Pavement Instrumentation and WIM Data from a Test Track on the BR-101 Highway in South of Brazil
Usually, Brazilian highway are designed as flexible structures composed by one surface layer made of asphalt mixture (between 5 and 20 cm), one base layer with granular structure and one subbase layer composed by Macadam material. This type of structures is very sensitive to the traffic loads and specially with over-loaded vehicles. The use of WIM technologies on pavement depends of the pavement structure for performance and durability. Also, WIM data and pavement instrumentation allows the correlation between stress and strains on the pavement structure to predict its lifespan. The objective of this paper is to present a summary analysis of how to interpret the data from pavement instrumentation, installed on the pavement, and the effect of real heavy vehicles to pavement life. For this purpose, a 120 m test track was built designed as a thick asphalt pavement. The pavement structure is instrumented with 10 strain gauges (longitudinal, transversal and vertical alignment), 3 geophones, 6 temperature gauges, 2 piezopolymer and 2 piezoceramic WIM sensors. The presented analysis on this work combines a calibration campaign, using three types of truck axle configuration, and a real traffic data collection campaign. A pavement model built on ViscoRoute is then calibrated with information obtained during construction and from the data obtained with the set of sensors on the pavement. The final part of this work presents the evaluation of the effect of the real traffic loads and the effects on the pavement structure.
