Dynamic Characteristics of Warm Mix Foamed Asphalt Mixture in Seasonal Frozen Area

Advances in Materials Science and Engineering, Volume 2019, Issue 1, 2019., 2019
In order to study dynamic characteristics of warm mix foamed asphalt mixture in seasonal frozen area, cylinder dynamic modulus test of four kinds of mixture with two gradations and three kinds of asphalt was carried out by UTM‐100. Then, the effects of test temperature, loading frequency, and foaming water consumption on dynamic modulus were analyzed ...

Preparation, Structure, and Properties of Modified Asphalt with Waste Packaging Polypropylene and Organic Rectorite

Advances in Materials Science and Engineering, Volume 2019, Issue 1, 2019., 2019
The modified asphalt with waste packaging polypropylene (WPP) and WPP/organic rectorite (OREC) was prepared by the melt blending method. The effects of OREC on the physical and aging properties of WPP‐modified asphalt were studied. The morphologies, microstructure, and thermal properties of WPP‐modified asphalt and WPP/OREC‐modified asphalt were ...

Rut Performance of In Situ Warm Mix Asphalt Overlays with Evotherm 3G in North Dakota

Journal of Engineering, Volume 2019, Issue 1, 2019., 2019
As warm mix asphalt (WMA) pavements afford compaction at temperatures several dozen degrees lower than hot mix asphalt (HMA), the rate of cooling drops dramatically allowing paving to continue into colder weather. For this study, field samples from the Valley City project were collected after being in service (aged) for three years.

Moisture Susceptibility of Warm Mix Asphalt (WMA) with an Organic Wax Additive Based on X‐Ray Computed Tomography (CT) Technology

Advances in Civil Engineering, Volume 2019, Issue 1, 2019., 2019
The warm mix asphalt was fabricated with different moisture contents (0%, 1%, 2%, and 3%) of limestone aggregates using the Superpave gyratory compactor. The moisture susceptibility of asphalt mixtures with an organic wax additive RH was studied. The samples were compacted and tested using the modified Lottman test AASHTO T283, and the X‐ray computed ...

A Comparative Life Cycle Assessment (LCA) of Warm Mix Asphalt (WMA) and Hot Mix Asphalt (HMA) Pavement: A Case Study in China

Advances in Civil Engineering, Volume 2019, Issue 1, 2019., 2019
Generally, the warm mix asphalt (WMA) technology can reduce the mixing and paving temperature effectively as compared with that of hot mix asphalt (HMA), which is considered more environment‐friendly. In this study, the environmental impacts and resource consumptions of WMA and HMA pavements were analyzed comparatively using the life cycle assessment ...
