Narrative:

After a lightning strike the holes on runway 9R are repaired using quickrete hydraulic cement (aug/02). After a small airplane crashes on runway 9L (jan/03) quickrete is again used to patch digs and gouges. The repair process is to remove any loose material from the damaged runway surface, fill the existing void with cement and trowel the area smooth. The runway is constructed out of asphalt. Callback conversation with reporter revealed the following information: reporter states that improper runway repairs pose a hazard to flight. Because the runway surface is asphalt, a flexible substance, and the repair material, quickrete, is non-flexible. He stresses that repeated flexures of the surrounding material from aircraft operations will eventually allow the quickrete to separate from the surface and become FOD.

Title: RPTR STATES THAT CONCRETE HAS BEEN USED ON AN ASPHALT RWY AT MLB TO REPAIR LIGHTNING AND SMALL ACFT CRASH DAMAGE.

Narrative: AFTER A LIGHTNING STRIKE THE HOLES ON RWY 9R ARE REPAIRED USING QUICKRETE HYDRAULIC CEMENT (AUG/02). AFTER A SMALL AIRPLANE CRASHES ON RWY 9L (JAN/03) QUICKRETE IS AGAIN USED TO PATCH DIGS AND GOUGES. THE REPAIR PROCESS IS TO REMOVE ANY LOOSE MATERIAL FROM THE DAMAGED RWY SURFACE, FILL THE EXISTING VOID WITH CEMENT AND TROWEL THE AREA SMOOTH. THE RWY IS CONSTRUCTED OUT OF ASPHALT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES THAT IMPROPER RWY REPAIRS POSE A HAZARD TO FLT. BECAUSE THE RWY SURFACE IS ASPHALT, A FLEXIBLE SUBSTANCE, AND THE REPAIR MATERIAL, QUICKRETE, IS NON-FLEXIBLE. HE STRESSES THAT REPEATED FLEXURES OF THE SURROUNDING MATERIAL FROM ACFT OPS WILL EVENTUALLY ALLOW THE QUICKRETE TO SEPARATE FROM THE SURFACE AND BECOME FOD.
