Abstract
The soils of rural roads in Guayas province are characterized by being clayey and expansive, causing problems for vehicular and pedestrian traffic. This research analyzes the use of gravel as granular material in its natural state and then combined with another aggregate of the same category for soil stabilization. A qualitative experimental procedure was conducted to obtain laboratory results from natural and combined samples. After testing, soil properties were compared in both states, determining that a 50% dosage of each material improved the soil’s physical-mechanical characteristics: reduced plasticity index, increased maximum dry density, and significantly improved bearing capacity, meeting MTOP guidelines for subgrade improvement with selected material.
Author Keywords: soils, combination, stabilization, gravel, testing.
