Concrete pavers are the fastest growing concrete product industry in North America.
CARRIES ALL TYPES OF LOADS Capable of bearing light foot traffic or heavy industrial loads, pavers are used for both sidewalks and airport taxiways. Because pavers re-create an old town look of cobblestone or brick paving, city planners of more than 30 major U.S. cities have used them to revitalize downtown shopping districts. They're used in pedestrian malls, sidewalks, crosswalks, and even city streets. Though block pavements are flexible, they have been shown to support loads up to 120,000 pounds. Thus they can be used in heavy-duty applications. In the United States, to meet ASTM C 936, Specification for Solid Interlocking Concrete Paving Units, they must have a minimum average compressive strength of 8000 psi, a maximum absorption of 5%, and a resistance of 50 freeze thaw cycles.
FLEXIBLE BUT STRONG Concrete pavers usually are laid on a bed of sand that is screeded over an engineered gravel base. Afterward, the joints are filled with sand, locking the pavers together. The load transfer provided by sand friction enables unmortared flexible pavements to carry higher loads than many rigid systems.
PRODUCTIVITY A typical five-person crew can install an average of 1,200 square feet of pavers in an 8-hour day. Machines that lay pavers can increase productivity by two to five times the rate of manual methods.
