REHABILITATION OF RUNWAYS 4-22 AND 17-35 W. P. HOBBY AIRPORT, CITY OF HOUSTON PROJECT NO. 316

LOCATION:  HOUSTON, TEXAS

CLIENT:  CITY OF HOUSTON 

CONSTRUCTION COST: $15,000,000

 

This project consisted of evaluating the existing pavements on Runways 4-22 and 17-35 using non-destructive deflection testing and pavement condition surveys. Alternative rehabilitation strategies were designed using FAA and elastic layer theory design methods. Life cycle cost analyses were completed in order to evaluate and compare the alternatives.  Pavement alternatives included complete reconstruction, overlays, keel replacement, and partial overlay/partial reconstruction. The recommended approach for Runway 4-22 was a 15" continuous reinforced concrete pavement (CRCP) with a cement stabilized base, and a 2" asphalt bond-breaker.  The recommended approach for runway 17-35 was a 3" partial depth milling of the existing asphalt surface, placement of a stress absorbing membrane innerlayer (SAMI) and construction of a 2.5" polymer modified asphalt (Novophalt) surface. Saw cut grooving was included for both runways.  These pavements were successfully constructed and are currently providing excellent performance for aircraft operations.
