Application of Mechanistic Empirical Pavement Design Guide Software in Saudi Arabia

The present study explores the structural pavement design techniques related to distresses in terms of rutting, cracking and International Roughness Index (IRI) based on materials properties, roadbed characteristics, climate traffic loads for highway network Saudi Arabia (KSA). was focused selected site conditions at four regions KSA: Central (Riyadh); Eastern (Al-Ahsa); Western (Jeddah) Northern (Arar). Mechanistic-Empirical Pavement Design Guide (MEPDG) software used calibrate predict life according mentioned different KSA. This is first time where exact weather stations were run analysis determining realistic distresses. In study, structure low (700 AADTT) high (2000, 6000, 10,000 AADTT). tests MEPDG analyze predicted by an interval 5, 10, 15, 20 years. results show that preliminary example satisfies all target life, even provides a base designers can be modified as per project requirements using specific data traffic, material thickness, distress limit achieve life.
