FIELD: construction of bridge roadways and overpasses near span-to-span joints, those between spans and abutments, and between approach embankments and passage slab. SUBSTANCE: structure has movement joint filled with macadam. Novelty is that macadam is enclosed by iron ring made of three-dimensional earth- reinforcing lattice with steel-fiber-concrete disturbing slab placed on its top. Extreme cells in iron ring may be filled with elastic mastic and fastened by means of anchors to embedded part of span or abutment slab. EFFECT: improved mechanical endurance and repairability of joint; facilitated passage over bridge roadway joints. 2 cl, 2 dwg
