[ 1 ] - Control of Engineering Properties of Asphalt Concrete Based on Permanent Deformation Constraint of Subgrade at Tropical Zones in Iran (TECHNICAL NOTE)

The permanent deformation pavement of roads and streets at tropical zones Abstract (if layers are sufficiently compacted) is due to increase of asphalt layers temperature and consequential decrease of modulus of elasticity. Therefore, the asphalt mixture moves aside of the wheels of heavy vehicles and cause permanent deformations without volume variation. On the other hand, if the asphalt layer...
