Evaluating suitability of energy efficient and anti-stripping additives for polymer and Polyphosphoric acid modified asphalt binder using surface free energy approach

Effect of Incorporating L-Shaped Folded Metal Aggregates on the Performance of Asphalt Mixtures

“…Surface free energy is the additional energy possessed by surface molecules of a substance due to unbalanced intermolecular forces. Its dispersion component originates from instantaneous dipole interactions between molecules, while the polar component arises from polar interactions such as permanent dipoles or hydrogen bonds [ 41 , 42 , 43 , 45 , 46 ]. The two components satisfy Equation (1): …”

Investigating the Interfacial Adhesion of Steel Slag and Long-Term Aged Asphalt Binder and Its Impact on Asphalt Mixture Performance

“…The work of adhesion (AD) quantifies the energy needed to separate the binder from the aggregate surface under dry conditions. It directly reflects the inherent bonding strength at the binder-aggregate interface, which plays a crucial role in determining the initial structural integrity of asphalt mixtures (Singh et al, 2018). The AD values for sandstone and steel slag aggregates, evaluated with VG30, CRMB, PMB, and their long-term aged variants, are presented in Fig.…”

Effects of Amine and Silane Based Anti-Stripping Agents on the Performance Characteristics of Styrene-Butadiene-Styrene Polymer Modified Asphalt Binder

“…Liquid anti-stripping agents (ASAs) are widely used to improve stripping resistance in bituminous mixtures. The popularity of these additives has increased because of their ease of application and greater stability compared to other conventional minerals, such as hydrated lime ( 1 – 4 ). Research highlights the effectiveness of using liquid ASAs to resist moisture damage in bituminous mixtures and underscores the importance of their essentiality with high-silica-content aggregates in rainfall-prone regions ( 5 , 6 ).…”
