Having proper joint spacing is vital to long-term performance of your concrete pavement. The rule-of-thumb for maximum joint spacing is 30 times the pavement thickness converts in unit of feet (i.e. Thickness = 4.0 inches; Joint Spacing = 120 inches or 10 feet). The maximum spacing for pavement thickness exceeding 6 inches is 15 feet. Keep panels as square as possible; the maximum length to width ratio is 1.25:1. The best practice for designers is to layout predetermined spacing on the plan prior to construction. To learn more, click here to setup an in-house workshop for you and your design staff.
