National road no. 7 (DN7) is one of the most important routes through the Carpathian Mountains, with heavy traffic. The Olt River runs parallel to the DN7 with high mountains, directly next to the road. In winter and spring rockfalls occur regularly. Also with unstable slopes, torrents and avalanches the risk of accidents was high.
This project was originally developed with five concrete canopies for rockfall protection. Due to costs and other restrictions, a modern solution using high tensile steel wire was chosen. After further investigation, 23 dangerous areas were found and had to be protected using two types of protection systems: active and passive.
As passive protection measures, AXI and RXI rockfall barriers with dynamic capacity ranging from 500 to 3000 kJ were chosen for the following sectors:
1. km 198+523.72 - 198+571.00
2. km 200+166 - 200+193
3. km 200+207 - 200+219
4. km 201+384 - 200+427
5. km 206+004 - 206+034
RXI-100 and RXI-300
