    Limestone is used in many countries for road pavement, such as Poland, USA and France. However, there are limitations in terms of mechanical and surface properties, but it has been used in some regions for years, particularly in Perlis, Malaysia, due to the need for a local source. The reason is that of caution of fear, in spite of wanting to explore the opportunities of Perlis limestone being used and understand the advantages and disadvantages of that aggregate. This study focused on the stability, flow, and volumetric by using a combination of Perlis limestone and granite in hot mixed asphalt (HMA) mixtures. The combination of Perlis Limestone and granite was analysed and tested to specification for roadworks by PWD, Malaysia. Furthermore, there will be a cost increment in road construction due to logistic and transportation problems in delivering imported granite aggregate from Kedah state. The result showed that HMA with less Perlis limestone aggregate showed a higher value of stability, flow and stiffness. As for the conclusion, HMA with more granite aggregate has better strength with less deformation compared with HMA with more Perlis limestone aggregate. HMA with more granite aggregate was also was stiffer, mainly due to the interlocking and frictional resistance of the aggregate due to the angularity and rougher surface of granite. However, since all the samples complied with the PWD specification, Perlis limestone proved it can be an alternative aggregate to be used in HMA.

    The concrete structures that are built along the seaside often suffer from reduced service life due to inadequate durability against deterioration. This research reports the findings of concrete resistivity and quality using two Non-Destructive Testing (NDT) measures applied to Reinforced Geopolymer and Ordinary Portland Cement (OPC) concrete in the marine environment. In addition, the relationship between Reinforced Geopolymer and Reinforced OPC concrete was statistically discussed in-terms of strength and direction. The testing was carried out using a Proceeq Resipod Wenner 4-probe to measure Surface Resistivity (SR) and Ultrasonic Pulse Velocity (UPV), respectively. The testings were carried out on beam shaped samples of OPC and Geopolymer concrete that were immersed in seawater over a period of 90 days with similar curing condition. It was found from the present investigation that the maximum SR and maximum UPV values acquired for both the Reinforced OPC and Reinforced Geopolymer concrete are 2.73 kΩcm and 2.07 kΩcm, as well as 4.18 km/s and 4.05 km/s, respectively. It is apparent from the study that both concrete is comparable in terms of quality and surface resistivity.

    The most important component of road construction is aggregate. As 70-80 percent of aggregates are used in road construction, the majority of aggregates used in Malaysia's road construction are granite aggregates. Due to the lack of substitutes for aggregates and the rise in demand, this may hinder the development of the road construction process. This research seeks to identify high-quality alternatives to granite aggregate that can be utilised to their full potential. Since there is no granite in Perlis, Malaysia, the mechanical properties of the Perlis limestone aggregates were evaluated to ensure that they can be used alone or in combination with granite aggregates in road construction. The AIV, ACV, and LAA tests were conducted on both individual samples of Perlis limestone and granite aggregate, as well as combinations containing various percentages of each. In all tested parameters, the results indicated that Perlis limestone aggregates were superior to granite aggregates. In addition, when Perlis limestone and granite were combined in an unbound state with the presence of limestone, the strength and resistance to abrasion and impact increased linearly. It is believed that incorporating Perlis limestone into unbound layers of road construction, such as roadbase and subbase, will enhance their performance.
