Title (EN) UNIFORM ASPHALT PAVEMENT AND PRODUCTION METHOD THEREFORE
(FR) CHAUSSEE UNIFORME EN ASPHALTE ET PROCEDE DE FORMATION
Abstract: front page image
(EN)A uniform asphalt pavement of substantial area composed of aggregates of varying natural qualities produced by a systematic process of mix design, mix analysis, and plant control. The method uses a Riguez Index which is characteristic of the fine aggregate portion of the job mix formula, and a flexibility/stability function that is empirically derived from different combinations of crushed fine and blend sand. The Riguez Index is compared with volumetric representations of blended mixtures thereby to provide means for analyzing and controlling voidage variations in the mixture resulting from natural changes in aggregate quality. The Job Mix Formula is controlled by controlling the gradation over a single sieve size, controlling the quantity of asphalt cement, and/or controlling the quantity of mineral filler at the mixing plant.
(FR)Une chaussee uniforme de surface notable formee d"aggregats de qualites naturelles variables par un procede systematique de dessin de melange, d"analyse du melange et le controle de l"installation. Le procede utilise un Index de Riguez qui est caracteristique d"une partie de l"aggregat fin de la formule du melange de travail et une formule de flexibilite/stabilite qui est derivee empiriquement de differentes combinaisons de fines broyees et de sable de melange. L"index de Riguez est compare avec des representations volumetriques de melanges assembles afin de fournir des moyens pour l"analyse et le controle des variations de vides dans le melange resultant de changements naturels de la qualite de l"aggregat. La formule du melange de travail est verifiee en controlant la graduation sur une seule taille de tamis, en controlant la quantite de ciment d"asphalte, et/ou en controlant la quantite de remplissage mineral a l"installation de melange.
