Abstract: The main objective of this study is to determine mix design parameters for cold in-place recycling with foamed asphalt. First, the foaming process of laboratory foaming equipment was validated by varying the water and ...

Abstract: The temperature of the existing asphalt pavement, which is to be recycled, would change from a low morning temperature of the spring/fall season to a high afternoon temperature of summer. However, most agencies do not ...

Abstract: Over the decades, significant efforts have been made in evaluating pavement condition by mounting cameras on a vehicle and automatically analyzing images by incorporating digital image processing techniques. Despite recent ...

Abstract: The main objective of this study is to validate a new mix design procedure for cold in-place recycling using foamed asphalt (CIR-foam) developed for the Iowa Department of Transportation. First, reclaimed asphalt pavement ...

Abstract: A cold in-place recycling (CIR) layer is typically overlaid by hot-mix asphalt (HMA) to protect it from water ingress and traffic load. Most public agencies have different curing requirements that specify the number of ...

Abstract: As part of the validation effort to evaluate the consistency of a new cold in-place recycling using foamed asphalt (CIR–foam) mix design process for the Iowa Department of Transportation, the dynamic modulus and repeated ...

Abstract: The objective of this research is to develop a microelectromechanical system (MEMS)-based intelligent hybrid Biaxial Strain Transducer (BiAST) sensor for predicting railroad fatigue life based on strain history. The developed ...

Abstract: In Central Vietnam, the aggregate typically originates from highly acidic rocks containing a significant amount of silicon dioxide (SiO2), leading to poor adhesion quality with virgin asphalt binder. Hence, the asphalt ...
