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.

Effects of moisture on warm mix asphalt containing Sasobit [PDF]
Scientia Iranica, 2017 The asphalt industry has been at the forefront of sustainable development. Warm Mix Asphalt (WMA) has been developed to cope with issues such as high energy prices and air pollution. These mixes require less energy and generate fewer pollutants during production in comparison with conventional Hot Mix Asphalt (HMA). Although a promising technology, the

Optical Characterization of Asphalt Binders Containing Wax Additives
Advances in Civil Engineering, Volume 2020, Issue 1, 2020., 2020 In between thermal‐oxidative (heat and oxygen) and photo‐oxidative (ultraviolet irradiation and oxygen) aging process of bitumen, photo‐oxidative aging mainly depends on the optical properties of the asphalt binder. The higher the reflection (or the lower the absorption of the binders), the better the pavement serviceability.
