The Texas State Department of Highways and Public Transportation has 13 falling weight deflectometers to obtain deflection information for the Pavement Management System, determine optimum rehabilitation and reconstruction strategies for highway segments, design new pavements and overlays, establish load restrictions on light pavements, and to determine wheel load capacity of pavements for superheavy permit moves. SDHPT has developed procedures to utilize FWD in the determination of elastic moduli of paving materials for design and evaluation on both rigid and flexible pavements. Special equipment is used with each FWD to perform load transfer surveys across joints and cracks on rigid pavements. A microcomputer program called MODULUS was developed to backcalculate pavement layer moduli using FWD or dynaflect deflections. Pavement design and overlay thickness determination is also accomplished with a microcomputer program. The network level deflection test surveys of its highway system performed by SDHPT is described.
