    The rapidly increasing in population has led to the higher of construction, repairing and renovation activity that lead to produce large amount of construction material waste. The disposal of broken ceramic tiles during construction is one of the factors which contribute to this matter and can lead to land pollution. On the other hand, the natural resource in construction such as fine aggregate also facing depletion in order to cater the current and future demand. Therefore, this paper explores the properties of concrete with ceramic tile waste used as a partial replacement for fine aggregate. About 45 cube samples, 30 prism samples and 15 control samples were casted. Various percentage of ceramic tile waste has been introduced as partial replacement for fine aggregate with proportion of 10%, 15%, 20% and 30%. Tests for mechanical and rheological properties which have been done to identify the concrete performance are compressive strength, flexural, water absorption and slump test. From the results obtained, the sample of concrete contain of 15% ceramic tile waste as fine aggregate replacement has reached the optimum strength in both compressive strength and flexural strength. However, by using 20% of ceramic tile waste as fine aggregate replacement does show higher workability and water absorption.

    Reducing dependent on naturally sourced materials is among the priority in improving the sustainability of road construction. The subbase layer which provides strength and stability across the road profile, comprised mainly of natural aggregates. This study aims to explore the feasibility of partial replacement of natural aggregates in subbase layer with 20% Crushed Brick (CB) and 20 to 50% Reclaimed Asphalt Pavement (RAP). California Bearing Ratio (CBR) test and Constant Head Permeability tests were carried out to determine the effect of this partial replacement on the geotechnical properties of the subbase layer. The results obtained denotes that the combination of 20% CB and 50% RAP is the optimum partial replacement of natural aggregates in subbase layer with CB and RAP. The use of CB further complements RAP in improving the stiffness and compressibility of the subbase layer while contributing significantly toward sustainability in road construction.
