Validating Density Profiling Systems (DPS) for Asphalt Compaction Assessment
Project Information
Project ID:
FHWA-PROJ-19-0087
Project Abstract:
Validating Density Profiling Systems (DPS) for Asphalt Compaction Assessment: As the DPS technology needs to be proven as a tool for quality assurance of asphalt compaction, the measured values of dielectric should be accurately converted to the pavement properties related value (percent air voids - Va%). Therefore, the scope of this research is to evaluate the development of DPS data collection protocols by assessing:
- Aggregate type, size (NMAS) and distribution (gradation) effects
- Binder type effects
- Number of data collection passes needed to assess compaction quality of the full lane width
- Data collection pattern, speed and location based on different construction traffic control methods
- Evaluate equipment requirements
