Title: VOID DETECTION FOR JOINTED CONCRETE PAVEMENTS
Accession Number: 00458109
Record Type: Component
Availability: Find a library where document is available Abstract: Procedures for the detection of voids or loss of support under jointed concrete pavements by using nondestructive deflection testing measurements are presented. A rapid field-applicable procedure is presented to quickly determine the presence of voids by analysis of the load and deflection response at slab corners. A more detailed method is presented in which deflection measurements from center slab and corner locations are used to locate and determine the approximate size of any existing voids. The procedures were developed by using computer modeling of loadings with the ILLISLAB finite-element computer program. The procedures were field verified on several test projects. Basic guidelines for testing, locating joints or cracks requiring subsealing, and estimating grout quantities for jointed concrete pavements are presented.
