Inorganic Binding Material Stabilized Gravel Road Performance

Our country territory is broad, and the natural gravel distribute extensive. Along with the scale of national enlargement infrastructure, research and solve lots of problems that turn up in the application of inorganic binder gravel. It is very important to popularize the application of inorganic binder gravel and protect zoology.The text researched the pavement performance of inorganic binder gravel. Comparing the different scheme with synthetically analyzing test and analyze the pavement multi-performance, including mechanical performance, the anti-crack performance, anti-brushing performance and fatigue performance. In the research, the 7d compressive strength and 7-180d strength growth rate were considered as mechanics guideline; the dry shrinkage craze coefficient and the temperature shrinkage craze coefficient were considered as anti-crack guideline; the stress ratio of 106 fatigue time was considered as anti-fatigue guideline; the average brushing quantity was considered as anti-brushing guideline. Base on these guideline, the inorganic binder gravel with skeleton-density structure had the best synthetic pavement performance and the best mix proportions fit for base course had been put forward.It had been put forward fist time of temperature accumulate in the article, pavement performance had been researched through making use of temperature accumulate. The 7d compressive strength norm,compressive modulus of resilience and splitting strength in different construction season had been put forward throughout the regression relation between strength growth rate, modulus of resilience growth rate, splitting strength growth rate and temperature accumulate, it provided the control objectives for construction and designing.
