Abstract
The paper examines the relationship between the sand (0.075–4.75 mm) and fines (<0.075 mm) on the achieved in situ compaction of natural and crushed materials used in the construction of the Egnatia Motorway in northern Greece. The study showed a clear distinction between the unprocessed samples and those produced by mechanical crushing. For the crushed materials, the results show an increase of in situ compaction with increased sand content and respective decrease of in situ compaction with increased fines content. The results can be used to aid the production of soil or aggregate mixtures which will meet specification requirements.
Résumé
L’article examine les relations entre le sable (de 0,075 à 4,75 mm) et les fines (<0,075 mm) sur la compaction en place de matériaux naturels et broyés utilisés pour la construction de l’autoroute Egnatia dans le nord de la Grèce. L’étude a montré une claire distinction entre les échantillons non traités et ceux produits par un broyage mécanique. Pour les matériaux broyés, les résultats montrent une augmentation de la compaction en place avec la teneur en sable et respectivement une diminution de la compaction en place avec la teneur en fines. Les résultats peuvent être utilisés pour aider à la fabrication de mélanges de sols et d’agrégats qui doivent satisfaire des spécifications particulières.
