Study on Use of Plastic Waste in Road Construction

The population growth, industrialization, consumerism and technological development have led to uncontrollable accumulation of waste. Proper waste disposal is of great importance in both rural and urban areas. This study discussed the suitability of plastic waste materials for pavement construction.. The waste is mixed in different proportions to the soil sample and their influences on geotechnical properties were studied. The results of the tests indicated that plastic alone is not suitable for pavement subgrade. When quarry dust was added along with soil plastic mix,it maintains the CBR value within the required range.
