| 摘要： | The purpose of this report is to present findings from a two-stage investigation to develop a non-destructive system to evaluate critical properties and characteristics of asphalt pavements during the compaction process. The first stage aligned critical properties and characteristics with available non-destructive testing (NDT) technologies. A quantitative ranking was created with an objective and unbiased scoring system to determine the most appropriate NDTs for field evaluation. Based upon this ranking system, the three higher-ranked NDTs for the evaluation and selected for a field evaluation were: Infrared Thermography (IR), Ground Penetrating Radar (GPR), and Portable Seismic Pavement Analyzer (PSPA). The nuclear density gauge was also used in the evaluation. |
