Book Description
In their quest to improve overall pavement performance and durability, pavement engineers in recent years developed and used innovative asphalt mixtures utilising engineered or modified asphalt binders. The technology of asphalt modification using refining processes has evolved in the past decade as a viable, effective alternative. Results of an extensive evaluation of several paving asphalt binders modified by refining processes are presented and discussed. The evaluation used testing and characterisation systems developed in the Strategic Highway Research Program (SHRP) and recent revisions of these systems as proposed in the NCHRP 9-10 project. Rheological, failure and ageing properties at temperatures that simulate pavement service were measured and analysed. Handling, constructability and performance characteristics of asphalt binders modified by refining processes are evaluated and compared with those of conventional materials and asphalt modified by different types of polymers. Comparative performance results on asphalt mixtures are presented to show the effect of the improvements in binder characteristics on mixture performance. Results on new binder test methods developed as part of NCHRP 9-10 are also presented comparing binder and mixture performance characteristics. For the covering abstract of this conference see ITRD number E211271.

Book Description
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 either produced in the lab or collected from existing paving projects in Alaska. Various binder and mixture engineering properties were determined, including true high binder grades, complex modulus (G*), and phase angle ( ́) at high performance temperatures, multiple stress creep recovery rate and compliance, bending beam rheometer stiffness and m-value, Glover-Rowe parameter, T, rheological index, and crossover frequency for binders, and rut depth, critical strain energy release rate (Jc), Indirect tensile (IDT) creep stiffness and strength for mixtures. Binder cracking temperatures were determined using asphalt binder cracking device. Mixture cracking temperatures were determined with IDT creep compliance and strength data. It was found that rutting and cracking resistances of the mixtures with highly modified binders were better than the mixture with unmodified asphalt binder (PG 52-28). Future recommendations for highly modified asphalt binders applications and research were provided based on laboratory testing results and field survey evaluation.

Book Description
Asphalt modification is an important area in the development of new road and pavement materials. There is an urgent demand for road materials that can minimize fracture at low temperatures and increase resistance to deformation at high temperatures. The function of asphalt is to bind aggregate to protect it from water and other harmful agents. In the beginning asphalt was ideal for this purpose, but recently traffic loads have increased and environmental factors have deteriorated more rapidly than before. Asphalt is a byproduct of crude oil in the refining process, and it is considered a complex heterogeneous mixture of hydrocarbons. Asphalt modification has become an important research area, using several methods and new materials as modifiers.
