Улучшение свойств конструкций лесных автомобильных дорог на основе использования шлаков металлургических производств

Abstract

In the given work the analysis of physicomechanical properties of slags of the Belarus metal works is resulted, tests by definition structure, optimum density and humidity of a mix of slag and peschano-gravijnoj mixes are conducted. Results of definition of characteristics of various mixes (optimum humidity, the maximum density, the elasticity module) have shown that replacement of 20-30 % of natural gravel with metallurgical slag is effective and expedient - bearing ability гравийных the bases from such mixes and the density increases a little. On the basis of the received results recommendations about the device gravil the bases with use of 20-30 % of metallurgical slag are made.
