Special problems Mu-meter Bonded rubber
Special problems Hydroplanning effect on Airports Pavements during heavy rain. Coefficient of friction very critical. Hveem California
Special problems Grooving System
New Mexican proposal for Coefficient of Friction AIRPORT PAVEMENT SURFACES Measurements on all the Runway length a) Once a year evaluation b) (1) in Center Line c) (4) at 3 and 6 m on each side d) Method ASTM E 670 e) Equipment Mu-Meter or similar • Key Notes: • Until now, the official value for C. F. is 0,5 min (wet and dry) • 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.
PROFILE INDEX ACCORDING TO THE NEW MEXICAN STANDARDS FOR HIGHWAYS
New Mexican proposal for Profile Index AIRPORT PAVEMENT Measurements on all the Runway length: a.- (1) in Center Line b.- (10) at 2, 4, 6, 8 and 10 meters on each side covering 20 m width c.- Once a year evaluation 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”
