Title
(EN) SYSTEM FOR PREDICTING COMPACTION PERFORMANCE
(FR) SYSTEME DE PREDICTION DE PERFORMANCES DE COMPACTAGE
Abstract
(EN)
Compaction performance follows a well behaved response curve (10, 12, 14) for a particular material condition/compaction machine combination. Accordingly, a compaction response curve (10, 12, 14) is determined from measured values representative of material density after a first and second pass by a compaction machine. The response curve (10, 12, 14) is used to predict the number of passes required by the compaction machine to reach a desired density for the material, and thereby avoid making unneeded additional machine passes or passes which would not be effective due to diminished returns. The system may provide an indication when required compaction will not be achieved or will require an excessive number of passes, i.e. such as happens when moisture content of the material is high.
(FR)
Pour une combinaison condition du matériau / machine de compactage particulière, les performances de compactage suivent une courbe de réponse normale (10, 12, 14). Ainsi, on détermine une courbe de réponse de compactage (10, 12, 14) à partir de valeurs mesurées, représentatives de la densité du matériau après un premier et un second passage d'une machine de compactage. La courbe de réponse (10,12,14) sert à prédire le nombre de passages de la machine nécessaires pour arriver à une densité souhaitée du matériau, ce qui évite d'effectuer des passages supplémentaires inutiles ou inefficaces à cause de leur faible rendement. Le système peut également fournir une indication lorsque le compactage souhaité ne peut être obtenu, ou lorsqu'un trop grand nombre de passages est nécessaire pour l'obtenir, comme dans le cas de matériaux à forte teneur en eau.
