目前,山东省公路通车里程达到71128公里,其中高速公路已达2411公里,实现了省会济南与16个地级市全部通了高速公略;高级、次高级路面铺装率达到81%,其中沥青路面已达54055公里,占通车里程的76%。上述数据表明,沥青路面的养护任务越来越繁重,面临需要解决的技术问题也非常迫切。养护工程与新建工程有着不同的特点,新建工程的运作程序是:立项→前期工作(包括预可、工可、初步设计等)→施工图设计→组织实施;养护工程的运作程序是:数据采集→数据分析→提出建议→批准立项(决策)→施工图设计→组织实施。新建工程是立项在先,
At present, the highway mileage in Shandong reaches 71,128 km, of which the expressway has reached 2,411 km, realizing the completion of the highway strategy between Jinan and 16 prefecture-level cities in the provincial capital; the pavement rate of advanced and sub-advanced roads reaches 81%, of which asphalt The road has reached 54055 km, accounting for 76% of the traffic mileage. The above data show that asphalt pavement maintenance tasks more and more heavy, the technical problems to be solved is also very urgent. The maintenance project and the new construction project have different characteristics. The operation procedure of the new construction project is: project → preliminary work (including pre-feasibility study, engineering design, preliminary design, etc.) → construction drawing design → organization and implementation; conservation project operation procedure is: → Data Analysis → Suggest → Approve Project (Decision) → Construction Design → Organize Implementation. The new project is the first project,
