Consulting on GPR Systems
Roadscanners provides consulting to road owners and survey providers in adopting GPR techniques as a part of their state-of-art road survey system. Our consulting services range from general consulting and pilot projects to testing the benefits of GPR techniques on local survey objects, to turnkey deliveries of total GPR survey systems.
Case: Turnkey System Delivery to Technical Center of Estonian Roads
The delivery of a GPR-based road survey system for the Technical Center of Estonian Roads in year 2000 was a large-scale project, including
-
equipping the client's measurement van with an SIR-10 H GPR unit and three antennas for different survey tasks, a video recording system, and a reference drill;
-
delivery of Road Doctor ™ software for the processing and interpretation of survey results; and
-
training of the operating personnel, in three periods following delivery, first in the theory of GPR measurements and methods of application, and subsequently using the new equipment and software in practice involving various survey tasks.
Case: Queensland Department of Main Roads
In March 2001, Roadscanners was contracted by the Queensland Department of Main Roads to consult on a GPR trial in Queensland, which focused on testing the use of the latest GPR technology and software in pavement investigations. The assignment included lectures on the applications of GPR in road surveys, and especially in pavement investigations, guidance on data collection, and analysis of the trial survey results.
Case: Consulting TTI in the Use of Ground-Coupled GPR Antennas in Road Surveys
The Texas GPR´99 Project included research on GPR applications for road damage analysis and subgrade quality assessment on test sections on FM 2446, FM 488, and the Old Spanish Road in Texas, as well as the training of personnel at the Texas Transportation Institute in ground coupled antenna survey techniques and data processing.
Case: Testing GPR Applications for Minnesota Department of Transportation
During May 1998, Roadscanners together with the Office of Minnesota Road Research performed a series of GPR tests in Minnesota, in order to determine the level of accuracy of the GPR technology in pavement and subgrade soil testing. The project involved a total of 195 km of GPR surveys carried out in different locations throughout Minnesota. The test sections represented a range of pavement materials, structures and soils found in the state. A number of GPR tests were performed to evaluate different types of pavement defects and ascertain their causes.
The results of the Minnesota GPR Project 1998 clearly demonstrate the benefits that GPR techniques offer and that GPR can be applied in measuring the layer thickness of various pavement structures. The surveys also revealed some previously unknown defects in the test cells, such as stripping, voids, and moisture anomalies.
