| Summary: | Most areas in the Philippines experience high road construction cost due to the limited supply of suitable materials for road embankment within economic haul distances. Considering that the country is currently having extensive infrastructure development, potential use of naturally-occuring materials such as limestones was tested resulting not only as an economic alternative to the conventional materials, but leading to an improved strength of roads. Geotechnical and morphological properties of pure and blended materials were determined characterizing the behavior of the strength of the materials as limestone blend varies. A 50% blend of limestone to conventional road base materials provided optimum strength increasing the values up to 30%, 100% and 40% for unsoaked CBR, soaked CBR and UCS, respectively. © 2016, Int.
