FIELD: instrumentation.SUBSTANCE: in contrast to known methods to monitor irregularities of road carpet profile based on the measurement of the profile deviations by any method, the proposed invention implies that the road carpet quality is checked by the vibration characteristics of a moving vehicle, in particular, of a mobile vibration measuring system on a car base. The method implies that at the stage of putting a road into operation a reference base of road carpet evenness parameters is created while the characteristics of vibration effects of the road carpet irregularities with the measurement site correlation by a satellite positioning system are used as the above parameters; in the course of the road operation the road carpet state is monitored and the parameters of vibration effects caused by the road carpet irregularities are recorded, data of control measurements are compared to the reference data in the similar points of the route, basing on the difference of vibration effect parameters a decision on the road carpet repair or speed limitation at the problem road sections is made.EFFECT: possibility to reasonably recommend the road operation time until repair, speed limits for vehicles.2 dwg |
