Laboratory Investigation of Using Calcium Lignosulfonate as an Oxidation Inhibitor in Bitumen

Advances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022
Asphalt mixtures are the major constituent of road constructions. Those mixtures expose to high‐temperature levels during the construction process and their life cycle. The bitumen aging occurred because of the harmful effects of elevated temperatures upon the asphalt mixtures, which leads to oxidation, evaporation, and physical hardening within the ...

Research on Rheological Properties by Desulfurized Rubber Powder/SBS Composite‐Modified Asphalt and Road Performance of Its Mixture

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
Desulfurized rubber powder and SBS were used as asphalt modifiers to study the rheological properties and performance of desulfurized rubber powder/SBS composite‐modified asphalt (DR/SBSCMA). First, the basic performance indicators such as penetration, ductility, softening point, and viscosity were studied.

Investigating the Effect of Calcium Lignosulfonate on the Durability and Performance of Asphalt Mixtures

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
Using bitumen modifiers to prolong the asphalt mixture’s life has been considered a practical approach in constructing asphalt mixtures. Among various bitumen modifiers, biomass ones have been more noteworthy because of their abundance, cost‐effectiveness, renewability, and sustainability. Calcium lignosulfonate (CLS), as a plant‐based bitumen modifier,

Durability Capacity Change of Rubber Powder Composite BRA Modified Asphalt Mixture

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
Both engineering practice and literature confirm that the high modulus asphalt mixture has superior performance. If modified, the final asphalt mixture can effectively improve the service life of asphalt pavement. Therefore, the design and test of this paper are trying to mix rubber powder and BRA to prepare high modulus Sup‐13 asphalt mixture. Through
