A practical look at the factors that determine asphalt layer quality, from material selection to final compaction.
Material Selection
Asphalt layer quality starts with aggregate and asphalt binder compliance with approved project specifications, and with stable mix proportions within the designed mix.
Any deviation in gradation or asphalt content directly affects the layer's lifespan and resistance to deformation.
Temperatures & Execution
Controlling mix temperature during transport and paving is a decisive factor, as its drop affects compactability and surface uniformity.
Compaction & Testing
Target compaction density is achieved through a clear compaction plan, followed by field tests to verify that results match the specification.
