“…While polymer modified bitumen is the most popular in asphalt mix design, it shows more moisture damage resistance than the commonly used asphalt binder. In general, it is emphasized that the Modified Lottman test, Immersion Compression test and Boiling Water test are reliable tests in evaluating the moisture sensitivity of the asphalt mixture [30].…”

Stripping in asphalt mixtures is the one of foremost distress mechanisms. To prevent stripping, fatty acids (AS) and hydrated lime (HL) additives are often used as anti-stripping additives. The determination of the correct usage ratios of these additives and the storage stability of bitumen constitutes important research topics for anti-stripping additive applications. Three surfactants and hydrated lime were used in three ratios to evaluate the effect of additive ratio and type. Indirect tensile strength (ITS) values obtained from samples with one and three cycle modified Lottman conditioning and indirect tensile strength ratios (ITSRs) were interpreted in the context of water damage. The load-carrying capacity of the conditioned mixtures increased significantly. Even if the degree of damage was considerably increased at the end of three cycles, the integrity of the mixtures was maintained. Both AS and HL significantly increased water damage resistance. Modified Lottman conditioning has an observable level of damage. Additives remained functional and maintain their mechanisms of benefit, especially in the event of a high degree of damage.

“…The modified Lottman test (AASHTO T283) is the most widely used procedure for assessing moisture damage in asphalt mixtures. Other tests, such as the immersion-compression test (ASTM D1075/AASHTO T165) ( 7 , 8 ) and Tunnicliff–Root test (ASTM D4867) ( 9 , 10 ), were also developed. The immersion-compression test was withdrawn from the ASTM database in 2019 ( 11 ), while the Tunnicliff–Root test is similar to the widely used AASHTO T283 ( 3 , 12 ).…”

This study evaluated the effect of laboratory oxidation and testing temperature on asphalt mixtures’ moisture damage. The purpose of this study was to present a modified American Association of State Highway and Transportation Officials (AASHTO) T283 testing procedure that is more sensitive to moisture damage in asphalt mixtures. This study assessed the original test conditioning (OTC), short-term oxidative conditioning (STOC), and long-term oxidative conditioning (LTOC). Three performance grades (PGs)—PG 64-22, PG 76-22, and PG 52-34—and three test temperatures—the ambient laboratory temperature (25°C), asphalt intermediate temperature, and climate intermediate temperature (CIT)—were selected. To better understand the oxidation and moisture conditioning effects, AASHTO T283’s Tensile Strength Ratio ( TSR%) was utilized. Furthermore, additional analysis of the load–displacement curve parameters was carried out using the Indirect Tensile Asphalt Cracking Test, where an interaction diagram that included the mixture toughness ( Gf), ductile–brittle behavior ratio ( l75/ m75), and their interactions with CTindex was created. Statistical analysis was conducted using analysis of variance and Tukey’s post-hoc analysis to determine an appropriate oxidation and testing temperature where moisture damage is most sensitive. Results showed that higher oxidation and CIT had the greatest impact on TSR%. Moisture conditioning increased the CTindex and oxidation reduced the CTindex. The increase in CTindex was attributable to an increasing l75/| m75| and decreasing Gf. The CTindex decreased because of reducing l75/| m75| and increasing Gf. The statistical analyses showed that asphalt mixtures are more susceptible to moisture damage at STOC and LTOC than OTC. Overall, the findings highlight the need for an alternative oxidation conditioning and testing at the CIT to more accurately detect moisture damage in asphalt mixtures.

“…Due to the detrimental effect of moisture damage, it is important to test the susceptibility of an asphalt mixture to moisture damage. The tests for asphalt mixes are divided into tests for loose mixtures and tests for compacted mixtures [6,19,23,[49][50][51]. Despite the availability of tests for moisture susceptibility, none of them provides high correlation with field performance.…”

Adhesion in Bitumen/Aggregate System: Adhesion Mechanism and Test Methods

A literature review of the five main theories describing the interaction mechanisms in the bitumen/aggregate system was conducted: theory of weak boundary layers, mechanical theory, electrostatic theory, chemical bonding theory, and thermodynamic theory (adsorption theory). The adhesion assessment methods in the bitumen/aggregate system are described, which can be divided into three main groups: determination of adhesion forces for bitumen with different materials, determination of bitumen resistance to the exfoliating action of water with different materials, and determination of adhesion as a fundamental value (contact angle measurements, interfacial fracture energy, adsorption capacity and others). It is proposed to evaluate the quality of adhesive interaction in the bitumen/aggregate system in two stages. The authors recommend using the adhesion determination methods for these two stages from the second group of methods the determination of bitumen resistance to the exfoliating action of water with different materials. In the first stage, the adhesion in the bitumen/aggregate system is determined by an accelerated technique in which the used bitumen binder and mineral material are considered as test materials. After the first stage, there are positive results in the second tests on compacted mixtures (indirect tensile strength test, Modified Lottman indirect tension test, immersion-compression test, and Hamburg wheel tracking test).
