RISEffect of Weathering on Rubberized Porous European Mixture
Publisher: American Society of Civil Engineers
Abstract: This project investigated the effect of weathering (UV light, oxidative, and water) on the performance of rubberized porous European mix (PEM) by laboratory tests and field pavement investigation. Three rubberized PEM mixes ...
Fatigue Performance of Rubberized Stone Matrix Asphalt by a Simplified Viscoelastic Continuum Damage Model
Publisher: American Society of Civil Engineers
Abstract: The study investigated the fatigue performance of rubberized stone matrix asphalt (SMA) in the dry process and compared its fatigue characterization with SMAs with other typical binders. Five SMA mixtures were used with ...

Evaluation of Different VMA Estimation Methods for Asphalt Mixtures Containing RAP
Publisher: ASCE
Abstract: During asphalt mixture production, the bulk specific gravity (Gsb) of the mixture aggregate is not routinely measured to determine voids in the mineral aggregate (VMA), because this requires multiple tests and extended ...
Laboratory Evaluation of Effect of Addition Methods of Rejuvenators on Properties of Recycled Asphalt Mixtures
Publisher: ASCE
Abstract: The objective of this study was to compare the effectiveness of rejuvenators and determine how the methods of adding rejuvenators into recycled asphalt mixtures could affect their performance. In this study, five different ...
Nanoleveled Mechanism of Rejuvenated Aged Asphalt Binders by Different Rejuvenated Agents
Publisher: ASCE
Abstract: The purpose of this paper is to study the microleveled rejuvenating effects of different rejuvenating agents on aged asphalt binders. In this study, an original asphalt binder (Shuanglong) with a grade of Pen70 was aged ...
Impact of Additives on Low-Temperature Cracking Properties of Soft Binders Used in Cold Regions
Publisher: ASCE
Abstract: Low-temperature cracking is the main distress in asphalt pavement in cold regions (such as the arctic and subarctic regions) as the climate in these areas is severe in winter. While soft asphalt binders (such as PG 52-34 ...
Investigation of Thermally and Mechanically Balanced Structural Design of Insulated Pavements for Cold Region Applications
Publisher: ASCE
Abstract: Adding an insulation layer above the frost-susceptible layer in regular pavement structures was proved to be an efficient way to mitigate the influence of climates, such as frost heave and thaw weakening, on pavements in ...
