【摘要】 旧水泥混凝土路面薄层沥青加铺层综合处治的主要任务是如何防治沥青加铺层内裂缝的产生、发展,压浆技术处治脱空的好坏直接影响到了加铺层的厚度和效果。结合S116线500m长的旧水泥混凝土路面加铺沥青薄层试验段压浆技术的具体实施,提出了通过控制压浆技术处治后旧路面板接缝的弯沉差来保证加铺沥青薄层的使用效果。更多还原

【Abstract】 The main task of complicatedtreatment of used concrete pavement asphalt thinoverlay is to prevent the appearing and growing ofasphalt overlay cracks.The pumping degree bygrouting technique could influence the thicknessand effect of overlay construction directly.Combined with the testing segment(Line S116 long500 m)of used concrete pavement asphalt thinoverlay, it is indicated that controlling joint deflectiondifference after grouting techniques to improve theeffect of overlay application.更多还原
