Claims (1)

[Claims for Utility Model Registration] (1) A rod-shaped member whose lower end is inserted into the pavement, and a contact member whose lower surface abuts the surface of the pavement are provided at the lower end, and the rod-shaped member is coupled so as to be movable in the longitudinal direction. a movable member of a predetermined length, a detecting unit that converts the moving distance between the bar-shaped member or a member fixed to the bar-shaped member and the movable member into an electrical signal and detects the moving distance; a calculation unit that calculates the pavement thickness by calculating the electrical signal generated by the calculation unit; a display unit that displays the calculation result from the calculation unit; an operation unit that supplies an operation signal to the calculation unit; the detection unit and the calculation unit. 1. A pavement thickness measuring device comprising: a display section and a power supply section that supplies required power to an operation section. (2) The pavement thickness measuring device according to claim 1, further comprising a potentiometer as a detection unit that converts a moving distance between the rod-shaped member or a member fixed to the rod-shaped member and the movable member into an electric signal. . (3) The pavement thickness measuring device according to claim 1, further comprising a linear encoder as a detection unit that converts a moving distance between the rod-shaped member or a member fixed to the rod-shaped member and the movable member into an electric signal. (4) Claim 1, further comprising a storage medium for storing pavement thickness data output by the calculation unit as a calculation result.
