NON-DESTRUCTIVE IN-SITU MEASUREMENT OF THE THICKNESS AND DENSITY OF REINSTATEMENTS

The work described in this paper is part of a research programme commissioned by the UK Water Industry Research Ltd (UKWIRL) to provide the Water Industry with guidance relating to non-destructive methods of in-situ measurement of the thickness and density of permanent bituminous reinstatement layers. The specific objectives of the project were: to identify non-destructive test (NDT) equipment and techniques currently available for the in-situ evaluation of the density or thickness of highway reinstatements; to establish whether there is any potential for developing innovative technologies not currently in use; to establish what destructive and NDT equipment are currently used by the Water Industry; to carry out a technical evaluation of NDT techniques thought to be potentially of use; and to compare costs and potential benefits to establish whether any NDT techniques identified are financially viable compared with conventional destructive methods.
