The Correlation between Compaction Degree and Performance Life of Asphalt Concrete

Inadequate compaction of wearing course of asphalt concrete is a common phenomenon in road construction. Contractors choose to apply a minimum compaction effort in order to cut costs and speed up construction process. Even though the requirement set by relevant authorities such as, Jabatan Kerja...
