Planning Minimizes Equipment Usage

A goal on any asphalt paving project should be to reduce the amount of equipment that is needed to complete the project. One obvious reason for reducing equipment utilization, from the contractor's viewpoint, is to decrease the owning and operating costs associated with the project. A second reason, and one that is becoming more of a requirement, is to reduce fuel consumption and the resulting emissions. A good example of how planning helped to reduce the size of the compaction train is work completed on rehabilitation of Interstate Route 88 (I-88) near Sidney, New York, USA, in 2009. The contractor calculated paving and compaction speeds and developed patterns to reach target density. Rolling patterns took into consideration the need to work ahead of tender zones. Cooling curves determined how much time was available prior to the onset of tenderness in each binder course and the wear course. The team verified that with proper planning, good communication, and execution, the compaction phase could be successfully completed with two vibratory, steel drum compactors. Total fuel savings for the project, based only on reduced compactor fleet, was roughly 12,000 litres. (A)
