FIELD: investigating or analyzing materials. ^ SUBSTANCE: method comprises measuring parameters of the pavement and calculating the grip coefficient. First, the ordinate of the micro-profile of pavement is measured, and then the dependence y = f(x), which describes the micro-profile in a given section, is determined. The dependence is used for determining the length of the curve of micro-profile, and parameters Ki of the pavement roughness are determined from the formulae proposed. ^ EFFECT: simplified method and reduced cost of determining. ^ 2 dwg
