Abstract :

High construction costs when combined with awareness regarding environmental stewardship have encouraged the use of waste and renewable resources in asphalt modification. Increasing energy costs and the strong worldwide demand for petroleum has encouraged the development of alternative binders to modify or replace asphalt binders. The benefits of using alternative binders are that they can help save natural resources and reduce energy consumption while maintaining and, in some cases improving asphalt performance. Use of alternative (or byproduct) materials in asphalt mixtures may be one of the most complicated of the highway uses. The best use must be carefully engineered and designed, including the design of the mixture itself, the effects of the alternative materials on the asphalt binder behavior, and the pavement into which it will be incorporated. Common alternative has been observed that most, if not all, of these alternative binders contain chemical compositions somewhat similar to those of conventional asphalt binders (e.g. hydrocarbons, aromatics, saturates, and asphalt). However, tests indicate significant variability in the properties of alternative binders. In addition, the modification mechanism (chemical) for asphalt with alternative binders depends on the base asphalt and is therefore not well understood. It is critical to evaluate the technical feasibility of incorporating alternative binders into conventional asphalt binders for use in pavements. Because of the urgent need for infrastructure rehabilitation and maintenance, the introduction and application of such sustainable and environmentally friendly materials will have significant impact on the national economy as well as energy sustainability. It is necessary to determine what types of byproduct materials are suitable for use as alternative binders. Any alternative material under consideration must be adequate in chemical composition so that the asphalt material can be compatible using the highest amount of alternative binder possible. Considering the urgent need for infrastructure rehabilitation, the introduction and application of these sustainable and environmentally friendly materials could have significant impacts on the national economy as well as energy sustainability.
