“…General GPR applications on roads and streets can be divided roughly into four main categories: (1) surveys carried out in design of a new road, (2) surveys needed for the rehabilitation design of an existing road, (3) quality control or quality assurance surveys on a road project and (4) surveys for pavement management systems and similar purposes (see Saarenketo, 1992;Fernando et al, 1994;Hugenschmidt et al, 1996;Scullion and Saarenketo, 1998;Saarenketo and Scullion, 2000;Saarenketo, 2001;Scullion, 2001;Maser, 2002a,b;Ahmed et al, 2003;Al-Qadi et al, 2003c;Johansson et al, 2005).

Ground penetrating radar for road engineering

“…Thus, traffic flow obstruction can be kept to a minimum. A detailed description of typical acquisition parameters is given in [2].…”

Effect of the height of the observation line on the the diffraction curve in GPR prospecting

“…In many other cases, the permittivity is the key factor to achieve a correct time‐depth conversion and affects crucially the data processing for buried targets characterization via migration or inversion approaches (Stolt ; Schneider ; Persico ). This has significant impact in many application as pipe detection (Graf ), archaeological prospecting and monitoring of historical buildings (Persico et al ; Utsi ; Gabellone et al ; Barone et al ), pavement monitoring (Hugenschmidt et al ) and possibly demining (Sato and Takahashi ). Most of the times, contact data are gathered, but in some cases the time required (Hugenschmidt et al ), the lack of permissions (Bradford et al ), the risk of damaging a work of art (Pieraccini et al ) or the intrinsic danger of a contact measure (Sato and Takahashi ) prevent from taking contact data, even if this has some cost in terms of reconstruction performance especially with regard to the resolution limits (Persico ).…”
