Abstract
Conventional rolling equipment, such as steel vibratory rollers, while capable of achieving a specified density, results in construction induced cracks. These cracks are often visually apparent, and they are due to a mismatch between the geometry and relative rigidity of the roller and the asphalt mix. Asphalt Multi Integrated Roller (AMIR) was developed to compact asphalt and to prevent the surface cracking of pavement. AMIR was developed by replacing the cylindrical stiff shape with a moving flat softer plate which results in a crack free asphalt layer and more uniform compaction along and across the mat.
