| 摘 要： | 路面结构层间铺设聚酯玻纤布可有效地延缓反射裂缝病害的发生,其黏附性对防治反射裂缝的效果至关重要。对采用乳化沥青等四种粘结材料的试件分别进行层间滑移剪切试验和层间挤压剪切试验,对比研究四种不同粘结材料的抗剪强度以确定最佳粘结材料;通过试验研究层间粘结性能随用量的变化趋势,确定了最佳用量。研究表明铺设聚酯玻纤布下的最佳粘结材料为SBS改性沥青,其用量不得低于0.45kg/m~2,最佳用量为0.93kg/m~2。

| Abstract: | Fiberglass-polyester paving mat can effectively delay the reflection crack defect, its adhesion is of vital importance to the prevention of reflection crack. Interfacial slipping shear test and interfacial extruding shear test have been carried out with four kinds of adhesive material, comparison and analysis on the shear strength of four different adhesive materials have been im-plemented to select the best adhesive material. By analyzing the changing law of shear strength under different dosages of the ad-hesive material, the best dosage of adhesive materials could be determined. The results have shown that, the SBS modified as-phalt is the best adhesive material, and the minimum dosage is no less than 0.45 kg/m2, the dosage of 0.93 kg/m2 is the best. |
