Abstract
The invention discloses anti-rutting particles, which are prepared by compounding the following components in percentage by mass: 60 to 75 percent of low density polyethylene, 10 to 25 percent of high density polyethylene, 10 to 20 percent of resin, 5 to 10 percent of rock asphalt and 0 to 5 percent of rubber powder. The anti-rutting particles can enhance the interaction and integrity of an asphalt mineral powder cementing material system, improve the property of an asphalt mixture, improve the high-temperature stability and strength of the asphalt mixture, and achieve the anti-rutting capability of an asphalt pavement.
Description
Technical field
The present invention relates to the additive that uses in a kind of asphalt, particularly relate to a kind of anti-rut particle.
Background technology
The main disease of China's bituminous pavement is that rut makes the surface evenness variation, and occurs phenomenons such as check crack, hole, hole and hole groove very soon, makes the well damage on road surface, influences the normal traffic operation.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that exists at prior art, and a kind of anti-rut particle is provided, and it can increase road surface bearing capacity and wear resisting property, prolongs road surface working life, and saves the pavement recondition expense.
For solving the problems of the technologies described above, the technical solution used in the present invention is: 1. anti-rut particle, it is characterized in that, be composited by new LDPE (film grade), high density polyethylene(HDPE), resin, rock asphalt and rubber powder, their mass percent is: new LDPE (film grade) 60～75%, high density polyethylene(HDPE) 10～25%, resin 10～20%, rock asphalt 5～10%, rubber powder 0～5%.
Its preparation method is: new LDPE (film grade), high density polyethylene(HDPE), resin, rock asphalt and the rubber powder of above-mentioned mass percent are dropped into the screw extrusion press blend according to proportioning, be cut into particle by cold drawn granulate equipment again and get product.
The present invention compared with prior art has the following advantages: outward appearance of the present invention is particulate state, its with the heating after the asphalt mixture whipping process in, particle in the collision of hot mineral aggregate, shear that wire drawing becomes plastic optical fibre under the comprehensive action, in the skeleton that gathers materials, put up a bridge crosslinked and form fiber and steel bar reinforced effect; Simultaneously, because the existence of polymer fiber, it is netted to make that it forms in agglutinate, having strengthened asphalite arogel ramming material system interacts and globality, and then modification the performance of asphalt, improve stability at high temperature of asphalt mixture and intensity, and reached the rutting resistance of bituminous pavement.
The invention will be further described below in conjunction with specific embodiment, and embodiment is just to explanation of the present invention and non-limiting.
