| description | In the 1980s, the French Administration Roads LCPC developed high modulus mixtures (EME) by using hard binder. This type of mixture presented good resistance to moisture damage and improved . mechanical properties for asphalt mixtures including high modulus, good fatigue behaviour and excellent resistance to rutting. In Iraq, this type of mixture has not been used yet. The main objective of this research is to evaluate the performance of high modulus mixtures and comparing them with the conventional mixture, to achieve this objective, asphalt concrete mixes were prepared and then tested to evaluate their engineering properties which include moisture damage, resilient modulus, permanent deformation and fatigue characteristics. These properties have been evaluated using indirect tensile strength, uniaxial repeated loading and repeated flexural beam tests. EME mixes were found to have improved fatigue and permanent deformation characteristics, also showed more resistance to moisture damage than conventional mix by 9.3 percent and the resilient modulus
at temperature 60 oC increased by 63 percent. The general theme viewed from the results of this study has added to local knowledge the ability to produce more durable asphalt concrete mixtures with better serviceability using EME mixes. |
