MS WIM – HIGH SPEED WEIGH-IN-MOTION SYSTEM
MS WIM – HIGH SPEED WEIGH-IN-MOTION SYSTEM
The installation of a Multiple Weigh-In-Motion Multiple-Sensor Weigh-Motion Sensor System (MS-WIM) on an Experimental Track was part of the LabTrans / UFSC and DNIT (TC 320 / 2010), with the aim of studying and monitoring the performance of different Wigh-In-Motion (WIM) systems technologies.
The focus of the project was to identify, evaluate and specify the WIM systems for weight control, as well as to analyze the behavior of the pavement in the tire / pavement interaction. In a 480-meter experimental track, built on the side track of the BR-101 (km 418), in the city of Araranguá / SC, 64 sensors were installed with 4 different types of technologies (quartz, ceramic, polymer and optical), strain, pressure, humidity and temperature sensors for the analysis of pavement deterioration.
As conclusion of the study, it was verified that the quartz sensors demonstrated a better performance for weighing in movement; and that the deformations obtained in the field have a close field-laboratory relationship obtained in the mechanistic laboratory tests of complex modulus and fatigue.
The products generated included: the methodology of specification and operational / economic evaluation; the methodology for identification and analysis of deterioration; and the follow-up for pre-selection with the use of MS-WIM.
