Abstract (en)
[origin: WO2006106402A2] The invention relates to a device (10) for measuring the thickness (t) of a layer (14) of a substance or material deposited on a section of road (16) , which comprises sensor elements (S) which include a first and a second emitting device (El, E2) respectively capable of emitting an acoustic signal (18) and an optical signal (20) which are capable of being received by a respective first and second receiving device (Rl, R2) ; a computing unit (19) which is associated with said sensor elements (S) and is arranged to determine the thickness (t) as a function of the distance travelled respectively by the acoustic signal (18) emitted by the first emitting device (E1) , subsequently reflected by the layer (14) and received by the receiving device (Rl) ; and by the optical signal (20) emitted by the second emitting device (E2) , subsequently reflected by the section of 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) .
