1 Purpose of Testing

Entrusted by Yan'an Municipal Corporation, the three-dimensional radar detection of road quality on the non-motorized lanes of municipal highways in Yan'an New Area was carried out. The task of this inspection is to carry out ground penetrating radar reflected wave detection on municipal roads, with the purpose of understanding the distribution of road diseases and providing first-hand information for municipal road maintenance and repair.
