This group were presented about the materials used in Highway. We learnt that there are few layers before the highways were made. The first layer of the highway is Subgrade, the second layer is sub base & the third one is base. We also learnt that different layer were used with different types of materials. For subgrade, we use Soil. Secondly, for the sub base we use fine aggregate. Lastly, we use coarse aggregate for the base. With the help of our lecturer, Encik SaifulBahri, we gained new knowledge of this topic which is the constructions of highways.
