Abstract
The quality of compaction is important to the performance of hot mixed asphalt (HMA) pavement. Most premature failures of asphalt pavement are the consequence of poor compaction. The process control method of compaction was studied here. The allowable compaction time of HMA pavement was estimated through field measurement and computer simulation. An instantaneous compaction procedure was recommended according the environment conditions and behaviors of compaction machines. The passing route of each roller was obtained using the global positioning system real-time kinematic technique. High quality compaction was achieved by controlling the operation of rollers. A pavement compaction process monitoring system was introduced to collect all the compaction information, such as the passing numbers of rollers, paving speed of pavers, and area of pavement not be compacted in time and so on. Alarm messages would be sent to roller operators, contractors, and managers when any improper operations occurred during compaction.
