The paper presents a new simple mathematical model of a fundamental and applied elasticity theory problem, considering the stress-strain state of road-roller working members with elliptic surfaces and the road-building material interacting with them. The derived mathematical relations and the developed calculation theory prove the possibility of adjusting (optimizing) the parameters of contact interaction of flexible working members in roadrollers with elliptic surfaces, with the compacted layer by means of variating the design-constructive dimensions of semi-axles of the ellipseshaped surface of the roll under service conditions, thus adjusting force action on the compacted road-building material. The paper deals with an operation peculiarity of flexible working members with elliptic surfaces, offers a selection of materials and determines geometric parameters of flexible working members with elliptic surfaces. Based on the analysis of stress-strain state of the roll, two cases are considered suitable for constructive realization of the examined mathematical model.
