Abstract

Vorliegende Erfindung betrifft eine verfahrbare Vorrichtung zur Verdichtung eines Bodenschichtaufbaus (2), mit wenigstens einem Vibrationsmittel, wie einer Vibrationswalze (6) oder einer Vibrationsplatte (4), über das in wenigstens einem Lasteinleitungsbereich (8) den Bodenschichtaufbau (2) verdichtende Lastimpulse (P) einleitbar sind, wobei wenigstens ein erstes und ein zweites Detektionsmittel (10, 12) zur Detektion des E-Moduls des Bodenschichtaufbaus (2) vorgesehen sind, die derart von einander beabstandet an der Vorrichtung (1) angeordnet sind, dass das erste Detektionsmittel (10) eine Detektion im Lasteinleitungsbereich (8) und wenigstens das zweite Detektionsmittel (12) eine Detektion außerhalb des Lasteinleitungsbereichs erlaubt.The present invention relates to a movable device for compacting a bottom layer structure (2), comprising at least one vibrating means, such as a vibrating roller (6) or a vibrating plate (4), via the load pulses (P) compressing the bottom layer structure (2) in at least one load introduction region (8) ), wherein at least a first and a second detection means (10, 12) are provided for detecting the modulus of elasticity of the bottom layer structure (2) which are arranged at such a distance from one another on the device (1) that the first detection means (10) 10) allows detection in the load introduction area (8) and at least the second detection means (12) allows detection outside the load introduction area.

Darüber hinaus betrifft die Erfindung ein Verfahren zur Ermittlung eines Schicht-E-Moduls, wobei das erste Detektionsmittel (10) derart ausgebildet ist, dass es eine Detektion eines ersten Wertes W1 einer Einsenkungsmulde (14) des Bodenschichtaufbaus (2) im Lasteinleitungsbereich erlaubt, und das zweite Detektionsmittel (12) derart ausgebildet ist, dass es eine Detektion eines zweiten Wertes W2 der Einsenkungsmulde (14) außerhalb des Lasteinleitungsbereiches (8) erlaubt.
