RESEARCH OF WEATHER CONDITIONS EFFECT ON THE COEFFICIENT OF COUPLING BETWEEN TIRE AND COVERINGS OF HIGHWAYS
Study focuses on the influence of the coefficient of tire adhesion of buses on the road surface by the amount of the full path braking in all weather conditions. The techniques survey ofthe adhesion of tires coefficient stopping distance e dependence with the road surface at different temperatures. To conduct their own research coefficient tire adhesion with the road surface used an apparatus POKS-5. Research has shown that the theoretical position of the linear dependence of the stopping distance of the coefficient of adhesion are confirmed; increasing the valueof adhesion coefficient is 1,5 times then the full braking path is reduced by about 1,9 times; the statistical characteristics of the model show a fairly high correlation between the factor of coupling properties of road cover and by braking the bus (correlation coefficient R = 0,89). Methodic recommendations were also given to security services trucking companies during seasonal safety instractions.
