The affected stretch of the road and the breakwater are located in the Mediterranean coast, in an area where the motorway V-21 lays parallel and extremely near to the coastline, in a suburban stretch [...]

IP0223 - IMPROVEMENT OF THE WATERCOURSE AND ROAD INFRASTRUCTURE AT THE CROSSING OF N 232 ROAD OVER RAVINE MOLINÁS IN XERT (SPAIN) (.pdf - 5Ko)

This paper tries to explain the adaptation of an existing crossing over a ravine in the Mediterranean area of Spain. Existing infrastructure comprises road N 232 (two lanes, one each traffic direction) including a former bridge from around 1940 (only for local transit) and a new one from 2002 (main long distance transit). Water only flows after certain rain episodes, but commonly is a dry course. [...]

IP0314 - Strategies for geotechnical adaptation and resilience of Kamchik pass. (.pdf - 13.5Mo)

This communication presents the case study of the Tashkent - Osh corridor in its transit through the Kamchik pass in eastern Uzbekistan, a mountain highway that has been part, for centuries, of the so-called Route of the Silk. This transport infrastructure is of strategic importance both locally, since it is the only road that connects the Fergana valley with the rest of the Uzbek national territory, [...]

IP0335 - Harmonizing Resilience in Asset Management, Data Registration and Hydraulic Design of Road Culverts in Norway (.pdf - 115Ko)

Effective asset management strategies for road drainage depend on both effective data registration and a rational understanding of the physical operation of the assets in questions. Differences in practice and working definitions between these fields can hinder the value-realization of the management strategies. The present paper considers the impacts of climate change on road culvert operation, and [...]

IP0267 - GEOTENIC INFRASTRUCTURE OBSERVATION AND HEALTH MONITORING MANUAL (.pdf - 2.4Mo)

In the context of the integrity and management of road geotechnical infrastructures, ASCENDI assume as guidelines during the Operation and Maintenance period the prevention and safety of users, which in turn implies the constant control of their maintenance and conservation states. In order to achive these goals, we use innovative observation and health monitoring methodologies of the Walls & Slopes [...]

IP0186 - Case Study on Damage and Restoration of Mechanically Stabilized Earth Walls Due to Deicing Agent (.pdf - 1.0Mo)

In Korea, reinforced earth retaining wall was introduced in the 1980, it is widely used because of constructability, economics, and beauty compared to existing concrete retaining wall. About 700 reinforced earth retaining walls were constructed on expressway site and about 10% of constructed reinforced earth retaining walls were managed by the “Special Act on the Safety Management of Facilities” [...]

Ce document présente et analyse certaines des dernières expériences, applications et projets de recherche liés à l'augmentation de la résilience et de la durabilité du réseau routier de l'État dans le nord de l'Espagne. Les principales actions menées pour adapter les routes aux effets du changement climatique ont été la conséquence des dommages causés par les pluies torrentielles et [...]

IP0246 - Action sur le drainage et les structures de terre pour éviter l'effondrement des infrastructures ferroviaires croisant l'autoroute (.pdf - 111Ko)

The purpose of this paper is to describe the emergency action carried out for ADIF (Administrador de Infraestructura Ferroviaria) in the first half of 2019 to prevent the collapse of the railway infrastructure between KP 487+230 and KP 488+600, on the Reguerón-Riquelme route, Chinchilla-Cartagena line. Due to the heavy rainfall at the end of 2018. This line intersects the Santomera-San Javier highway, [...]

IP0274 - Gestion de l'aléa rocheux sur la RN1 à la Réunion : de la gestion de la circulation et des travaux de protection à un nouveau tracé (.pdf - 6.9Mo)

RN1 on Reunion Island is a strategic road infrastructure linking the port to the departmental headquarters; over 12 km long it is dominated by a cliff almost 200 m high. Supporting a traffic of 60,000 vehicles / day, it is also subject to significant daily traffic jams on arrival at St Denis, which lead to long wait times under the cliff. Securing this route is a major concern for its successive managers. [...]

IP0381 - Gestion du risque lié aux cavités souterraines « Phénomène de dissolution de gypse » (.pdf - 1.5Mo)

Au cours des travaux d’exécution de l’autoroute A3 : TUNIS - MEJEZ EL BAB, il a été découvert des cavités souterraines liées au phénomène de dissolution du gypse de la formation de Trias reconnue sur plus de 40m de profondeur et sur un tronçon de 3km. Le risque réel et majeur lié à la présence de ces cavités sous la plate-forme autoroutière est l’apparition subite de crevasses [...]

IP0269 - RÉSILIENCE CLIMATIQUE DANS LE SECTEUR ROUTIER AU MOZAMBIQUE (.pdf - 231Ko)

Title: Analysis of resilient roads in the rainy season 2020/2021 Mozambique is a coastal country consisting of relief in the form of a staircase that decreases in altitude as we move from the interior to the coast region.

Resilience of road infrastructure to geohazards is often addressed through strengthening resistance incurring significant costs. The effects of climate change will, in many places and for various landslide types, lead to a hazard increase. Consequently, building stronger infrastructure at high costs will become less effective. This case study presents an alternative intervention approach by Parks [...]
