目前我国已建和在建的桥梁,大多采用普通沥青混凝土作为复合桥面铺装的上面层。沥青混凝土作为桥面铺装,要求应有比道路沥青混凝土面层更好的高温稳定性、低温抗裂性、疲劳耐久性和抗水性能。文章通过工程实例和有关试验,表明聚酯纤维材料用于沥青混凝土桥面铺装可以显著提高沥青混凝铺装的路用性能。 At present, China has built and under construction bridges, most commonly used as a composite asphalt concrete pavement deck above. As a bridge deck paving, asphalt concrete should have better high temperature stability, low temperature crack resistance, fatigue durability and water resistance than the asphalt concrete pavement. Through engineering examples and related tests, the article shows that the use of polyester fiber material for asphalt concrete pavement can significantly improve the pavement performance of asphalt concrete pavement.
