摘要
通过对聚酯纤维增强沥青混凝土进行马歇尔试验、间接抗拉强度试验、蠕变试验和车辙试验等特性研究,结果表明,纤维对沥青混凝土的增强作用是明显的。短细的纤维在沥青中起到提高粘结性、热稳定性、抗流变性等作用,提高了抗压、抗拉、抗剪等力学强度。该试验结果在公、铁路两用大桥桥面铺装实桥试验段中获得了成功应用。
Through a series of such tests on polyester fiber reinforced asphalt concrete as Marshal test,indirect test of tensile strength,creep test and rut test,the results showed that the effect of fiber reinforced concrete is evldence.The shortness fiber which in the bitumen play a key role in enhancing bonding performance.thermal stability and rheological resistance properties, which also reinforce the mechanical strength of bitumen such as compreesive resistance,tensile resistance and shear resistance.The test results are well applied to the deck surfacing of bridge both for highway and railroad.
