Regularities of tension distribution in the intraeconomic highways soil base

The localand intraeconomic highways located in borders of rural settlements are intended for year-round journey within agricultural territories. For such roads it is necessary to take into account the stamp test’sresults, such asstampdeflection, distribution of pressure upon soil as on the surface contacting and on basis depth atpavement design. Research objective is obtaining analytical dependence of tension change on depth in the soil basis under a rigid stamp. For a goal realization the analytical methods of soil bases tension determination with use of mathematical apparatus of the theory of elasticity and soil mechanics were analysed. The comparison of theoretical decisions with the available results of experimental studies is shown. The best coincidence to experiment was shown by the exponential dependence offered in the present reportwhere instead of one coefficient of attenuation on depth two constants are used: the lateral pressure coefficient and the experimentally establishedconstant for this type of soil. Use of the offered dependence will allow to describe more precisely a tension of soil baseof pavement and to apply to pavement design both intraeconomic appointment and general use.
