The Study Of Cement Fly Ash Stabilized Crushed Stone Subbase Of Technical Performance

China is the world’s biggest coal resources of the national production,In recentyears, as China’s economic construction and the rapid growth of energy demand, thenational implementation strategy for west to east, Guizhou Province, a major electricityexporter of electric power, thermal power industry has doubled development, but theemission of fly ash to.use gap is widening between the, fly ash this "burden" hasbecome a major constraining factor in the development of power industry, as theimplementation of energy conservation in Guizhou Province, building a harmonioussociety and realize sustainable economic development of the main obstacles one.Therefore, how to study fly ash utilization technology, bulk utilization of fly ashconsumption of economic and social development in Guizhou Province is the practicalneeds, is imperative. This research project relying on Science and Technology ofGuizhou Province,"Guizhou highway road fly ash utilization technology research,"complete compliance along the highway on the material properties of fly ash andcement, fly ash stabilized crushed stone sub.base for the study of technical performance,and the mix of construction has been designed.First of all, summed up the fly ash in road construction in a variety of applications,and will be used in the road sub.base to replace part of cement, not only reduces the cost,there are good economic benefits, also described in the current domestic andinternational Research in this area and the latest results.Secondly, through a series of laboratory tests on cement, fly ash stabilized crushedstone materials, physical and chemical properties, strength properties, engineeringproperties of indicators, research, analysis of the cement, fly ash stabilized crushedstone material strength properties and engineering properties.Again, the experimental section of the paving and on.site data collection, furthervalidation of cement, fly ash stabilized crushed stone materials, road performance andeconomy.Finally, in the previous experimental study and theoretical analysis based on theproposed completion of the highway for compliance with cement, fly ash stabilizedcrushed stone sub.base construction with the ratio and construction technology,economic evaluation criteria, which summed up the highway complete compliancecement, fly ash stabilized crushed stone sub.base construction principles for the futurefor this type of road sub.base design and construction of a certain reference.
