Abstract:

The quality of finished Hot-Mix Asphalt (HMA) pavement is important to owners, contractors, and highway users. Primary factors affecting quality of HMA pavement are material properties, mix volumetrics, compaction energy, temperature, moisture content, thickness of mat, and subgrade support. A systems approach is necessary to control these multiple and often-changing factors during HMA construction operations in an effort to achieve a quality pavement. The framework is developed through a systems approach using currently available state-of-art technologies. These technologies arc comprehensively reviewed, and selected technologies are recommended for the future
