SMA rubber asphalt mixture doped with rubber powder and preparation method of SMA rubber asphalt mixture
The invention discloses an SMA rubber asphalt mixture internally doped with rubber powder and a preparation method thereof.The SMA rubber asphalt mixture is prepared from, by weight, 800-900 parts of aggregate, 40-60 parts of asphalt and 6-12 parts of filler. According to the SMA rubber asphalt mixture internally doped with the rubber powder and the preparation method thereof, the rubber asphalt internally doped with the rubber powder is adopted as a cementing material, use of a fiber additive is reduced, and the service life of the material is prolonged; the storage stability at 163 DEG C and 48h is less than or equal to 2.5 DEG C, so that the high and low temperature performance of the asphalt mixture is effectively improved, the fatigue life of the asphalt mixture is prolonged, the material is more stable, and the economic and social benefits are higher.
本发明公开了一种内掺胶粉的SMA橡胶沥青混合料及其制备方法，所述SMA橡胶沥青混合料包括以下原料组分及其重量组份为：集料800‑900份，沥青40‑60份，填料6‑12份，本发明采用内掺胶粉的橡胶沥青为胶结料，减少纤维添加剂的使用，其在163℃、48h储存稳定性≤2.5℃，有效提高了沥青混合料高低温性能，还提高了沥青混合料的疲劳寿命，使得材料更加稳定，具有较高的经济社会效益。
