为研究极端气候条件下铺设玻纤格栅沥青混凝土结构的性能,通过WDW-1020微控电子万能材料试验机和HYCZ-5A双轮自动车辙试验仪分别进行了室内小梁弯曲试验和车辙试验,分别评价了复合型路面的极端低温抗裂性能与高温稳定性能。研究结果表明,通过布设一定强度的玻纤格栅加筋有利于提高路面的抗弯拉强度、弯拉应变、动稳定度;加筋复合路面具有优良的低温抗裂性与高温稳定性。
In order to study the performance of fiberglass-grille asphalt concrete pavements under extreme climatic conditions, the indoor trabecular bending test and rutting test were carried out respectively by WDW-1020 micro-electronic universal testing machine and HYCZ-5A two-wheel automatic rutting tester. The composite composite pavements were respectively evaluated for their extreme low temperature crack resistance and high temperature stability. The results show that the reinforcement of the glass fiber reinforced plastic (GRG) with certain strength can improve the flexural strength, flexural strain and dynamic stability of the pavement. The reinforced composite pavement has excellent low temperature crack resistance and high temperature stability.
