New Economical Structures Made of Thin Composite Whitetopping

Paper by POTTIER from ISCR 9th 2004 Instanbul Turkey

In 1996 a new pavement structure was launched in France under the name « Béton de Ciment Mince Collé (thin composite whitetopping) », BCMC. This technique was an adaptation of the Ultra Thin Whitetopping (UTW) developed in the USA since 1990. But while in the USA this technique was mainly used for reparation of rutted flexible pavements, in France new structures were perfected, taking into account the bonding between the concrete and the coated material of the subbase. This article deals with the first applications made according to this type of design, two on industrial sites and a third application on a roundabout near the town of Chambéry.
