DEVICE FOR EVALUATING ADHESION PROPERTIES OF RIGID PAVEMENT ROADS

摘要

FIELD: road building; investigation of road accidents. SUBSTANCE: proposed device has tyre simulator installed on end of lever and coupled with main loading device, propulsion unit made in form of two-arm lever with axle of rotation in middle part installed for displacement in vertical guides and coupled with main loading device. Tyre simulator is mounted on one end of lever, and other end is hinge- coupled with additional loading device. EFFECT: improved accuracy of evaluation of road adhesion properties. 4 cl, 3 dwg
