Preliminary comparison of an electro-mechanical method with other in-situ strength measuring devices

Road AB Considerable effort is being devoted to the development of non- destructive pavement structural evaluation tools. In particular, tools that measure fundamental engineering properties as opposed to empirical measures. A recent addition to the fold is the Humboldt GeoGauge, hereafter referred to as the GeoGauge. The University of Auckland and Geotechnics Limited have initiated a joint study to assess its suitability for application in New Zealand. Extensive research into the capabilities of the GeoGauge has been carried out in North America. Although currently at the desk study phase some preliminary testing has been carried out to assess the operational aspects of the equipment in the field, as well as providing some limited comparisons with other related technologies. This paper will therefore provide an introduction to the GeoGauge and other related technologies, describe some of the comparative studies carried out to date, analyse the results and, finally, provide some tentative recommendations for its use.(a) For the covering entry of this conference, please see ITRD abstract no.
