Abstract: Publisher Summary This chapter examines the literature dealing with the chemical composition of asphalt and changes in composition during environmental aging that affect durability-related properties. The characterization of the chemical functional types gives a fundamental approach to the relationships between asphalt composition and asphalt properties, and the performance of asphalts and asphalt-aggregate mixtures. Differences in the quality of asphalts depend on their crude oil sources because different crude oils have different chemical compositions. A durable asphalt is defined as one that (a) possesses the physical properties necessary to produce the desired initial product performance properties, and (b) is resistant to changes in physical properties during long-term, in-service environmental aging. Durability is determined by the physical properties of the asphalt, which are determined directly by chemical composition.

TL;DR: In this article, the effect of ageing on bitumen chemistry and rheology was studied, where seven bitumens were aged according to the thin film oven test and the rolling thin-film oven test (RTFOT) and the binders were characterised using infrared spectroscopy, chromatography and dynamic mechanical analysis.

TL;DR: In this article, a hydrothermal process was used to convert swine manure to a bio-oil, which was fractionated to extract water, solid residue, and some of the organic compounds.
Abstract: This paper presents the production, modification, and characterization of biobinder from swine manure. A hydrothermal process was used to convert swine manure to a bio-oil. The bio-oil was fractionated to extract water, solid residue, and some of the organic compounds. The sticky residue after fractionation was used as a replacement for asphalt binder. This paper presents production and chemical and rheological characterization of the biobinder as compared with petroleum-asphalt binder. Biobinder from swine manure was found to be a promising candidate for partial replacement for petroleum-asphalt binder. Considering the limitations imposed on growth of swine farms by manure management practices and environmental regulations and the increasing demand for asphalt binder for infrastructure rehabilitation, this sustainable development will result in major improvements in environmental and economical impacts in both the agricultural and construction sectors. Hence, this study offers a unique approach that simu...

TL;DR: The findings of an extensive literature review on bitumen and asphalt mixture ageing test methods are presented in the paper as discussed by the authors, where the primary factors affecting the durability of bituminous paving mixtures, assuming they are constructed correctly, are age hardening and moisture damage.
Abstract: The findings of an extensive literature review on bitumen and asphalt mixture ageing test methods are presented in the paper. The primary factors affecting the durability of bituminous paving mixtures, assuming they are constructed correctly, are age hardening and moisture damage. Ageing of the bituminous binder is manifested as an increase in its stiffness (or viscosity). Water damage is generally manifested as a loss of cohesion in the mixture and/or loss of adhesion between the bitumen and aggregate interface (stripping). Short-term ageing is primarily due to volatilisation of the bitumen within the asphalt mixture during mixing and construction, while long-term ageing is due to oxidation and some steric hardening in the field. Of the tests used to simulate short-term ageing, the extended heating procedures of the thin film oven test (TFOT) and the rolling thin film oven test (RTFOT) are the most frequently used binder methods. In regard to long-term binder ageing, the oxidative pressure ageing vessel ...
