    abstract = {The High Modulus Asphalt Concrete Mixture (HMACM) or (EME) (Enrobes a Module Eleve)
developed in France, since, 1980 by Labatories Central des Ponts et Chaussees (LCPC). Due to the increasing
in traffic intensity and axle loading this type of mixing were suitable for pavement subjected to heavy duty.
Experiments showed that EME mixtures have an excellent moisture damage resistance permanent deformation,
fatigue cracking and reducing costs of maintenance and a significant reduction in thickness of pavement.
Because of the high stiffness of EME mixes, the stresses transformed to the bottom laid layer by repeated traffic
wheel loads were reduced effectively. This study intend to focus the light into the possibility of producing
asphalt mixtures (EME1) and (EME2) that exhibit high degree of high stiffness in order to with stand against
the initiation of rutting. The evaluation process will be based on conducting the pneumatic repeated load
system and the wheel-tracking test. For this purpose, hard asphalt cement with a penetration grade of 20-30 for
EME comparing with conventional asphalt cement with penetration grade of 40-50. The results obtained
indicates that increasing the temperature from (25 to 4°C), Resilient Modulus (M ) reduced by 65 and 20% for r
conventional and (EME) for base course while at the binder course the resilient modulus reduced by 59 and
16% for conventional and (EME), respectively. Wheel track test results showed that permanent deformation
increased significantly with hard penetration grade bitumen, the rut depth was 2.55 mm while for
conventional bitumen was 16.15 mm for base course. While at binder course the rut depth was
2.43 mm while for conventional bitumen was 15.1 mm. This increasing in rutting resistance
important for reducing and preventing structural failure and in other hand for economy and reducing layer
thickness.}
