旧水泥混凝土路面微裂均质化处治技术在"白加黑"路面再次改造工程中的应用

Application of Micro-crack Homogenization Treatment Technology for Old Cement Concrete Pavement in"Cement+Asphalt"Pavement Reconstruction Project

通过对"白加黑"路面常见病害调查及原因分析,认为旧水泥混凝土路面板的纵横缝及一些裂缝这一初始缺陷是加铺沥青混凝土面层开裂以及扩展的主要原因.结合工程实例介绍了旧水泥混凝土路面微裂均质化处治技术在"白加黑"路面再次改造工程中的应用.工程实践表明,微裂均质化再生技术在"白加黑"路面再次改造中,具有良好的工程效果,可进一步推广应用.

Through the investigation and analysis of common diseases and causes of"cement+asphalt"pavement,itis considered that the longitudinal and transverse joints and some cracks as the initial defects ofold cement concrete pavement are the main causes for the cracking and expansion of asphalt concrete pavement.Combined with the engineering examples,the application of micro-crack homogenization treatment technology for old cement concrete pavement in the"cement+asphalt"pavement reconstruction projects is introduced The engineering practice shows that the micro-crack homogenization treatment technology has the good engineering effect in the"cement+asphalt"pavement reconstruction projects,and can be further popularized and applied.
