There are many parameters that could affect the properties of asphalt mixtures, such as fiber additive, gradation type, nominal maximum aggregate size (NMAS), and asphalt. To evaluate influence these factors on crack resistance mixture, 10 different types mixtures were prepared. The indirect tensile cracking test (IDEAL-CT) semi-circle bending (SCB) adopted to anti-cracking ability samples. two...

The primary objective of this study is to develop a simplified Hot Mix Asphalt (HMA) dynamic modulus (|E*|) prediction model with fewer input variables compared to the existing regression based models without compromising prediction accuracy. ANN-based prediction models were developed using the latest comprehensive |E*| database that is available to the researchers containing 7,400 data points ...

The use of reclaimed asphalt pavement (RAP) is increasing importance due to fast-growing amounts demolished road materials. However, can contain relevant pollutants such as carcinogenic polycyclic aromatic hydrocarbons (PAHs) and toxic metals. In order improve the mechanical properties recycled asphalt, rejuvenators are used reduce stiffness aged binder. These in turn may potentially mobilise l...
