  • IP0222 - Adaptation of a shoreline and motorway protection breakwater in Valencia (Spain)
    Vicente Dueñas Jerónimo

    This paper tries to explain the adaptation of an existing breakwater designed for the protection of the shoreline and the adjacent motorway V-21, in the surroundings of the city of Valencia, in Spain. 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 [...]

  • IP0186 - Case Study on Damage and Restoration of Mechanically Stabilized Earth Walls Due to Deicing Agent
    Nam Moon S.

    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” [...]

  • IP0269 - CLIMATE RESILIENCE IN THE ROAD SECTOR IN MOZAMBIQUE.
    Mascarenhas Iracema

    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. The hydrographic network consists of rivers that run west to east and nine of them are born in neighboring countries, this fact contributes to the registration of frequent floods [...]

  • IP0246 - Drainage and earth structures to prevent the collapse of the railway infrastructure intersecting with the highway
    DÍAZ GARCÍA ANTONIO JESÚS

    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, [...]

  • IP0204 - Embankment slope protection project type selection on post-disaster recoverability
    HE XINYUAN

    Abstract: This article introduces the types and scope of slope protection works commonly used in China's highways. Data shows that 1/3 of the damage to highways caused by natural disasters is caused by slope instability. This article, through case studies, illustrates the great significance to improving the road disaster resilience and recovery, by correct choose of protection works type, improving [...]

  • IP0290 - Emergency on the road GR-3417 and Granada Metro Platform at the cross over Juncaril brook, between Albolote and Maracena (Spain)
    Herrador Rosario

    On January 2020, after heavy rain falls, there was a located collapse on the embankment nearest to the cross-drainage work that gives way to Juncaril brook, between Maracena and Albolote (Granada-Spain). Over this drainage work runs the road GR-3417, depending on Council of Granada (Diputación de Granada). This is a two directions road between which runs Granada Metropolitan platform, depending on [...]

  • IP0267 - GEOTENIC INFRASTRUCTURE OBSERVATION AND HEALTH MONITORING MANUAL
    Ferreira Alexandra

    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 [...]

  • IP0335 - Harmonizing Resilience in Asset Management, Data Registration and Hydraulic Design of Road Culverts in Norway
    Sellevold Joakim

    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 [...]

  • IP0223 - IMPROVEMENT OF THE WATERCOURSE AND ROAD INFRASTRUCTURE AT THE CROSSING OF N 232 ROAD OVER RAVINE MOLINÁS IN XERT (SPAIN)
    Parrilla Alcaide Álvaro

    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. [...]

  • IP0368 - INCREASING RESILIENCE OF EARTH STRUCTURES ON ROAD OF NORTHERN SPAIN. LESSONS LEARNED IN THE PERIOD 2011-2018
    COLLAZOS-ARIAS FELIPE

    This paper presents and evaluates some of the most recent experiences and research projects related to increasing resilience and sustainability on roads of northern Spain. The most remarkable actions carried out to adapt the roads to the effects of climate change have been due to the need to respond to extreme weather events occured during Winter seasons. From 2011 to 2018, cantabrian roads suffered [...]

  • IP0381 - Risk management related to underground cavities "Gypsum dissolution phenomenon"
    ZAGHOUANI KAMEL

    During the execution works of the A3 motorway: TUNIS - MEJEZ EL BAB, it was discovered underground cavities linked to gypsum dissolution phenomenon. the site presents a sensitive area, an important tectonic movement and a heavy rain. The real and major risk is related to cavities under the highway platform and the progressive behavior of gypsum dissolution. The treatment of these cavities was by filling [...]

  • IP0274 - Rock Hazard Management of the RN1 in Reunion Island: from circulation management, protections works to a new route
    AZEMARD PIERRE

    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. [...]

  • IP0314 - Strategies for geotechnical adaptation and resilience of Kamchik pass.
    Joaquin Perez-Romero

    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, [...]

  • IP0102 - TREAT THE SOURCE, NOT THE SYMPTOMS – INVESTING IN UPSLOPE DEBRIS-FLOW MITIGATION AT EAST GATE LANDSLIDE (TRANS-CANADA HIGHWAY)
    Busslinger Matthias

    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 [...]
