“…A new cementitious binary blended filler (CBBF), comprising ground-granulated blast-furnace slag and a calcium carbide residue, has been developed and found to be very effective when generating an improved EBM (Dulaimi et al, 2020a). Findings indicate that there is a substantial improvement in ITSM, as can be seen in Figure 3.…”

“…The generation of ettringite needles, Portlandite and calcium silicate hydrate (C-S-H) gel, supports stiffness enhancement at both early and later stages. Previous investigations have revealed that the optimum blend (cementitious binary blended filler -CBBF) of GGBS and CCR is 4% and 2% by the total mass of aggregate, respectively (Dulaimi et al, 2020a).…”

“…Some researchers have suggested the use of additives to upgrade its properties, i.e. cement, fly ash, polymer, crushed glass and a variety of waste and by-products (Al Nageim et al, 2016;Kadhim et al, 2019;Wang et al, 2020a;Dulaimi et al, 2020a;Al-Kafaji et al, 2020). The benefits of such mixtures should theoretically, encourage their use as a structural layer material (James, 2006b;Du, 2018).…”

“…Many scholars have studied the strength formation mechanism of cement emulsified asphalt mixture. Anmar [ 26 , 27 , 28 ] studied the influence of emulsified asphalt and cement content on binary blended cement filler (BBCF), and the results showed that when the emulsified asphalt content was 8% and the cement content increased from 0 to 4%, the indirect tensile strength first increased and then decreased. When the cement content is constant at 3% and the emulsified asphalt content increases from 6% to 9%, the indirect tensile strength, compressive strength, and elastic modulus first increase and then decrease.…”

To meet the needs of the road industry for maintenance operations, a new cement emulsified bitumen mixture (CEBM) with early-strength, self-compacting, and room-temperature construction characteristics was designed. The strength formation mechanism of CEBM was revealed with a scanning electron microscope (SEM) and the surface free energy (SFE) theory. The mechanical properties and road performance of the CEBM were investigated extensively. The results show that before the demulsification of emulsified bitumen, the SFE of the bitumen–aggregate–water three-phase system was reduced due to the replacement of the bitumen–aggregate interface with water. The adhesion work between the emulsified bitumen and the aggregate is negative, which means the adhesion between the emulsified bitumen and the aggregate will not occur spontaneously due to the existence of water. The liquid emulsified bitumen improves the workability of the mixture and ensures that the mixture can be evenly mixed and self-compacted. After demulsification, the work of adhesion between the residual bitumen and the aggregate is positive, which means residual bitumen and aggregate can bond spontaneously. In addition, the hydration products of cement and aggregate form a skeleton, and the emulsified bitumen film wraps and bonds the cement and aggregate together, creating strength. The emulsified bitumen, cement content, and curing conditions have significant effects on the stability of CEBM. The recommended dosage of emulsified bitumen and cement is 8% and 8–10%, respectively. This material integrates the hardening effect of cement and the viscoelastic performance of bitumen and has good workability, mechanical properties, and road performance. Therefore, the CEBM is technically feasible for application to bitumen pavement.

“…Uma tendência atual consiste na pesquisa e desenvolvimento de misturas asfálticas que facilitem a trabalhabilidade, demandem menor consumo energético e que priorizem a minimização de impactos ambientais em seu processo de fabricação (Sena Neto et al, 2019). No ponto central do desenvolvimento de novos produtos relacionados às misturas asfálticas, encontra-se o uso de aditivos os quais promovem características aos ligantes que permitem modificar e aperfeiçoar algumas de suas características (Santos et al, 2015;Santana et al, 2018;Dulaimi et al, 2020;Xavier et al, 2020).…”
