“…where σ IDT wet is the indirect tensile strength under the wet condition (kPa) and σ IDT dry is the indirect tensile strength under the dry condition (kPa). Besides, the retained Marshall stability test was determined to evaluate the effect of the filler on the loss of compressive strength of asphalt mixes after water immersion [29]. erefore, the MSR was computed as follows:…”

The spent fluid catalytic cracking (SFCC), waste from the petroleum industry, is nonstop increasing and causing environmental pollution in Vietnam. This study is an attempt to recycle SFCC in pavement construction. The study investigated the effect of SFCC, as a filler material in the hot-mix asphalt (HMA), on the essential characteristics of the asphalt concrete mix. First, the optimum percentages of bitumen and SFCC rate were investigated based on the Marshall design method. The HMA with SFCC showed more enhanced stability, flow, and other Marshall properties than the asphalt concrete mixture with the optimum limestone filler of 5%. Besides, the effects of SFCC rates on Marshall characteristics were explored. Second, performance tests were conducted to compare the mix with the different optimum content fillers of SFCC, limestone, and Portland cement. The tests include wheel tracking, indirect tensile, fatigue, and dynamic modulus tests to evaluate the performance of HMA with SFCC. It was found that the asphalt mixture with the optimum SFCC filler content can enhance pavement performance and improve the rutting and cracking resistance of the asphalt pavement.

Buton asphalt is a natural resource owned by Indonesia. One of the Buton asphalt processed is Retona Blend 55 Asphalt. Due to the abundant stock and better quality, Retona Blend 55 Asphalt can substitute Pertamina asphalt. Besides buton asphalt, Indonesia also owns coal mostly used for steam power plants. Coal fly ash has a size passing sieve number 200 and a hydrophobic profile. Thus, the authors utilized coal fly ash as the filler in the concrete asphalt mixture and Retona Blend 55 as the binder. The experiment employed the Marshall method to determine the effect of using coal fly ash as the substitute material of several fillers. The test results obtained 6% KAO with the filler application of 3%, 3.5%, 4%, and 4.5%, decreasing VMA, VIM, Marshall Quotient, and Stability. Moreover, the VFA, flow, and density values increased compared to testing without coal fly ash.

“…This results in strong binding of the aggregate and asphalt, thereby improving the water stability of the mixture. Ahmad et al [17] studied the effects of using two types of mineral fillers on the strength of asphalt mixtures in terms of the Marshall stability and retained strength, and showed that ordinary Portland cement (OPC) and pulverized limestone have a similar effect on the Marshall stability. Thus, the use of OPC resulted in higher values of retained strength.…”

Cement-containing mineral powder can effectively improve the moisture stability of an asphalt mixture; therefore, this study systematically summarizes the research status of cement–mineral fillers on the performance of an asphalt mixture and determines the limitations of related studies. In this study, long-term performance tests of styrene-butadiene-styrene- (SBS)-modified asphalt mixtures are designed and evaluated with different blending ratios of the cement–mineral powder under three aging conditions. Moreover, the effect of the cement–mineral composite filler on long-term performance of the asphalt mixture using different blending ratios is determined. Cement improves the high-temperature performance and water stability of asphalt mixtures, but only for certain aging conditions. Considering the regulations for the road performance of asphalt mixtures for three aging conditions, as well as long-term performance considerations, the results indicated that the mass ratio of Portland cement to mineral powder must not exceed 2:2. Low-temperature bending and splitting tensile tests confirmed that an excessive amount of cement filler will embrittle the modified asphalt mixture during long-term aging, thereby deteriorating the tensile properties. The mechanism by which the filler influences the performance of the asphalt mixture should be further studied from the perspective of microscopic and molecular dynamics.
