REHABILITATION OF THE PAVEMENT OF FOUR ROUNDABOUTS BY MEANS OF THIN CONCRETE REINFORCEMENT ("THIN WHITETOPPING")
نویسندگان
چکیده
This article describes the design and construction of structural rehabilitation bituminous pavement four roundabouts by means arrangement a 12 cm layer vibrated concrete with fibres very close joints (technique known as "thin whitetopping"). The roundabouts, which belong to N-II National Road it passes through La Jonquera (Spain), are subject high levels heavy vehicle traffic (IMDp > 4,000 vehicles/day). In project phase, causes deterioration original road surface were studied, its remaining bearing capacity was characterised thickness be used calculated. most damaged areas, mixture completely replaced lower quality adhered reinforcement metal connectors. addition, detailed transitions between rehabilitated existing also carried out. Throughout document, different tasks out for adopted solution described in detail and, finally, recommendations provided based on results obtained. Keywords: Concrete, bonding, Concrete fibres, Reinforcement pavements concrete, Fuel resistance, Whitetopping.
