Laboratory and Field Evaluation of Modified Asphalt Binders and Mixes for Alaskan Pavements [PDF]
In order to properly characterize modified asphalt binders and mixes for Alaskan pavements, this study evaluated properties of 13 asphalt binders typically used in Alaska from three different suppliers, and 10 hot mix asphalt (HMA) mixtures which were ...

Application of Cantabrian and Binder Drainage Tests in Designing of Porous Asphalt Binder Content [PDF]
Traditional mix design methods which normally incorporate the Marshall test are not appropriate to design porous asphalt because of the insensitivity of the Marshall stability values to variations in binder content.

Fundamentals of Asphalt Binders [PDF]
This presentation will help local agency personnel, consultants, and contractors to develop a continued under- standing of the asphalt binders used in hot mix asphalt. This presentation will cover fundamental aspects of asphalt binders, including how they are produced, how they are tested, and why and how their properties influence constructability and

Reversible Aging in Asphalt Binders [PDF]
X-ray diffraction, optical microscopy, and mass spectrometry techniques were used in an attempt to clarify the morphological and chemical features that are responsible for reversible aging processes that occur in asphalt binders during conditioning at low temperatures. The reversible aging term is used in this paper to capture all reversible processes (

New Mixture Additives for Sustainable Bituminous Pavements [PDF]
In an effort to improve mechanical properties of asphalt concrete, an exploratory research using mixture additives was attempted. Two different types of additives on two material scales were used: asphalt concrete (AC) level and binder level.

Aging of Rejuvenated Asphalt Binders [PDF]
An important concern that limits the RAP content in asphalt mixtures is the fact that the aged binder that is present in the RAP can cause premature cracking. Rejuvenators are frequently added to high RAP mixtures to enhance the properties of the binder. There is no existing method to predict the longevity of a rejuvenated asphalt.

Laboratory and statistical evaluation of the microstructural characteristics of Sand Asphalt Mortar
One of the problems encountered in asphalt pavements is fatigue damage, which is related to the type of aggregate, the rheology of the asphalt binder and its chemical composition, resulting in the emergence of microcracks and, subsequently, macrocracks.

Performance Damage Characteristics of Asphalt Binder Suffered from the Action of Sulfate
Sulfate erosion is a threat to durability and sustainability of pavement structure. In this work, the performance degradation of asphalt binder under internal sulfate erosion was investigated. Different dosages of Na2SO4 (0 wt.%, 2.5 wt.%, 5 wt.%, and 10
