REHABILITATION ALTERNATIVES FOR RUNWAY INTERSECTION PAVEMENT, W. P. HOBBY AIRPORT

LOCATION:  HOUSTON, TEXAS

CLIENT:  CITY OF HOUSTON

CONSTRUCTION COST: NOT KNOWN

This project consisted of evaluation of the pavement at the intersection of Runways 4-22 and 12R-30L at William P. Hobby Airport and design of rehabilitation strategies. The objective of the study was to compare construction times and costs of conventional paving methods/materials to accelerated paving methods/materials; with the primary goal of achieving pavement rehabilitation with minimized interference to aircraft operations. Two basic approaches were considered:  (1) close the intersection until it could be reconstructed on an accelerated schedule, and (2) reconstruct the pavement on a night shift only basis, using materials and methods that would allow it to be opened during the day for aircraft operations. Materials which were considered included Pyrament concrete (high-early strength), normal concrete, precast panels, polymer modified asphalt, and conventional asphalt.  Six different approaches ranging in costs from $90,000 to $2,900,000 were evaluated and presented to the City in an engineering report.  Final design and contract documents were prepared in another contract.
