Airborne Emissions Assessment of Hot Asphalt Mixing Methods and Limitations
Road Materials and Pavement Design, 2010Hot mix asphalt industries are required to meet airborne emissions thresholds, yet only a few types of emission measurements are available. This study is therefore aimed at evaluating the influence of operating parameters on airborne emissions at the plant stack, especially Gaseous Organic Compounds (GOC), in addition to identifying both the best ...

New Approach to Recycling Asphalt Shingles in Hot-Mix Asphalt
Journal of Materials in Civil Engineering, 2012AbstractThe objective of this study is to introduce a new approach to recycling asphalt shingles in asphalt paving construction in which recycled asphalt shingles (RAS) are ground to ultrafine particle sizes and blended with asphalt binder through a wet process.

Performance of Hot-Mix Asphalt Containing Recycled Asphalt Pavement
Transportation Research Record: Journal of the Transportation Research Board, 2011The purpose of this paper is to report the initial findings of an experimental program to design and assess the properties of recycled hot dense graded asphalt mixes. The mixes include Size 14-mm wearing course mix with and without recycled asphalt pavement (RAP). The RAP contents in the recycled mixes were 10%, 20%, and 30%. Laboratory designs of the

Oxidative Aging of Asphalt Binders in Hot-Mix Asphalt Mixtures
Transportation Research Record: Journal of the Transportation Research Board, 2011This study evaluated the effect of different aggregate sources along with their Corresponding change in mixture characteristics to determine the influence of both on binder oxidation rates and changes in mixture stiffness when compacted mixtures were exposed to laboratory aging conditions.

On the Mechanical Modeling of Asphalt Matrix and Hot Mix Asphalt Mixtures
Airfield and Highway Pavements, 2008This paper discusses the mechanical modeling of the asphalt matrix (AM) and hot mix asphalt (HMA) mixtures for two types of aggregates and one asphalt grade. The AM gradation was extracted from the HMA gradation passing No. 8-sieve. Hydrated lime was used as a binder additive to investigate the improvement in mixture properties.

Analysis of Temperature-Dropping Characteristics of Warm Mix Asphalt and Hot Mix Asphalt
Advanced Materials Research, 2012In order to research the temperature-dropping characteristics of warm mix and hot mix asphalt, some rutting test panels are used as specimens to determine the temperature-dropping characteristics of hot mix asphalt（HMA）, warm mix asphalt（WMA） with mixing additive “LuBo” and warm mix asphalt with mixing additive “Sasobit” under the conditions with ...

Cracking Performance of Lower Asphalt Binder Coarse Hot Mix Asphalt Mixes
2016Historically, asphalt mixtures in Minnesota have been produced to be fine-graded in nature. Recently, there are increasingly more coarse-graded mixtures being produced with relatively low asphalt binder content as compared to fine-graded mixtures. The performance of the coarser low asphalt content mixes is not known; therefore, the objective of this ...
