| Summary: | addition of low percentage of lime to both of these aggregate contained little, if any, clay minerals and it was aggregates are normally stabilized with very low percentage aggregates which were observed in Texas triaxial compression also demonstrated that the addition of hydrated lime analysis revealed that quartz-rich limestone and caliche atterberg limit testing, scanning electron microscopy calcium carbonate to dissolve and reprecipitate as a Carbonate cementation is a natural phenomenon. Constant cementing agent. Research showed that this natural tendency Defectometer was used to back calculate moduli values of the due to the addition of small percentages of lime. Testing examinations, resilient moduli determination of the materials extensively to examine the effect of carbonate cementation fluctuation of the chemical conditions in the nature causes heavily stabilized subgrade, carbonation reaction is likely in the lab and in the field. Caliche and limestone base included mineralogical analysis of the two materials, increased the moduli values of the aggregate regardless of material type, curing time, and moisture condition. materials stabilized with either I or 2 percent hydrated lime of carbonate cementation can be enhanced by adding lime to of lime. While pozzolanic reaction is expected to occur in pavement layers using the program MODULUS. Mineralogical percentage of lime because of little or no clay in them. In reaction for that reason. Strength increases due to the reaction. Laboratory and field testing for resilient moduli South Texas, limestone and caliche soil, were tested strength analysis in terms of texas triaxial strength, tests were most likely to be the result of carbonation Texas to stabilize base and subgrade materials. Base course the anal yses 1 i sted above. In addition, Falling Weight the system. Lime is used in many places and especially in this research, two base course materials commonly used in to be prominent in base courses stabilized with low unlikely for these aggregates to experience pozzolanic were compared to control (unstabilized) materials in terms of |
