NATIONAL ROAD 19. THE PROVINS DIVERSION. CONSTRUCTION OF THE RN 19 DIVERSION IN PROVINS. DIFFICULTIES AND LESSONS LEARNT FROM THE CROSSING OF A PEATY VALLEY

RN 19 - DEVIATION DE PROVINS - LA REALISATION DE LA DEVIATION DE LA RN 19 A PROVINS - DIFFICULTES ET ENSEIGNEMENTS DUS AU FRANCHISSEMENT D'UNE VALLEE TOURBEUSE

THE FIRST ARTICLE DESCRIBES IN DETAIL THE GEOTECHNICAL PROBLEMS ARISING FROM THE CROSSING OF THE PEATY VALLEY, THE VARIOUS SOLUTIONS PUT FORWARD AND THE FINAL ONE ADOPTED: LOWERING OF THE LONGITUDINAL PROFILE. STUDIES CONDUCTED BY THE "LABORATOIRE DE L'EST PARISIEN" FOR SOLVING DIFFICULT PROBLEMS OF SOIL MECHANICS COULD BE USEFUL TO CONTRACTORS FACED WITH SIMILAR CONDITIONS, E.G., STABILIZATION OF THE EMBANKMENT WITHOUT DELAY TO THE OPENING OF THE DIVERSION TO TRAFFIC. EARTHWORKS EXCEEDED THE FORECASTS BY 20%, AND ENGINEERING STRUCTURES GAVE RISE TO FOUNDATION PROBLEMS. DETAILS ARE GIVEN OF THE VARIOUS CONSTRUCTION STAGES: EARTHWORKS, PAVEMENTS AND BRIDGES. THE SECOND ARTICLE OUTLINES THE TECHNICAL STUDY: DESIGN OF THE EMBANKMENTS, EVOLUTION IN COHESION, FOLLOW-UP STUDY OF EARTHWORKS, LESSONS DERIVED FOR PROJECT DESIGNERS AND BUILDERS, GUIDELINES FOR THE ERECTION OF EMBANKMENTS, USE OF AN EXPERIMENTAL EMBANKMENT, LATERAL DISPLACEMENT OF THE SOIL AGAINST THE PILES. AN APPENDIX DESCRIBES A TEST FOR THE UTILIZATION OF PRECRUSHED SAND-SLAG AND OF A SURFACE DRESSING CONTAINING PRECOATED CHIPPINGS.
