Performance Evaluation of Dynamic Modulus Predictive Models for Asphalt Mixtures
Dynamic modulus characterizes the viscoelastic behavior of asphalt materials and is the most important input parameter for design and rehabilitation of flexible pavements using Mechanistic–Empirical Pavement Design Guide (MEPDG). Laboratory determination of dynamic modulus is very expensive and time consuming. To overcome this challenge, several predictive models were developed to determine dyn...
متن کاملAssessment of Resistance to Rutting of High Modulus Bituminous Mixtures Using Full-scale Accelerated Loading Tests
In anticipation of the introduction of high modulus materials in the Swiss standards, a research project has been carried out for the evaluation of these bituminous mixtures. These mixtures make possible to reduce rut in base courses. With a temperature of 50°C, three test sections (two with high modulus and one with a reference material for base layer), were built in a building for ALT and wer...
متن کاملAsphalt Additives to Control Rutting and Cracking
This report presents the results of an investigation of the performance of a variety of materials added to asphalt binders and mixtures to change their properties, particularly with respect to rutting and cracking. The approach included a field trial of seven polymer and particulate modifiers, supplemented by laboratory characterization of the materials used in the field. The modifiers evaluate...

15 صفحه اولThe Estimation of the Dynamic Modulus of Asphalt Mixtures Using Artificial Neural Networks
The dynamic modulus is the main input material property of asphalt mixtures for the modern mechanistic-empirical asphalt pavement design methods. The dynamic modulus is determined in laboratory by different procedures but in all cases, they require sophisticated equipment and well-trained personnel. When these experimental results are not available, they could be estimated using different predi...
