How do lime soil twelve percent ash dose?
Some problems of lime ash dosage of 2008-12-05 11:46 is currently in the highway engineering, lime soil is widely used in subgrade and pavement subbase, lime stabilized soil has good mechanical properties and resistance of water stability and a certain degree good, the early strength and water stability of low strength high. But it is easy to produce cracks because of shrinkage and cold shrinkage, so it is not suitable to be used as the base of advanced pavement.
Technical specification for construction of only write is lime / dry soil, and the lime is slaked lime or lime definition is very vague, but the budget made it clear that the amount of lime dosage, according to the empirical data, 1m3 428.4kg (lime lime lime powder 50%, 50%),. Lime loose dry density is 550 kg/ m3, you can calculate the coefficient, mixed with lime and lime: 550/428.4=1.28, so in the process of construction, supervision engineers tend to demand by type
The road mix method and plant mixing method of two kinds of main construction method of lime stabilized soil, no matter what kind of construction method, the main indicators of control in the construction process there is moisture, ash dosage, degree of compaction, particle size, thickness, the ash dosage is a crucial factor, the size effect of ash to lime dose the strength and degree of compaction, and the optimum water content and other indicators, has very important significance on the quality of the lime soil, therefore, combining with construction experience, talk about a few views on ash dosage, for everyone to explore.
