“…The WP method is being used by many researchers to study effects of antistripping agent, warm mix additives on SFE of asphalt binder and to determine compatibility ratio (CR) of different types of asphalt-aggregate combinations [3][4][5][6][7]11]. A good correlation between the CR estimated from the WP method and laboratory tests has been reported by Bhasin and Little [4].…”

“…(8)). Many of the recent studies reported SFE measurement of unaged asphalt samples [1,3,[5][6][7][9][10][11]15], considering that initial coating/bonding of asphalt binder over aggregates occurs at the initial stage of mix production, prior to start of aging of binder. Thus, SFE of unaged asphalt binders was measured in the present study.…”

“…The contact angles of binders should be measured using at least three probe liquids of known SFE components. In this study, three probe liquids namely: distilled water, glycerol and formamide were used [3,7,11,12,15] to measure contact angle of selected asphalt binders. Thereafter, the SFE components of asphalt binders were calculated using the acid-base theory (Eq.…”

The primary objective of this study is exploring the moisture susceptibility of unmodified and SBS-modified hot and warm mix asphalt mixtures. To this end, two different WMA additives including Aspha-min and Sasobit were employed to fabricate WMA specimens. The moisture susceptibility of warm polymer modified asphalt (WPMA) mixes was evaluated using modified Lottman test at 25°C according to AASHTO standard (T 283). In addition, the effect of different percentages of hydrated lime (from 0% to 2%) and Zycosoil (from 0% to 0.1%) as anti-stripping additives on the moisture susceptibility of the mixtures was explored. Based on the ITS test results, WPMA prepared with Sasobit additive and polymer modified asphalt (PMA) mixes satisfied the desirable tensile strength ratio (TSR) (above 80%) but Aspha-min WPMA mixes had TSR lower than 80%.

Abstract:The influence of organic additives (Sasobit and RH) and water on the adhesion of the asphalt-aggregate interface was studied according to the surface free energy theory. Two asphalt binders (SK-70 and SK-90), and two aggregate types (limestone and basalt) were used in this study. The sessile drop method was employed to test surface free energy components of asphalt, organic additives and aggregates. The adhesion models of the asphalt-aggregate interface in dry and wet conditions were established, and the adhesion work was calculated subsequently. The energy ratios were built to evaluate the effect of organic additives and water on the adhesiveness of the asphalt-aggregate interface. The results indicate that the addition of organic additives can enhance the adhesion of the asphalt-aggregate interface in dry conditions, because organic additives reduced the surface free energy of asphalt. However, the organic additives have hydrophobic characteristics and are sensitive to water. As a result, the adhesiveness of the asphalt-aggregate interface of the asphalt containing organic additives in wet conditions sharply decreased due to water damage to asphalt and organic additives. Furthermore, the compatibility of asphalt, aggregate with organic additive was noted and discussed.
