GPR Monitoring of Artificial Debonded Pavement Structures throughout Its Life Cycle during Accelerated Pavement Testing

GPR Monitoring System for Evaluation of Asphalt Pavement

To evaluate the condition of asphalt pavement road, two GPR systems with different frequency band were mounted in the trailer type vehicle. The GPR system with higher frequency band was used to measure the thickness of the asphalt layers and the other system with lower frequency band was used to detect the air cavity located beneath the asphalt pavement.

Full-Scale/Accelerated Pavement Testing: Current Status and Future Directions

Full-scale and accelerated pavement testing (FS/APT) began as early as 1909 with a test track in Detroit, as identified by Metcalf in NCHRP Synthesis of Highway Practice 235: Application of Full-Scale Accelerated Pavement Testing (1). Various other facilities have been developed and used worldwide to pursue this activity, defined in NCHRP Synthesis 235 as " the controlled application of a proto...

Optical fiber feasibility study in Accelerated Pavement Testing facility

The presented research has been carried out within the European project Intelligent Roads (INTRO). The major objective followed was to assess the potential of optical fiber for pavement monitoring in comparison with classical strain gauges. Thus, both measurement devices have been tested under the same conditions in a full scale Accelerated Pavement Testing (APT) at LAVOC. This facility allows ...

High Modulus Pavement Design Using Accelerated Loading Testing (alt)

In anticipation of the introduction of high modulus materials in the Swiss standards, a research project has been carried out for the evaluation of these bituminous mixtures. Three full-size test sections were built in a test hall for ALT named Halle-fosse: Two sections with two different high modulus bituminous mixtures (named EME, abbreviation of the French designation of the mixture: Enrobé ...
