Experimental study on usage of (PET) waste plastic incorporating with (TIO2) titanium dioxide for the construction of plastic roads

Abstract

Plastic waste, which is observed to be very harmful for the habitat, is found to be occur around 5% in municipal solid waste (MSW). Currently a critical problem is the discarding of plastic waste. These waste plastics are everlasting, which in turn contributes to the immense environment contamination and public health troubles. The several researches at different institutes advised that this waste plastic can be utilized for the purpose of construction of asphaltic pavements. The usage of this plastic waste for constructing pavements is depended on the economic, technical and ecological criteria. If this waste plastic be used properly for the manufacturing of roads, discarding and problems of contamination will be diminished to a great extent. The main aim of this study is to find out the maximum proportion of plastic waste which will be added in the constructional mix for getting the mandatory strength. The main focus of this study is to how the amount of waste plastic will be increased when a suitable amount of an admixture like tio2 will be blended to the normal plastic waste mix which will be utilized for the manufacturing of waste plastic pavements. Two kinds of plastic waste samples were casted, with Tio2 and without Tio2. Both kinds of samples were prepared according to Marshall Mix design prescribed by MORTH (IV revision) on both types of samples, tests like Marshall stability test and indirect tensile strength test were done and then the results were compared. It was observed that the value for both the Marshall stability and indirect tensile strength test shows a huge increase in their respective value of plastic samples blended with Tio2 when compared to the normal plastic waste samples at 17% of waste plastic, the Marshall stability value observed to be the maximum and however for the indirect tensile strength at 17% of plastic waste blended with 17% Tio2 shows the highest values when compared to normal plastic waste samples. It was seen that utilizing Tio2 as an admixture has given outstanding results and demonstrated maximum values for engineering and rheological properties like Marshall Stability, Deformational flow, density, water resistance and indirect tensile strength etc.
