INFLUENCE OF WASTE MATERIALS ON FLEXIBLE PAVEMENT CONSTRUCTION

Bindu C. S

Abstract :

The construction of pavements is costly due to the non–availability of a strong subgrade. This paper focuses on the suitability of clay tile waste as stabiliser in subgrade and demolished concrete waste as subbase in flexible pavement. Clay tile wastes mixed in different proportions to the soil and their influence on geotechnical properties are studied. A study of CBR strength of demolished concrete waste as sub base(GSB) layer underlain by the stabilized subgrade layer is conducted. The optimum percentage of tile waste in the soil is 45%. The demolished concrete waste selected is a combination of 20% of greater than 20mm aggregates,40% 20mm down aggregates and 40% dust with a CBR of 48% and qualifies for GSB–III and can replace the GSB layer in the pavement. The effect of demolished waste thickness as subbase layer on the overall strength of pavement considering only sub base and subgrade layers is determined.
