Within the framework of our R&D collaborations and technology transfer, Sol Solution has equipped the expertise unit of the 25th Airfield Engineering Regiment with a complete system enabling it to deploy in the field a pavement inspection methodology. This solution developed by Sol Solution combines virtual coring and the use of the militarised Pandoscope®.

Virtual coring is a technique developed and patented by Sol Solution which consists in complementing or even substituting conventional coring of pavement structures by coupling the PANDA® penetration test and geo-endoscopy carried out on a very small diameter borehole (< 22mm). The image processing software and algorithms developed by Sol Solution's Research and Development allow to obtain a virtual core sample with a very high vertical and spatial resolution. Thus, it is possible to identify the thicknesses of each layer composing the structure, as well as their nature and their hydrous state, among others. This auscultation technique enables the structure manager to improve knowledge of his assets quickly and at low cost, without damaging the structural integrity of the structure and without disrupting the operation of the site (traffic, machinery circulation, etc.).

A team of 8 members of the 25th Airfield Engineering Regiment's expertise unit came to Riom at Sol Solution for 2 days of training. Experiments in the field and in test plots allowed us to transmit our know-how to the experts of our armed forces.

With some fifty expertise missions carried out each year, both in metropolitan France and abroad, the 25th Airfield Engineering Regiment's expertise unit, as part of its missions, diagnoses unpaved runways on rough terrain. It uses our auscultation techniques (Panda®, Pandito®, Kodiak® penetrometers, etc.) to collect input data for their work as forensic experts, but also for the dimensioning and evaluation of the bearing capacity of earth structures.
