    The effects of supplementary cementitious materials (SCM) on the characteristics and internal structure of synthetic aggregate made from ground granulated blast furnace slag are investigated in this study (GGBS). Due to its high pozzolanic activity, GGBS was shown to be superior to other SCM materials, enhancing both the strength and durability of synthetic aggregate. Because sintering uses a lot of energy and generates a lot of pollutants, using a cold-bonded approach to make low density lightweight aggregates is particularly significant from an economic and environmental standpoint. Thus, the utilisation of ground granulated blast furnace slag (GGBS) as a substitute material in the production of green artificial lightweight aggregate (GLA) using the cold bonding method was discussed in this work. Admixtures of ADVA Cast 203 and Hydrogen Peroxide were utilised to improve the quality of GLA at various molar ratios. The freshly extracted GLA was then evaluated for specific gravity, water absorption, aggregate impact, and aggregate crushing in order to determine the optimal proportion blend. As a result, the overall findings offer great application potential in the development of concrete (GCLA). It has been determined that aggregates with a toughness of 14.6% and a hardness of 15.9% are robust. The compressive strength test found that the GCLA has a high strength lightweight concrete of 37.19 MPa and a density of 1845.74 kg/m3. The porous features developed inside the internal structure of GLA have led to GCLA’s less weight compared to conventional concrete.

    Palm kernel shell (PKS) is known as a waste material that produced by oil palm factory. In this research, PKS will be used as an alternative to improve the strength and performance of hot mix asphalt (HMA). The bitumen grade of 60/70 PEN and ACW14 had been used in the research. To investigate the strength of PKS in term of designing wearing course, bitumen content of 4% to 6% and different mix design with different percentages content of PKS were provided. The total specimens prepared in this research are 45 specimens. The specific gravity of PKS was lower and showed the high capacity in water absorption compare to the natural aggregate. The increment of percentage for PKS in HMA make the strength in Marshall Specimen became decreases as stated in the result and discussion. Result of optimum bitumen content for PKS 10, PKS 30 and PKS 50 were 4.72%, 4.86% and 4.90% individually. All optimum bitumen content in this research was satisfied with JKR Standard 2008 in term of the design parameter. The specimen of PKS 10, PKS 30 was classified as heavy traffic and PKS 50 was classified as medium traffic. PKS 10 was shown as a good partial replacement for natural aggregate due to the admissibility of parameter, environmental friendly factor and cheapest in costing.
