Abstract: The volume of waste generated in Malaysia and throughout the globe continues to increase. Waste management and protection of the environment should be given a priority, and this requires for studied to be carried out on the problem of waste management. One of the approaches that can be adopted in this regard is to reuse waste materials as recycled products. Mechanical and geotechnical tests, namely the Los Angeles abrasion tests, the Atterberg limit test, and the sand equivalent value, were carried out to determine the suitability of using steel slag and CRT glass in the construction of road pavements. The value obtained from the laboratory test is within the JKR standard specification (JKR/SPJ/2008-S4). The objective of this study is to investigate the mechanical and geotechnical properties of steel slag and cathode ray tube (CRT) glass in order to determine the feasibility of using both materials as a natural aggregate replacement in the construction of road pavements. The result for the Los Angeles abrasion test showed that steel slag has better wear resistance and mechanical properties compared to those of the natural aggregates (granite) use in this study. The result for the Atterberg limit test showed that all three samples (granite, steel slag and CRT glass) are non-plastic. While the result for the sand equivalent value test showed that the granite sample has the highest value, followed by CRT glass and steel slag. Thus, it can be concluded that steel slag and CRT glass are suitable substitutes for natural aggregates (granites) since they have been proven to meet the requirements for the natural aggregates with similar properties. This provides an alternative use for recycled materials and the possibility of using these materials as an aggregate replacement in the construction of road pavements.
