FIELD: road building.
SUBSTANCE: invention can be used for evaluation of state of pavement. Proposed device contains staff with two supports on ends, mechanical reading device including measuring rod installed on staff in guide for vertical displacements and interacting with vertical displacements indicator, and staff horizontal position detector. Novelty is that stall is made in form of bar with upper and lower flanges and is furnished with measuring tape on upper flange which also carries staff horizontal position detector. Measuring rod is provided with sliding stop thrusting against lower support flange of staff for movement along staff. Supports are adjustable in height.
EFFECT: improved reliability of results of measurement, possibility of measuring gap in any point of pavement between supports.
