“…Nosetti, Pérez-Jiménez, Martínez, and Miró (2016) found that foamed asphalt mixture was significantly affected by water infiltration and resistance to water increased with increase in foamed bitumen content. Modarres and Ayar (2016) reported that foamed asphalt treated RAP materials including 1.5% Portland cement showed higher in-situ stiffness values than those of the limestone base layer. Dal Ben and Jenkins (2014) reported that FBM containing RAP materials resulted in a better value of resilient modulus when compared to control mixtures.…”

“…One of the widely used compaction methods is the Marshall Design approach (with suitable modifications to suit cold mixtures). Published literature indicates that FBM compacted with Marshall Approach results in optimum bitumen content, which is associated with the maximum density (Kim, Lee, & Heitzman, 2007;Modarres & Ayar, 2016). Recently, there has been a shift in design methods from Marshall Mixture design to performance tests like an indirect tensile test, resilient modulus test and moisture resistance test (Loizos & Papavasiliou, 2006).…”

Abstract. In recent years, the use of foamed bitumen technology along with Reclaimed Asphalt Pavement is gaining popularity across the world. The mechanical response of foamed bitumen mixtures containing reclaimed asphalt pavement is significantly influenced by constituent material properties and aggregate gradation. This article presents results from a study where foamed bitumen mixtures conforming to Indian specifications were evaluated. For this purpose, foamed bitumen mixtures using a different percentage of reclaimed asphalt pavement and bitumens were prepared. Initially, the foaming characteristics of virgin bitumens were evaluated to optimize for optimum water content and foaming temperature. In the second stage, mixture design was conducted to optimize for foamed bitumen content in foamed bitumen mixtures containing a different percentage of reclaimed asphalt pavement. Finally, these foamed bitumen mixtures were evaluated for their mechanical properties. The results from this laboratory study indicated properties of foamed bitumen and foamed mixtures are significantly influenced by properties of bitumen, the quantity of bitumen, and reclaimed asphalt pavement. Among the different mixtures, a mixture containing 50% reclaimed asphalt pavement exhibited best results in resilient modulus and resistance to moisture damage tests. A mixture containing 80% reclaimed asphalt pavement also shows acceptable strength and resistance to water susceptibility. Thus, it is possible to design high-quality bituminous mixes using higher reclaimed asphalt pavement percentages, which meet the required volumetric and desired performance criteria.

“…A comparison study between using coal ash and OPC in cold recycled asphalt mixtures was carried out by Modarres and Ayar [1]. The results revealed that the application of coal waste powder improved the mechanical properties of cold recycled asphalt material, but it could not achieve a positive impact on moisture damage resistance.…”

AbstractThe primary aim of this study is to investigate the enhancement of Cold Asphalt Emulsion Mixtures (CAEMs) using binary and ternary blended fillers (BBF and TBF), including an indepth assessment of the microstructure. Ordinary Portland cement (OPC), fly ash (FA) and ground granulated blast furnace slag (GGBS) were used for the BBF while silica fume (SF) was added to the BBF to obtain TBF. The mechanical and durability results indicated that the TBF was more suitable than the BBF for the production of CAEMs. The microstructural assessment indicated that the effect of BBF on the internal microstructure of CAEMs was slightly negative and more noticeable in CAEMs containing FA. It is proposed that the addition of SF to BBF mixtures can eliminate the delay in formation of hydration products caused by the bitumen emulsion. Overall, the research suggests that the use of BBF-CAEMs might be appropriate for pavements in cold climate whereas TBF-CAEMs would be effective in road pavements exposed to severe conditions both in hot and cold climates.

“…Al-Hdabi et al (2014) showed a significant improvement in cold rolled asphalt by incorporating a biomass fly ash with cement. A comparison study between coal ash and OPC in CBEM was carried out by (Modarres and Ayar 2016). The result revealed that the application of coal waste powder improved the mechanical properties of cold recycled asphalt material, but it could not achieve a positive impact on moisture damage resistance.…”

Abstract:Cold bitumen emulsion mixture (CBEM) is not yet widely used as a surface courses around the world. In this study, 0/14 mm size dense graded surface course CBEMs have been investigated. The mechanical performance was evaluated in term s of stiffness modulus over 3 months and resistance to permanent deformation under three different stress levels (100, 200, 300kPa) while durability evaluation was carried out in terms of resistance to moisture and frost damage. The study has also investigated the incorporation of low cement content (1%) with relatively sustainable by-product fillers, namely ground granulated blast-furnace slag (GGBS) and fly ash (FA) type 450-S on both mechanical and durability performance. A comparison has been carried out between the low and high cement content CBEM, as well as with respect to corresponding hot mix asphalt (HMA). The results revealed that the incorporation of GGBS and FA in CBEMs leads to superior performance, similar to CBEMs treated with high cement content and comparable to an equivalent HMA. Furthermore, GGBS replacement exhibited better performance than that of FA replacement. The findings suggest that the new sustainable types of CBEM can be developed for using as a surface layer for medium to heavy trafficked roads.
