Resumen

This study evaluated the effect of hydrated lime (5%, 10%, and 15%) on the improvement of sandy soil from Cajamarca, Peru. Standard laboratory tests were conducted, including sieve analysis (ASTM D421), Atterberg limits, and modified Proctor compaction (ASTM D1557). The results showed that lime addition increases the optimum moisture content (from 12.72% to 13.91%, 15.10%, and 14.25%) while slightly reducing the maximum dry density (from 1.61 to 1.60, 1.58, and 1.60 g/cm3). The 5% lime content proved to be the most efficient, achieving adequate compaction with a moderate increase in moisture. These findings support the use of lime as an economical and sustainable stabilizer for sandy soils.
