Large road infrastructural development in India is in progress under different national and state programmes viz. Golden Quadrilateral, North- South/East -West corridors, Pradhan Mantry Gram Sarak Yozna (PMGSY), Mukhaya Mantry Gram Sarak Yozna (MMGSY). This resulted depleting of natural conventional road materials. Therefore, there is a need to search alternative road construction technique. Stabilization of soil will be a better option for construction of road. Accordingly, a new liquid soil stabiliser which is polymer product was investigated in the laboratory. Accordingly, four types of soils (gravel, sand, silt and clay) were selected for the study covering wide range based on grain size and liquid /plastic limits. Geotechnical characterization of selected soils was carried out. Selected soils were mixed with cement in varying proportion ranging from 2 to 8 % and geotechnical characterization was carried out. To study the performance of liquid stabilizer, it was blended with soil in the presence of cement and geotechnical characterization was carried out. Addition to that, durability test of stabilised soil samples was also carried out to know the performance in wetting and drying condition. It was observed that there is no clear relationship was developed with using liquid stabilizer on different type of soils (UCS/CBR values). However, it was concluded that the strength of soil B was improved by addition of liquid stabilizer in the presence of cement. |
