Embodiment
A kind of rubber pitch modifier of the present invention is characterized in that, its component and parts by weight are respectively and are the rubber powder: 80～85, Vestenamer rubber accelerator: 15～20.
The working method of described rubber pitch modifier is characterized in that, may further comprise the steps:
(1) rubber powder and industrial chemicals Vestenamer rubber accelerator are mixed with the 8:2 part by weight, add in the steel mill that has refrigerating unit and pulverize, working temperature is lower than 80 ℃, with anti-aging.Binary compound behind the wearable is not more than 60 orders.
(2) use the shaping granulator with the irregular particle of described polynary compound extruding as particle diameter 3～6mm,
The present invention mixes chemical materials Vestenamer with rubber powder as rubber powder and bituminous are material modified according to optimal proportion, form rubber pitch modifier and directly apply to and produce its advantage of rubber-asphalt mixture and be:
1, the effect owing to Vestenamer in the rubber pitch modifier makes rubber and pitch that better clinkering property arranged; Thereby better Pavement Performance is arranged than original rubber-asphalt mixture; High temperature and low-temperature stability all significantly increase, and anti-rut, cracking resistance seam also slow down the road surface and wear out.
2, this novel rubber asphalt modified product can directly cooperate with matrix pitch and be used to produce rubber-asphalt mixture, when producing, does not need special devices and preparation technology, greatly reduces production cost.
