Analysis on the overall paving process of cement stabilized aggregate base course with wide width and large thickness and its applicability in Qinghai Area
In view of the actual situation of pavement engineering in Qinghai area,from the mixing and trans-portation of cement stabilized aggregates,paving and compaction of three aspects,the construction technology of wide width and large thickness cement stabilized grass-roots level is investigated;by comparing the traditional ce-ment stabilized aggregates grass-roots level and machine paving construction technology,the advantages and exist-ing problems of the overall paving technology of wide width and large thickness cement stabilized aggregates grass-roots level are summarized in the application of the technology in Qinghai area.Problems.The study and analysis show that:in the overall paving process of wide and large-thickness cement stabilized aggregates grass-roots lev-el,it is necessary to improve the corresponding mixing and transportation capacity,choose the two main paving processes according to the actual project,and make the overall compaction of grass-roots level meet the require-ments through reasonable mechanical combination,and make the difference between the upper and lower compac-tion degree smaller;from the consideration of the construction and performance factors,wide and large-thickness cement stabilized aggregates grass-roots level overall paving technology can be applied to pavement projects in Qinghai area,and the advantages and existing problems are summarized.Considering both construction and per-formance factors,wide and large thickness cement stabilized aggregates paving technology has higher applicability and better social and economic benefits in Qinghai pavement project,and it is recommended to be promoted and applied in engineering practice in combination with the actual project.
