Key Notes:1) Until now, the official value for C. F. is 0,5 min (wet and dry)2) The new proposal (2007) is in discussion and when approved (2008) will
require for all Airports minimum values of 0,66 and 0,72 for wet pavement critical condition.

New Mexican proposal for Profile IndexAIRPORT PAVEMENT

New Pavements (Runways)
max 10,0 2007
Existing Pavements max 15,0 2007
More than 15,0 Pavement must be treated
with corrective maintenance.
Key Notes:1) Until 1990, the official standard in Mexico had a maximum Value of P. I. = 30 inch/mile (47 cm/Km)2) From 1992, the standard value was improved requiring a maximum P. I. = 15 inch/mile (24 cm/Km)3) The new mexican proposal (2007) now in study and discussion, we expect to have it approved along 2008 and will require for all medium and large airports a maximum “Profile Index of 10,0 and 15,0 cm/Km”
