RES2023-28: Field Validation of Asphalt Pavement Density Using Ground Penetrating Radar
One of the final steps of evaluating the quality of asphalt pavement construction is measuring density of newly constructed pavement. The key to successful asphalt pavement construction is obtaining the desired density uniformly. Current construction and quality assurance procedures require measuring localized density with nuclear densometer or random core sampling from constructed pavement to measure density in the laboratory. This localized and random measuring may not represent the final quality of entire pavement when variations exist in density reading. OBJECTIVES: The primary objectives are as follows: Comparison of the accuracy and variability of the rolling density meter density data with existing density measurement procedures (nuclear density, coring, etc.); Evaluation of the reliability and ease of use of the rolling density meter; Evaluation of the mix design module to determine if the dielectric constant can be accurately determined from lab compacted asphalt specimens to eliminate the need for coring for calibration.
