Abstract
Est divulgué un système permettant de mesurer et de contrôler lépaisseur des matériaux de couverture bitumés pendant la fabrication. Des faisceaux lumineux sont utilisés pour générer un signal de durée de trajet permettant de déterminer lépaisseur de la couche de matériau de couverture bitumé. Un contrôleur génère un signal de commande dépaisseur qui contrôle un enducteur et en modifie les paramètres pour quil produise une couche de couche de matériau de couverture bitumé de lépaisseur désirée.
