Realtime monitoring of bridge scour using remote monitoring technology

Description: Report on research performed on the application of instruments including accelerometers and tiltmeters to monitor bridge scour. The instrumentation on the two bridges does not show great hope of application of accelerometers to monitor bridge scour because of a lack of sufficient excitation from traffic. Tiltmeters can provide the integral behavior of the bridge, and therefore are very useful devices for scour monitoring. Guidelines and protocols for scour monitoring based on the US59 over Guad… more

Field and laboratory investigations for Full Depth Reclamation projects

Description: Full-depth reclamation (FDR) offers a timely, cost-effective solution to restore a pavement's condition. However, FDR represents only one technique in the engineer's toolkit available for addressing deteriorating pavement conditions. The purpose of this project is to provide guidance on determining whether a pavement is a candidate for FDR and, if so, what design, construction, and inspection processes will maximize the performance of the completed reclamation. This report presents initial reco… more
