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。
Compared with ordinary road concrete, high performance concrete road requirements of raw materials more stringent, with the ratio of design also has its special requirements. Although the road high performance concrete with fly ash and polypropylene fiber can not improve the strength greatly, it can significantly improve the pavement performance, the test results show that its wear can be reduced by more than 60% and the fatigue life can be increased by 2 times .
