FIELD: road marking. SUBSTANCE: member 10 has convex hollow upper shell 12 made of plastic with side surfaces 12d, 12e, inclined end face surfaces 12b, 12c, upper surface 12f, peripheral lower surfaces and inner wall, lower base plate with modulus of elasticity 2070 MPa, large number of ribs passing between lower base plate and shell 12 directed perpendicular to inner wall of lower base plate, and light- reflecting lenses 50, 52 located on end face surfaces 12b, 12c. Modulus of elasticity of member exceeds 552 MPa, approximately. EFFECT: increased service life of marking member. 18 cl, 11 dwg
