Greenwood Engineering has developed ViscBackCalc, the world’s first online service capable of running visco-elastic back calculation on TSD measurements for precise prediction of pavement distress at network level.
It´s a very fast and easy way to calculate the structural properties of the road network.
ViscBackCalc allows users to upload TSD-measurements and apply visco-elastic back calculation to the entire chainage and download calculated fatique- and rutting strains, e-moduli and slopes. The service also allows for correlation to models derived from FWD. It also generates plots for deflections, slopes and strains and allows for temperature compensation and dynamic layer information e.g. from a ground penetrating radar. Reference benchmark for the combined calculation and data generation is 667 segments per minute#.
ViscBackCalc effectively calculates strains everywhere in the pavement structure from TSD measurements.
These strains are induced into the pavement by a driving truck, and they are therefore exactly what is needed to assess the pavement damage caused by ordinary truck traffic.
