Concrete Applic ications • How did concrete help? – Nightly installation of new in-pavement lights • 43 lights and 5,300 LF of conduit trench in runway and taxiway pavement • Runway open to traffic the next morning • Specified 2000 psi compressive strength at 6:00 am – New full strength runway pavement for 3’ centerline shift of Runway 15R-33L • 400 LF of 24” thick new pavement section • Originally designed for construction during 54-hour closure, ultimately constructed in nightly segments • Phasing would not have been possible without the use of concrete. 2012 MdQI Conference Quality Transportation- A Hybrid Approach
