Dynamic Modulus Prediction Validation for the AASHTOWare Pavement ME Design Implementation in Egypt
نویسندگان
چکیده
Dynamic Modulus, E* is a crucial property of the hot mix asphalt (HMA). For AASHTOWare Pavement ME design, an essential material input. can be measured in laboratory or predicted using different models based on some fundamental properties HMA. The NCHRP 1-37A and 1-40D prediction are two main adopted by to predict HMA mixture volumetrics, gradation, binder properties. objective this research was validate these local mixes for purpose regional application design Egypt. purpose, values ten locally plant-produced were laboratory. then used estimate same materials. Consequently, performance both studied comparing estimated values. results showed that model satisfactorily Egyptian with minimal bias high accuracy. yielded adjusted coefficient determination (R2) 0.86 480 measurements. On other hand, accuracy not satisfactory, very poor (Adjusted R2 = 0.18) bias. Afterwards, effect from pavement terms rutting, cracking, roughness further studied. Accordingly, twenty-four simulation runs typical cases conducted using, first, and, then, predictions had no significant distresses ranged 0.980, AC 0.9996 International Roughness Index (IRI). Hence, without compromising structural design.

Highways and in particular their pavements are the fundamental components of the road network. They require continuous maintenance since they deteriorate due to changing traffic and environmental conditions. Monitoring methods and efficient pavement management systems are needed for optimizing maintenance operations. Pavement performance prediction models are useful tools for determining the op...
