Modeling the volumetric properties of asphalt concrete with the aid of NDT

Author(s): Saad Issa Sarsam, Nazar Sajad Kadhim
Abstract: Construction of Asphalt Concrete is accompanied by intensive quality control testing process. Implementation of such testing process is labor, time and budget consuming. It was felt that the nondestructive testing NDT can overcome such issue, while modeling the relationship of volumetric properties of asphalt concrete with ultrasonic pulse velocity UPV is a probable quick check process in the field giving an idea to the field Engineer about the quality of the pavement. In this investigation, asphalt concrete specimens have been prepared in the laboratory and subjected to volumetric properties determination using the standard Marshal Test procedure. Specimens have also practiced ultrasonic pulse velocity test using Pundit instrument. Test results were analyzed and modeled. A nonlinear statistical model relating ultrasonic pulse velocity with the volumetric properties of asphalt concrete was obtained. It was concluded that such model can explain 93.7 % of the variation in the volumetric properties under the testing techniques implemented.
