Large amounts of collected deflection data and parameters as E-moduli and strains are easily analyzed with the visco-elastic back calculation TSD-software. When the full picture is known for every part of the road network, it is possible to plan pavement maintenance without any unknowns and to use maintenance funds in a truly smart way.
SCITSD is the NEW structural curvature index for strain analysis of large road networks and airfields developed by Greenwood Engineering. It is well suited for rolling wheel deflection (RWD) experiments as performed by the Traffic Speed Deflectometer.
SCITSD vs. tensile strain at the bottom of the top layer. SCITSD is proportional to the strain, since they are both derived from the curvature of the deflection bowl, this means that the tensile strain can be calculated directly from SCITSD shown as the green curve.
