ABSTRACT

The article presents design methods and execution technologies for consolidating geotechnical structures and roads in mountains areas of Romania, considering the specific conditions for each site. The design process took into consideration the difficult site conditions respectively, the working space - the consolidation and drainage works must be strictly performed within the road area (approximately 9m wide) and the execution phases – the works must be executed in such a way that traffic can proceed safely. The paper will present several situations encountered in different locations in Romania, with their respective geotechnical and hydrogeological characteristics and the specific technical solutions chosen at the design stage and implemented throughout the execution. Detailed solutions will be offered for the drainage system and the surface and underground water, as well as for the restoration of existing structures. The degradation over time of the road-associated structures is a widespread problem and it is influenced, among others, by geotechnical conditions and water action. Such deterioration compromises traffic safety leading to partial failure with impact to the usual traffic and even to complete failure. The pressing need for safety usually demands an emergency intervention plan, with technical solutions that can be quickly executed in the event of a major hazard. With this innovative approach, roads can be made safer and more resilient against future deterioration caused by changing geotechnical conditions or other environmental factors.
