The Research And Experiment Of The Material Structure Of The Base With Gap Filling Macadam

For several years,in company with the development of rural economics in Fuxin City,the old soil surface structure already impact and rejection the expanding economy and trafficking in Fuxin City.So,cnstructs the road throughout villages is one of grand strategy in the economic development of Fuxin City.As a result of Fuxin region is dry and shortage,and falls across aeolian soil and macadam at the course of highway construction,the shimming macadam by dry process executive fits the region which is drought,shortage and has so much macadam in Fuxin.The structural shape gets material abroad,carrying capacity is better,craft simplicity,cost low,conform to the particular of engineering in Fuxin region.The text introduce the basic property of raw material with base stuff shimming macadam,and proceed many test and analyses to them.utilize Uniformity design method to designing experiment,got the optimum proportioning of coarse aggregate. To get the most destroy value of pavement receive loading,the relation of pressure and pavement subsidence and the relation of subsidence and time with these material,for the first time exploratory simulation test road with hyaulic contractor indoors,and brought in model proceed load test.And simulation it with ADINA software,finally,to analyses get result that shimming macadam base reach engineering requisition,has supervise sense.
