A Laboratory Investigation into the Effects of Coarse Aggregate Angularity on Performance of WMA
Advances in Materials Science and Engineering, 2018 This study evaluated the effects of coarse aggregate angularity (CAA) on the performances of warm mix asphalt (WMA) because previous studies have predominantly focused on the effects of CAA on the hot mix asphalt (HMA) performances.

Advances in Civil Engineering, Volume 2023, Issue 1, 2023., 2023 Low‐energy asphalt (LEA) mixture, as an alternative to hot mix asphalt (HMA) due to its lower mixing temperature, has advantages such as reducing energy consumption and environmental pollutants. LEA has poor performance characteristics due to the presence of water in its manufacturing process and low mixing temperature.

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022 In order to investigate the feasibility of warm mix technology in high‐viscosity asphalt mixes, in the current experiment, Shell 70 Grade A asphalt (base asphalt) was modified by AR‐HVA (a high‐viscosity modifier), and the high‐viscosity modified asphalt was further incorporated with two surface‐active warm mixes (Evotherm M1 and Retherm). The physical

Advances in Materials Science and Engineering, Volume 2021, Issue 1, 2021., 2021 One of the failure mechanisms associated with asphalt paving layers, especially on steel deck bridges, is large permanent deformation, which adversely affects its long‐term performance in service. Thus, epoxy resin was introduced in asphalt paving industry to tackle permanent deformation of asphalt mixtures due to its thermosetting nature.

Study on Epoxy Resin‐Modified Asphalt Binders with Improved Low‐Temperature Performance
Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021 Epoxy resin‐modified asphalt binder (ERMAB) has been wildly used in the pavement of steel bridges, while the improvement on its low temperature is still a big challenge to researchers. This paper tries to improve the low‐temperature performance of ERMAB by optimizing the modifier, epoxy resin.

Laboratory assessment of performance of WMA containing Sasobit
IOP Conference Series: Materials Science and Engineering, 2021 AbstractOver the time, comparing with the traditional hot mix asphaltic (HMA) mixture, the warm mix asphaltic (WMA) mixture has become extremely widespread in the construction projects of highways because the WMA mixture provides the possibility of manufacturing asphalt mixes at a lower temperature than the traditionally utilized HMA.

Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021 Stone matrix asphalt (SMA) mixtures are one of the most resistant types of asphalt mixtures known to date that the bulk load is borne by the aggregate skeleton. In this research, the effect of crumb rubber powder (CRP), Vestenamer polymer, and warm additives, including Sasobit, ZycoTherm, and a porous and warm mix asphalt (PAWMA), was investigated on ...
