| 摘 要： | 为评价天然沥青BMA对沥青路面的贡献,对BMA改性沥青及沥青混合料进行了室内性能试验,并铺筑了天然沥青试验路。室内试验结果表明,BMA天然沥青能显著提高沥青混合料的高低温性能、抗水损害能力,试验路也证明采用BMA天然沥青的沥青路面具有良好的抗车辙能力和耐久性,能提高道路的服务水平。BMA天然沥青能延长路面正常使用寿命,降低路面维修费用,适用于重载道路、钢桥面铺装、机场道面等场合。

| Abstract: | In order to evaluate the contribution of natural BMA bitumen to bitumen pavement.the performances of modified BMA bitumen and its mixture are tested in labratory.A experimental natural bitumen road is paved.Experimental result shows that BMA natural bitumen can improve the performance of mixture with bitumen at low and high temperature,the capacity can improve the performance of mixture with bitumen at low and high temperature,the capacity of motsture resistance damage.The test proves that pavement with BMA natural bitumen has good rutting resistance and durability of postponing its service life.So it can be applied for heavy road.pavement of steel deck and airfield runway etc because of its longer service life and lower maintenance cost. |

| Keywords: | natural bitumen BMA stability at high temperature crack resistance at low temperature moisture resistance damage |
