RISRheological Characteristics of Polyphosphoric Acid–Modified Asphalt Mastic
Publisher: American Society of Civil Engineers
Abstract: In this study, a dynamic shear rheometer (DSR) and bending beam rheometer (BBR) were employed to characterize the rheological properties of asphalt modified with polyphosphoric acid (PPA) and containing different mineral ...
Evaluation of Cracking Resistance in Alaskan Asphalt Pavement with Paving Interlayers
Publisher: American Society of Civil Engineers
Abstract: Paving interlayers have been used in asphalt concrete (AC) overlays in a variety of design and construction situations for more than three decades. In cold regions such as Alaska and other northern states, AC pavements are ...
Using Artificial Neural Networks to Predict the Dynamic Modulus of Asphalt Mixtures Containing Recycled Asphalt Shingles
Publisher: American Society of Civil Engineers
Abstract: The difference between hot-mix asphalt (HMA) containing recycled asphalt shingles (RAS) and virgin HMA in terms of composition and properties causes difficulties when engineers try to predict the performance of HMA containing ...
Rheological and Micro Properties of High-Viscosity Binder–Incorporated Polyphosphoric Acid and Rock Asphalt
Publisher: American Society of Civil Engineers
Abstract: AbstractTo enhance the performance of high-viscosity modified asphalt (HVMA), polyphosphoric
acid (PPA) and North American rock asphalt (NA–RA) were incorporated into styrene-butadiene-styrene
(SBS)/crumb rubber (CR) ...
