This paper is a case study of the cause of distress and evaltion of main Runway (29 L-ll R) of Mahrabad International Airport In 1320 , this run way was built (1800 length & 60 width ) from PCC
for small aircrafts. Later on 1329 and 13 39 the length of this Run way was inc reased to 3000 m and 4000m , respectedly
was increased to 3000m and 4000m,respectedly .Since 1320, this run wa y h a s bee nasphalt overlayed three times (for thickness of overdays see fig. l - a ) .
At the Present time this run way has a lot o f
distress including longitudinal transverse
and alligator cracks. On the
heavy traffic area intensity of distress
and setlement is such that this run way
is not safe for the Operation of Jet
aircrafts especen Jet fighters.
Based of field studies and the
results of several soil mechanics of
different layers of existing pavement
and the amount of airevaft Traffic,
some recommendution for Overlays has
been Presented . It has been sugested
that the first section of the run way
(Km 0+000 to 3+000) to be/5 asphalt
Overlayed and the remaining length
of run way which has less distress
to be 11 Overlayed.
