For the "Nationale 6" thickening between Auxerre and Cravant, the concrete pavement solution, in competition with traditional techniques, is particularly interesting on the economic point of view and held the Head District Equipment attention in agreement with the French Road Management. The strenghening technique consisted in implementing by 4 m...
Strengthening with concrete on the Nationale 6 in the Yonne County
A continuously reinforced concrete pavement (0.35 m thick) for the steel mill Sidmar in Belgium
The project consists of the construction of a continuously reinforced steel slag concrete pavement (0.35 m thick) on a base course of slag sand-bound granular material (0.85 m thick). The road (area 8,000 m2, width 10 and 17 m) has to lenable the transportation of hot (800 0 C) steel...
Slab behaviour of plain undoweled concrete pavements
The behaviour of plain concrete slabs, belonging to pavements with no dowels through transversal Jo~nts, is described. The slab behaviour is observed by means of field instrumentation, measuring absolute deflections produced by environment variations (temperature and moisture), by support rigidity variations and by a controled axle load. Deformations are measured...
Use of residues from the incineration of domestic wastes and other residual matters mixed with cement in road construction
The incineration of household refuse in the Federal Republic of Germany yields up to about 3.5 million tonnes of residual waste per year. About 90% of this consists of grate ash and about 10% of fly-ash, the latter mostly being collected in electrostatic precipitators. The grate ash consists chiefly of...
