"AASHTO T 308-18 test method covers the determination of asphalt binder content of hot mix asphalt (HMA) by ignition at temperatures that reach the flashpoint of the binder in a furnace. The means of specimen heating may be the convection method or the direct infrared (IR) irradiation method. The aggregate remaining after burning can be used for sieve analysis using T 30." --

Asphalt is a complex but popular civil engineering material. Design engineers must understand these complexities in order to optimize its use. Whether or not it is used to pave a busy highway, waterproof a rooftop or smooth out an airport runway, Asphalt Materials Science and Technology acquaints engineers with the issues and technologies surrounding the proper selection and uses of asphalts. With this book in hand, researchers and engineering will find a valuable guide to the production, use and environmental aspect of asphalt. Covers the Nomenclature and Terminology for Asphalt including: Performance Graded (PG) Binders, Asphalt Cement (AC), Asphalt-Rubber (A-R) Binder, Asphalt Emulsion and Cutback Asphalt Includes Material Selection Considerations, Testing, and applications Biodegradation of Asphalt and environmental aspects of asphalt use

Accurate determination of asphalt content (AC) in hot mix asphalt (HMA) is essential to evaluate the performance characteristics of HMA pavements. The standard test methods for determining the AC, currently used by the Oklahoma Department of Transportation (ODOT) and other DOTs and asphalt industries, are time-consuming, environmentally unsuitable, and not applicable to several absorptive and dolomitic aggregates. This study has developed a systematic method for the determination of AC using volumetric properties of aggregate, asphalt, and HMA mix. The developed method employed the theoretical maximum specific gravity (Gmm) of an HMA mix, the bulk and apparent specific gravity of the aggregate (Gsb and Gsa), and the specific gravity of the asphalt binder (Gb). The CoreLokTM device is used to determine the volumetric properties of the aggregate and HMA mix. This developed method is easy to use, environmentally safe, time efficient, and accurate. Three different aggregates were selected for the study based on varying gradation, absorption, and ignition oven correction (IOC) factor. HMA mixes were prepared with each of these aggregates using 5.0 %, 5.5 %, and 6.0 % AC. For each of the mixes, AC was calculated using the proposed method and compared with the actual AC value. The predicted AC values were compared with AC values from the ignition oven method (AASHTO T 308) and the solvent extraction method (AASHTO T 164). Results showed that the proposed method predicted the AC of HMA mix accurately. The method introduces a correction factor (Cv), which needs to be determined during the design stage and specified on the mix design information. The Cv value is used to calculate AC by the proposed method during quality assurance and quality control at the production and service life of HMA.

The binder content of hot mix asphalt (HMA) is most commonly determined either by solvent extraction or ignition oven (IO) methods. Generally, the IO method has worked well with various HMA mixtures except those containing certain types of high mass loss (decomposing) aggregates, especially dolomite. For these aggregates, the high temperatures experienced during the ignition process initiate chemical changes within the aggregate particles, which result in variable mass losses. This, in turn, causes difficulties in calculating a consistent correction factor and determining a repeatable binder content. This paper presents a modified IO binder content determination method, which involves lowering the test temperature to 427°C and reducing the sample mass by half. In addition, only the bottom material basket of the typical IO test setup is used to avoid errors in the results due to temperature differentials that develop when, upon ignition, mixture from the lower basket starts heating the mixture in the upper basket. The proposed method was successfully verified by using six different plant-produced mixtures.
