This book was released on 2010 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Warm mix asphalt (WMA) refers to technologies which allow a significant reduction of mixing and compaction temperatures of asphalt mixes. From previous studies, it is observed that warm mix additives work in different ways, either in reducing the viscosity of the asphalt binder or allowing better workability of the asphalt mix at lower temperatures through volume expansion in the binder. If the technologies of WMA are incorporated into rubberized asphalt mixes, which are generally produced and compacted at higher temperature than conventional mixes, it is possible to reduce the mixing and compaction temperatures of rubberized mixes to those of conventional mixes. This paper presents a limited study that characterizes the engineering properties of crumb rubber modifier (CRM) mixtures containing warm mix additives. Six CRM mixtures (two of control mixtures and four of warm mixtures) were prepared using two aggregate sources and two additives: Aspha-min® and Sasobit®. Evaluation of all mixtures included the following testing procedures: tensile strength ratio, asphalt pavement analyzer, resilient modulus, and resilient modulus after long-term oven aging. The results from this study showed that in general, there was no significant difference between the control and warm CRM mixtures for the properties evaluated in this study, indicating that the use of WMA technologies into CRM mixes is expected to have no negative effect on the mixture's engineering properties.

Available in PDF, EPUB and Kindle. Book excerpt: Crumb rubber is widely used as an environment-friendly material in asphalt industry to improve pavement performance properties. Warm mixture asphalt (WMA) refers to the technologies which allow a substantial reduction of mixing and compaction temperatures of asphalt mixtures through decreasing the viscosity of asphalt binders. In general, the crumb rubber modified (CRM) asphalt mixes require higher temperatures compared to conventional hot mix asphalt (HMA). However, if the technologies of WMA are incorporated, it is predicted to reduce the mixing and compaction temperatures of rubberized asphalt mixtures. For utilization of rubberized mixes in WMA industry, it is needed to investigate the properties of CRM binders with warm additives depending on CRM contents, additive types, aging states, and other experiment variables. This research investigated CRM binders with wax warm additives, and the objectives included: 1) quantifying viscosity changes dependent upon mixing temperature and hauling period through Rotational viscometer test; 2) evaluating the effect of blending time on viscosity; 3) investigating the performance properties of recycled aged CRM binders containing wax additives through Superpave binder tests; 4) evaluating the microstructural properties using an environmental scanning electron microscope (ESEM) and an atomic force microscopy (AFM). The following conclusions were drawn based on the comprehensive laboratory investigation: 1) crumb rubber contents and wax types were found to have significant influence on the viscosity properties of CRM binders; 2) CRM binder with wax additive (LEADCAP) showed better rutting and cracking resistance compared to the control CRM binder for all aging states; 3) the wax additive in recycled CRM binder is observed to play an important role in binder properties even after subjecting to long-term aging processes; 4) the microstructures on morphology images seemed to have a good relation with the engineering properties of warm CRM binders.

Available in PDF, EPUB and Kindle. Book excerpt: With daily signals, Nature is communicating us that its unconscious wicked exploitation is no more sustainable. Our socio-economic system focuses on production increasing without considering the consequences. We are intoxicating ourselves on a daily bases just to allow the system to perpetuate itself. The time to switch into more natural solutions is come and the scientific community is ready to offer more natural product with comparable performance then the market products we are used to deal with. This book collects a broad set of scientific examples in which research groups from all over the world, aim to replace fossil fuel-based solutions with biomass derived materials. In here, some of the most innovative developments in the field of bio-materials are reported considering topics which goes from biomass valorization to the synthesis of high preforming bio-based materials.
