Road Performance Study Of The Inorganic Binder Stabilize Ceramisite And Macadam Baes Material

Because of the lower density and the porosity inside even with strength and firmness, ceramisite is widely used in construction, chemistry, agriculture, etc. The ceramisite use in the road base, not only can satisfy the related request, but also enable to improve the road performance to a certain degree. Every year our country has about more than one hundred million stere dredged mud dump into sea that badly damaged the environment of the sea, using the dredged mud ceramisite into base realize the reducing of the dredged castoff, at the same time it provides the new road material for the few stone area of the seashore. This article provides a large of relevant performance data for ceramisite using in base, also makes groundwork for mastering performance of ceramisite truly via vast lab tests, and establishs the groundwork for urging the broad application of inorganic binder stabilize the ceramisite and macadam.The main studying contents in this article conclude:1. Selecting the semi-rigid base material and testing each raw material's physical, chemistry and the mechanical properties, and it carries on mixture ratio design to the cement-stabilized and lime-fly ash stabilized ceramisite and macadam.2. On the background of common semi-rigid base course function, this article studies the mechanical function, stabilization performance and shrinkage performance and so on to this base material, it also contrasts and analyzes the road performance via testing result.3. According to the actual situation of the experiment road, it gives the suggestion and the attention from the raw material, the mixture ratio design and the construction technics, and will investigate the intensity and crack and so on in the near future, also it will contrast with the laboratory test conclusion simultaneously.Through lots of the experiments, the biggest dry density and the best water content of the cement stabilized ceramisite and macadam and lime-fly ash stabilized ceramisite and macadam is given, and it ascertains the best ceramisite proportion, so designs the cooperate proportion of the mixture material; On the mechanical function,studies show 7d unconfined compressive strength reach the standard in which used the half of ceramisite as substitute in road base materials, furthermore, the performance of frost resistance and drying shrinkage performance represent very well; In the end, it gives the suggestion to the experiment road, and provides the available foundation for this material's optimization design and the science construction.
