“…It may save a significant amount of fuel consumption, making it cheaper and environmentally friendly [5]. As per Jain and Singh, 2022 [6], the cost and CO 2 emissions of CBEM were 19% and 45.89% lower than HMA, respectively. However, their applicability is somewhat limited due to their lower early strength.…”

“…Ling and Bahia 2018 [31] introduced some new volumetric parameters, i.e., absorbed water volume by aggregates (VWA) and voids filled with water (VFW), based on different phases for CBEM with other parameters of HMA, i.e., air void (VA), total binder volume (VB), absorbed binder volume (VBA), effective binder volume (VBE), voids in mineral aggregates (VMA) and voids filled with bitumen (VFB). The volumetric parameters of CBEM are expressed from equation (3)(4)(5)(6)(7)(8)(9)(10)(11)(12), corresponding to both phases.…”

“…It can be observed that VMA decreased during the curing period. The VMA of CBEM is calculated by adding the air void, VBE, and the void filled with water (VFW), as per equation (6). As mentioned in figure 6(a), the air void decreases with the curing period.…”

“…As per MoRT&H 2013 [28], the air voids in CBEM should be 3%-5%, but practically, this is not achievable. Most of the studies achieved air voids greater than 8% [4,6,17,29,30]. The presence of water in CBEM over a period is likely to affect its volumetric and mechanical properties.…”

Cold bitumen emulsion mix (CBEM) is an emerging sustainable material for constructing the base or surface layer of flexible pavements, reducing energy consumption and global warming effects compared to hot mix asphalt. The main challenges associated with CBEM are low initial strength, moisture susceptibility, etc. This is primarily due to water encapsulation. The curing process allows the water to evaporate gradually over time, improving mechanical properties. This study investigates CBEM’s volumetric and mechanical properties under different curing conditions. CBEMs were prepared using low (50 blows) and high (75 blows) compaction efforts and cured at 25, 40, and 55 °C for 1 to 28 days. In volumetric characteristics, the air voids and voids in mineral aggregates decreased slightly with curing, while total binder volume decreased. Effective binder volume and voids filled with binder increased slightly, then decreased. The mechanical properties, i.e., Marshal Stability, Marshal Quotient, Indirect Tensile Strength (ITS), and Moisture Susceptibility parameters like the Indirect Tensile Strength Ratio (ITSR) and Retained Marshal Stability (RMS), were found to improve over time at each curing temperature. Using a high curing temperature further improved the mechanical characteristics of CBEM. The curing process was decelerated in case of CBEM prepared by high compactive efforts compared to CBEM prepared by low compactive efforts. The Michaelis-Menten model can be used to analyze moisture loss growth and the development of mechanical properties over time. The strength-maturity model can be developed by using ITS as strength parameters. There was a strong correlation between all mechanical characteristics and moisture loss.

“…It does not require heating since it has a lower production temperature, making it both economical and environmentally friendly (Al-Busaltan et al 2012). A study conducted by (Jain and Singh 2022) showed that the CBEM manufacturing can reduce costs and CO 2 emissions by around 20% and 46%, respectively, compared to HMA. Despite these significant benefits, CBEM has several disadvantages, such as lower early strength, higher air voids, poor moisture susceptibility, etc (Needham 1996, Read and Whiteoak 2003, Thanaya 2007a, which can further facilitates the rutting deformation, also.…”

Rutting is a worldwide recognized distress in bituminous pavement caused by repetitive passage of traffic loads at high temperature. High air voids and poor early strength of cold bitumen emulsion mix (CBEM) can cause rutting deformation even at lower temperatures, making it undesirable to practitioners. The CBEM can be effectively modified by using hydraulic materials as filler. The present study examines the effect of ground granulated blast furnace slag (GGBFS) and lime as fillers on rutting characteristics of CBEM at varying temperatures (i.e., 40, 50, 60oC). The conventional stone dust (SD) filler was partially replaced by GGBFS. For further modification, lime was added in CBEM containing GGBFS. Initially mix were selected for rutting test based on the results obtained by Marshall stability, indirect tensile strength, retained Marshall stability, and tensile strength ratio tests. Based on these results, 80% of GGBFS was optimized for CBEM production. Incorporating 20% lime with 80% GGBFS in CBEM further improved the properties mentioned above. Both mixes were selected for the rutting test, along with CBEM containing 100% SD and CBEM containing 20% lime, which were also selected for comparison purposes. Wheel tracking device was used for rutting test on CBEM at varying temperatures. Based on results, it was found that increasing testing temperature increases the rutting deformation. However, the CBEM containing GGBFS and lime by 80% and 20% of total weight of filler in the mix, respectively, gave better rutting resistance at each testing temperature and provide less temperature sensitivity. So, this paper introduces the blended GGBFS and lime as a new composition in CBEM that provides improved laboratory strength, moisture susceptibility resistance, and rutting resistance.
