Abstract

The invention relates to a device (10) for measuring the thickness (t) of a layer (14) deposited on a section of road (16) , which comprises sensor elements (S) which include a first and a second emitting device (E1, E2) respectively capable of emitting an acoustic signal (18) and an optical signal (20) which are received by a respective first and second receiving device (R1, R2) ; a computing unit (19) associated with said sensor elements (S) for determining the thickness (t) as a function of the distance travelled respectively by the acoustic signal (18) reflected by the surface of the layer (14) and received by the receiving device (R1) ; and by the optical signal (20) reflected at the interface between the layer (14) and the road (16) , and received by the second receiving device (R2) . The invention furthermore relates to a method for measuring the above-stated thickness (t) , and to a monitoring system which comprises the measuring device (10) .
