Asphalt concrete roads are susceptible to deterioration over time due to factors such as wealthering, traffic loads, and environmental conditions. Premature cracking, rutting, and surface distress can lead to increased maintenance costs and reduced road service life. By conducting a thorough investigation into the key properties of asphalt concrete, this research aims to provide insights that will contribute to the development of optimized mix designs and construction practices, ultimately leading to more durable, safe and sustainable road infrastructure. A series of test was carried out including the marshal test to check asphalt mix design, proportion aggregate and asphalt materials for pavement construction.Penetration test was also carried out to to measure of consistency, hardness or softness of bitumen been used. From the test carried out, it is suggested that asphalts materials of high stability and stiffness should be used, as this reduces the shear deformation of roadswhich is a major failure of asphalt pavement. It was also noted that the asphalt concrete must be strong enough to withstand the stress transmitted to it.
