Characterization of Polymer Modified Asphalt Binders Containing Processed Oil
… investigates the impact of processed oil on asphalt binder PG 64-22 and conjugate of it with common modifiers such as Crumbed Rubber Modifier (CRM), Styrene-Isoprene-Styrene (SIS), Styrene-Butadiene-Styrene (SBS) and Petroleum Resin (PE). The binder was tested at different temperatures, and …

The effects of micro and nano size bauxite particles in modified asphalt binders and asphaltic mixtures
… to focus how to improve the characteristics of asphalt mix in order to reduce the pavement deteriorations. This study aims to evaluate the effects of Malaysian Micro bauxite powders (MBP) and Nano bauxite powders (NBP) with 3%, 5% and 7% by mass of bitumen. Conventional bitumen 80/100 …

Modeling of the linear viscoelastic response of polymer modified asphalt binders at intermediate and high temperatures
… the dynamic mechanical properties of polymer modified asphalt binders at intermediate and high service temperatures. A typical paving grade asphalt and seven different elastomeric modifiers were used. The modifiers, representing a wide variety of random copolymers and thermoplastic block …

An acoustic emission-based test to evaluate low temperature behavior of asphalt materials
Low temperature cracking in asphalt pavements located in cold climates is a major cause of pavement deterioration. Accurate evaluation of low temperature cracking behavior of asphalt materials is necessary in order to design pavements that are resistant to thermally induced cracking. Detrimental …

Prediction of Linear Viscoelastic Response of the Loss Shear Modulus of Polymer-Modified Binders
… mathematical models, developed on straight asphalt binders, are inadequate to characterize the frequency dependence of response of polymer-modified asphalt binders. In an earlier study at Virginia Tech, mathematical models were developed to predict the storage and loss shear moduli of …

INVESTIGATING THE INTERACTION BETWEEN THE RECYCLED COMPONENTS AND THE ASPHALT BINDERS, PLANT, LAB, AND FIELD MIXES
<p>"Modifying asphalt binders and mixes with recycled components is common practice due to their environmental and economic merits. Literature has indicated that different recycled components interact with (blend with) asphalt differently, ranging from no blending, partial blending, or full …

Evaluation of Warm Mix Additives for Use in Modified Asphalt Mixtures: Phase I
… use of warm mix additives with typical polymer-modified and terminal blend tire rubber asphalt mixtures from Nevada and California. The research effort is broken into three phases that are intended to evaluate the impacts of warm mix additives with typical polymer-modified and terminal blend …

Viscoelastic Modeling of Straight and Modified Binders at Intermediate and High Temperatures
… introduction of a new range of high performance asphalt binders. These new binders known as modified asphalt binders, have a more complex behavior than traditional binders. A review of the current mathematical models shows that most of them suffer from different drawbacks that make them …

Development of the Duomorph Asphalt Rheology Tester (DART): a self-contained, portable device for quality assurance testing of asphalt binders
… a bench prototype device, named as the Duomorph Asphalt Rheology Tester or DART, for use in quality assurance (QA) testing of asphalt binders. This self-contained, portable device was re-engineered from its original version developed in the 1970s to test the structural integrity of solid rocket …

Nano-scale evaluation of moisture damage in asphalt
Moisture damage is one of the major problems of asphalt pavements in United States. The moisture damage problem in asphalt has been studied for decades; still it remains an unsolved problem. Traditional macro-scale tests and methods failed to describe how and what factors affect moisture damage …
