There are many studies about how the addition of lime and Rice Husk Ash (RHA) gives the soil a better mechanical behavior, particularly on clayey soils, where usually fine particles reach more than 75%. However, the soils with a small presence of fine particles (59-60%) do not have much research. This investigation evaluates the influence that RHA has on this kind of soil previously stabilized with 3% of lime. After the initial mix of soil-lime, the CBR increased 11.2 times its initial value; within the addition of the ash, the CBR maxed out its value increasing just 1.56%. When 28% of RHA was added, a decay in the value of CBR was noticed. Otherwise, soil workability improved and following the AASHTO standards, the specimens with more ash resulted in a more granular material, with a group index value of 0. The greatest CBR record was obtained when the stabilized soil was added a 16% RHA, reaching a 51.3% CBR, 1.58g/cm3 of MDD and 16.5% of OMC. The CBR of the soil stabilized with lime and the addition of RHA, does not shows substantial improvement, and beyond that the workability seems better, the addition of lime by itself should be enough for an adequate performance for silica-rich clayey soils.
