METHOD FOR REPAIR OF CONCRETE OR REINFORCED CONCRETE PAVEMENTS OF ROADS, BRIDGES, AND AIRFIELDS

摘要

FIELD: construction engineering. SUBSTANCE: methods relates to construction and repair of concrete and reinforced concrete pavements. According to method, preliminarily produced fiber-concrete article with fibers protruding at one side of article to 5-30 mm is pressure-forced into preliminarily cleaned defective section of pavement which is filled with glue and fine-grained concrete mix containing separate fibers. Application of aforesaid method allows for cutting period of putting repaired pavement in operation together with enhancing strength and reliability of pavement. Service life of repaired pavement is also prolonged. EFFECT: higher efficiency. 2 cl, 2 dwg
