Abstract

Pavement life is determined by structural performance and degradation of the properties controlling wet friction between tires and pavement. Expulsion of the water from the interface is controlled by aggregate size, binder and mix design. Friction develops where most of the water has been displaced and depends on aggregate microtexture. Traffic reduces this fine texture, but the polishing is not a simple, continuous process. During certain periods the process reverses. Dust and other contaminants further complicate the process. Laboratory machines and procedures are described, which attempt to duplicate the process. Results are presented and the utility of the procedures for pavement management systems is discussed.

Résumé

La durée de vie des revêtements est déterminée par la performance structurelle et la dégradation des propriétés controllant la frottement en présence d'eau entre les pneus et le revêtement. L'expulsion de l'eau au contact du pneu est controllée par les dimensions du granulat, le liant ainsi que par d'autres détails de la couche superficielle. Le frottement se developpe à l'endroit où l'eau a été déplacée et dépend de la micro-rugosité du granulat. La circulation dégrade cette rugosité fine, mais le polissage n'est pas un procédé simple et continu. Il se peut dans certains cas que le procédé soit inversé. La poussière et d'autres agents de contamination rendent le procédé encore plus complexe. Des machines ainsi que des méthodes expérimentales pour effectuer ce polissage sont décritent. Des résultats sont présentés et on évalue l'utilité du polissage artificiel pour les techniques d'entretien des revêtements.
