The use of the benkelman beam in Queensland

The benkelman beam has been used principally on a limited basis to measure the deflection of pavements as an aid in the investigation of distressed pavements and as such has proved a useful tool. An examination of these results gives a tentative criterion for the deflection of "suspect" pavements. Any pavement not having a mean less than 40.0 Should be regarded as "suspect" and likely to need early maintenance. No correlation has yet been established between deflection and the "additional corrective pavement thickness" necessary to reduce that deflection to within acceptable limits. A brief report is made of deflection data for an as yet unopened road designed to a minimum pavement thickness; further data will be collected at appropriate intervals to observe seasonal variations and permanent changes in performance throughout the life of this road (a).
