GPR survey of Voronezh runway was performed with the aim to determine structural layers thickness and to discover structural abnormal areas till the top of the natural bed.
GPR OKO-2 with antenna units AB-1700 and AB-400 were used for the survey:
- AB-1700 provides for investigating the section to 0.6-0.8m depth, indicating rather thin layers of 3-5 cm. This antenna unit was used to determine asphalt concrete upper layer and cement concrete underlayer thickness.
- AB-400 features investigation depth up to 3-4 m and was used to study bottom soils.
