Rubber asphalt concrete and preparation method thereof
The invention provides rubber asphalt concrete and a preparation method thereof.The preparation method of the rubber asphalt concrete comprises the following steps that 56-60 parts of coarse aggregate and 35-40 parts of fine aggregate are stirred in a stirring pot at the temperature of 160-180 DEG C for 90 s, 4-6 parts of water-swellable rubber modified asphalt is heated to 160-180 DEG C and then added into the stirring pot to be stirred for 90 s, and the rubber asphalt concrete is obtained. And finally, adding 4-6 parts of filler, and stirring for 90s to obtain the rubber asphalt concrete. Compared with matrix asphalt concrete, the prepared rubber asphalt concrete has the advantages of good high and low temperature performance, aging resistance, reflection crack resistance, low noise, smoothness, comfort, good skid resistance and the like. The characteristics of the water-swelling rubber can be fully utilized to absorb the moisture of the asphalt pavement, reduce the pavement temperature and reduce the pavement water seepage phenomenon, so that the durability pavement performance of the asphalt concrete is improved to a great extent.
本发明提供一种橡胶沥青混凝土及其制备方法，所述的橡胶沥青混凝土的制备方法包括如下步骤：把56‑60份的粗集料、35‑40份的细集料于160℃～180℃搅拌锅中搅拌90s，把4‑6份的遇水膨胀橡胶改性沥青加温至160～180℃，然后加入搅拌锅中进行搅拌90s，最后加入4‑6份的填料搅拌90s，制得一种橡胶沥青混凝土。相比于基质沥青混凝土，该制备的橡胶沥青混凝土具有良好的高低温性能、抗老化性、抗反射裂缝、低噪声、平整舒适及较好的抗滑性等优点。能够充分利用遇水膨胀橡胶的特性，吸收沥青路面的水分，降低路面温度，减少路面渗水现象，很大程度上提高了沥青混凝土的耐久性路用性能。
