Intelligent Compaction (IC)

The Intelligent Compaction method involves compaction using an instrumented roller; a self-propelled roller integrated with a global navigation satellite system and onboard documentation system that can display real-time color-coded maps of roller location, number of passes, roller speeds, and amplitude and vibration frequencies of the roller drum.

Intelligent Compaction is used to assist with:

  • Optimizing compaction efficiency
  • Achieving uniform compaction and surface coverage
  • Identifying weak spots
  • Identifying non-compactable area

Paver Mounted Thermal Profiling (PMTP)

The Paver Mounted Thermal Profiling method uses a continuous monitoring system that provides readings of the surface temperature of the mat immediately behind the paver screed during placement operations to assist with determining temperature segregation.
