| 摘 要： | 与普通道路混凝土相比,道路高性能混凝土对原材料的要求更为严格,配合比设计也有其特殊要求。掺加粉煤灰和聚丙烯纤维的道路高性能混凝土虽不能大幅度提高强度,但可显著改善路面的路用性能,试验结果表明其磨耗量可降低60%以上,疲劳寿命可提高2倍以上。

| Abstract: | Compared with normal concrete,highperformance road concrete has more rigorous requirements than raw materials and specific demand on mix design.Though high-performance road concrete mixed with fly ash and polypropylene fibre can not increase strength in wide-range,they can significantly improve the pavement performance.The test results show that abrasion value can depress more than 60% and endurance life can increase more than 2 times. |

| Keywords: | high-performance road concrete fly ash polypropylene fibre raw material mix proportion road performance |
