Project Description
Conventional practice for the City of Orrville, Ohio, street construction and reconstruction projects has been the use of conventional Welded-Wire Fabric (WWF) as the temperature/ shrinkage reinforcement for their concrete pavements. In August of 2012, Orrville relied on engineering judgment to allow a macrosynthetic fiber reinforcement alternative to the 4×4-6×6 WWF reinforcement. FORTA-FERRO® certainly aided the ease of construction for the project by eliminating the placement labor of the wire mesh, while adding to the pavement toughness, impact resistance, and crack control. Based on steel-to-fiber calculations, project engineers specified 4 Ib/ cu yd of the 2-1/4“ long macro fiber as a reinforcing equivalent for this 2,700 foot long street pavement project. Conventional control-joint spacing was utilized within the 29 ft wide, 9 in thick pavement, covering almost 80,000 sq ft using almost 2,200 cubic yards of fiber reinforced
concrete.
Key Points:
- Added Durability and Toughness
- Reduced Cracking
- Impact Resistance
