METHOD FOR ASSESSMENT OF IRREGULARITIES Russian patent published in 1997 - IPC

Abstract RU 2082091 C1

FIELD: construction engineering. SUBSTANCE: method is used in construction of motor roads and airfields and also in assessment of their operational condition. Used as characteristic of irregularities is average mean-root-square deviation of profile points obtained for example in result of instrumental levelling with optimal discreteness and accuracy from lengths of straight lines drawn according to minimal squares method at their approximation of profile. Average mean-root-square deviation is connected with value of distance li between points of profile by following analytical expression: σ(li)av= σoμolνi

, , where σoμoν - parameters of irregularities. EFFECT: higher efficiency. 1 cl
