GIRARDI MANCINI, Pablo  and  VICTOR CORDO, Oscar. Debris control proposals on National Route 40. Guillelmo-Bariloche Lake. Infraestructura Vial [online]. 2023, vol.25, n.44, pp.108-118. ISSN 2215-3705.  http://dx.doi.org/10.15517/iv.v25i44.53505.

In this paper are presented mass removal problems caused by excessive rains on National Road 40, San Carlos de Bariloche-El Bolsón section, in the southwest of the province of Río Negro, in Patagonia, Argentina, bordering Guillelmo Lake. The zone in question presents copious precipitations that affect hills, whose slopes have suffered forest fires, leaving them without vegetation and susceptible to erosion.

The aforementioned problems, obliged Vialidad Nacional to ask the School of Mountain Roads Engineering to solve this problem that is becoming chronic and whose severity increases with each climatic event. Actually, after each rain, large volumes of debris accumulate on the road, cutting the route and cutting off the link between the cities of San Carlos de Bariloche and El Bolsón, generating a great number of difficulties to the region. Firstly, procedures tending to alleviate this problem in the short term are proposed, as well as further actions to achieve a fundamental solution to solve this serious problem definitely.

Keywords : slope erosion; mass removal; debris flow control; slope stabilization.
