineral aggregate and matrix asphalt. The invention provides a preparation method of the anti-rut agent. The preparation method comprises the following steps: adding white carbon black, a polyolefin elastomer and an additive into a high-speed mixer in proportion; and conducting mixing, banburying, extruding and granulating by using a high-speed mixer to obtain the anti-rut agent. The invention provides a preparation method of the asphalt mixture, which comprises the following steps: fully mixing the anti-rut agent and liquid matrix asphalt, spraying an obtained mixture into a hot mineral aggregate by an asphalt pump, and fully conducting mixing. The anti-rut agent and the asphalt mixture have the properties of vehicle withdrawal resistance, water damage resistance, low-temperature crack resistance, aging resistance and the like, and the service life of an asphalt pavement can be remarkably prolonged. The preparation method disclosed by the invention has the characteristics of simple process, low cost, continuous production, convenience in transportation, easiness in popularization and use, good benefit and the like. The anti-rut agent and asphalt mixture can be widely applied to the traffic field.

Description

Technical field[0001]The present invention relates to the field of road construction, and more particularly to an anti-vehicle rutting agent, an asphalt mixture, and a method of preparing a cargoer and a bitumen mixture.Background technique[0002]With the development of technology, economy, people's pursuit of life has also put forward higher requirements. At present, whether it is a city or a country, in order to produce and live, it has been carrying highway construction, such as the renovation of the road, the construction of new planning roads. It is well known that due to the quality, performance and use of the highway, the performance and service life of the road have received great impact, such as the anti-crack resistance, load reproduction of the road. Although relevant departments and companies have always been committed to the improvement and maintenance of road quality, the construction and repair of the road still affect people's production and life.[0003]It can be seen ...
