Focus Area




Comparative testing of equipment

Equipment testing involved:

•  Dynamic testing

•  Comparative tests

Evaluate forced dynamic loading of HVS MK IV+.

Compare results from HVS MK III to MK IV+.

Differences in the induced pavement response under the two HVS machines are small and of the magnitude of the variation normally associated with HVS testing

Differences in pavement response may be attributed to differences in load application frequency, actual applied load, tyre contact stress distributions.

Increased productivity of the HVS Mk IV+ compared to the HVS Mk III could result in a 50% increase in productivity.
