摘要

The utility model refers to devices for the rapid evaluation of the traction coefficient of a wheel with a hard surface of roads and aerodromes and can be used for scientific research in the field of development of asphalt-concrete mixtures and treads.;The device includes a pulling device connected through a dynamometer with a sledge trailer, to the runners of which are attached samples of treads.;A distinctive feature of the device is the use between the trailer and the pulling device of a two-wheel intermediate system that provides the application of a pulling force parallel to the surface of the pavement.;The device is designed to study the friction of wheel rubbers on asphalt concrete pavements and to obtain the dependence of friction and friction in dynamic mode on the type of rubber, tread pattern, load, sliding speed and ambient temperature.
