目前国内外在高速公路沥青混凝土路面养护技术方面已经研发和推广了多项较为成熟的技术措施,形成了一些系统的养护维修技术,如局部修补技术、罩面技术、稀浆封层技术、恢复抗滑能力技术、沥青再生技术等。河北省第一条世行贷款项目石安高速公路通行近8年,急需进行维修。在对路面状况、养护质量进行了充分的调研、检测评价后,经过几次专家咨询会进行维修方案的比选,最终确定采用罩面工程的维修方案。——作者
At present, a number of mature technical measures have been developed and popularized in asphalt concrete pavement maintenance technologies of expressways at home and abroad, and some system maintenance and repair technologies have been developed, such as partial repair technology, overlay technology, slurry seal technology, recovery Skid resistance technology, asphalt regeneration technology. Hebei Province, the first World Bank loan project Shi An Expressway passes nearly 8 years, urgent need for maintenance. In the road conditions, the quality of maintenance conducted a full investigation, after the test evaluation, after several expert consultation will be the selection of maintenance programs, and ultimately determine the use of overhaul maintenance program. - author
