A Review Study of The Effect of Air Voids on Asphalt ...

2019-8-3  Asphalt without sufficient air entrapped in the layer will deform under traffic and result in a rutted and rough surface. Field air voids represent the amount of entrapped air in an asphalt layer that has been placed on-site. The objective of asphalt mix design is to achieve an asphalt mix with the lowest practicable air voids without compromising
