土工合成材料对沥青路面力学性能影响研究

Study on Influence of Geosynthetic Material on Mechanical Properties of Asphalt Pavement

分别采用4种加固方式的沥青混凝土试件和未加筋试件,进行循环荷载作用试验,研究采用不同类型土工合成材料加固对沥青路面力学性能的影响。结果表明:利用土工格栅进行加固的沥青混凝土试件,在承受重复荷载方面表现出显著的优势;沥青混凝土与钢筋之间的黏结性质是影响加固效果的重要因素。

The asphalt concrete specimens reinforced by 4 methods and the specimens not reinforced were used in cyclic loading tests to study the influence of the reinforcement in different geosynthetic materials on the mechanical properties of asphalt pavement.The result shows that,the asphalt concrete specimen reinforced by geogrid has outstanding performance in bearing repeated load.The bonding property between asphalt concrete and steel bars is the important factor influencing the reinforcement effect.
