FIELD: testing road building materials. SUBSTANCE: rolls intended for placing samples and rolls are located in such a method that axes of them are parallel. Loading rolling is made of a material the stiffness of with is at least a degree of magnitude higher than that of the asphalt/concrete being tested. Unit to hold the rolling down to the sample is made in the form of two arm level with a weight installed on a frame. EFFECT: test conditions are close to real conditions. 1 cl, 2 dwg

Устройство для испытания асфальтобетона на сдвигоустойчивость относится к испытаниям дорожно-строительных материалов, в частности асфальтобетона. Задача, решаемая изобретением, - обеспечение возможности применения для испытания на сдвигоустойчивость асфальтобетона, а также приближение условий испытаний к условиям эксплуатации материала дорожных покрытий. Валы, предназначенные для размещения образца и ролика, установлены так, что оси их параллельны, нагружающий ролик выполнен из материала, жесткость которого по крайней мере на порядок выше жесткости испытуемого асфальтобетона, а узел прижима ролика к образцу выполнен в виде установленного на раме двуплечего рычага с грузом. 2 ил.A device for testing asphalt concrete for shear resistance relates to tests of road-building materials, in particular asphalt concrete. The problem solved by the invention is the provision of the possibility of using for testing the shear stability of asphalt concrete, as well as the approximation of the test conditions to the operating conditions of the material of the road surface. The shafts designed to accommodate the specimen and the roller are mounted so that their axes are parallel, the loading roller is made of material whose rigidity is at least an order of magnitude higher than the rigidity of the tested asphalt concrete, and the roller pressing unit against the sample is made in the form of a two-shouldered lever mounted on the frame with cargo. 2 ill.
