| 1. | Periodic maintenance and rehabilitation can prolong the road ' s service life . an asphaltic overlay is applied to the old pavement surface in good time , which not only enhances the strength of the pavement , but also improves the using performance of the old pavement instead of doing lots of rebuilding works . therefore , the thickness of asphalt concrete overlays is less than the thickness of the reconstructed pavement
定期的养护与维修可以延长沥青路面的使用寿命，及时地在沥青路面上加铺罩面，不仅可以增强路面强度，还可改善路面的使用性能，而不必做大量的重建工作，其厚度也小于重建施工的厚度，因此对于已破损的路面，采用沥青混凝土罩面常可以提供最经济的修复形式。 | | 2. | Two different reinforcing methodologies are applied : modification of the overlay characteristics by adding chopped glass fibers to the hot mixture asphalt ( hma ) and reinforcing asphalt overlay with glass grids . theory of fracture mechanics ( fm ) is employed to determine crack growth rates for the suggested anti - cracking overlay systems . asphalt mixture designing tests , three point bending tests and fatigue crack propagation tests were carried out . the critical stress intensity factors kic are determined for plain and reinforced asphalt concrete . depending on the fatigue crack propagation , the crack growth rate is determined for each type of anti - cracking system and the cracking process is also analyzed . one of the significant points in this study is the attempt to give better understanding of the crack propagation for multilayer asphaltic overlay or what are suggested herein to be called composite structure anti - cracking overlay system . the results indicate that the reinforcing materials improve anti - cracking characteristics of the asphalt concrete . composite structure anti - cracking overlay gives a good solution for the reflective cracking phenomenon over old cracked pavements
利用2种不同的方法加筋沥青罩面:在沥青混合料中加入短切玻璃纤维改善沥青混凝土的特性,采用玻璃格珊加筋沥青混凝土.应用断裂力学方法分析沥青路面裂缝扩展机理.采用沥青混合料设计试验、三点弯曲试验和疲劳裂缝扩展试验,确定加筋沥青混凝土的临界应力强度因子kic ,测量每一种沥青罩面抗裂系统的裂缝扩展速率.本研究的主要特点是提出复合型抗裂罩面系统,分析了多层加筋沥青罩面裂缝扩展过程,推荐了若干沥青路面抗裂系统.结果证明,加筋材料可以提高沥青罩面的抗裂特性,复合型抗裂罩面系统能够有效地阻止反射裂缝的扩展 |
