“…The disadvantages of cold mix asphalt are also obvious. Because water needs to evaporate from bitumen emulsion in order for the bitumen to develop adhesion with the aggregates, cold mix asphalt may need several weeks to reach its full strength [9]. This can result in inferior early strength and high porosity when compared with conventional hot mix asphalt [10][11][12].…”

“…In order to improve the early performance of cold mix asphalt, Ordinary Portland Cement (OPC) can be added to the mixture: 1-2% OPC (by mass) significantly improve the early mechanical properties [17,18] and the fully-cured material may acquire mechanical properties comparable or even better than those of an equivalent HMA [10,19,20]. Research on these composite materials, also called CAEC (Cement-Asphalt Emulsion Composite) [21,22], CBEM (cold bituminous emulsion mixture) [9,12], C-ETM (Cement-Emulsion Treated Mixture) [23] or CBTM (cement-bitumen treated material) [24], started in the 1970s. In all these materials, the primary binder is bitumen while cement is used as an admixture.…”

Cold mix asphalt, a promising substitute for conventional hot mix asphalt, is manufactured at ambient temperature using bitumen emulsion as binder. To improve its strength and durability, cement is often added to the mixture. This review (1) presents an overview about advances in cold mix asphalt modified with cementitious materials, often called CBEA (cement bitumen emulsion asphalt), (2) illustrates advantages and disadvantages of CBEA and (3) gives recommendations to produce homogenous CBEA mixtures

“…All indirect tensile stiffness modulus test values are the average of 3 specimens to ensure reliability. It should be noted that Poisson's ratio of 0.35 has been adopted as recommended by(Al Nageim et al 2012;Nassar et al 2016;Dulaimi et al 2016) for such types of mixtures. All CACB mixture samples were subjected to ITSM testing at ages 3, 7, 14 and 28 days.…”

“…This mixture does not require heating before mixing, which makes it more ecological and economical than other sorts of asphalt mixtures, such as conventional hot-mix asphalt (HMA) [4]. However, because of their higher air-void content after compaction and weak early-life strength, the BSM-E were traditionally considered inferior to HMA [1], and their use was almost restricted to surface treatments and reinstatement work on low-traffic roads and walkways [2][3][4][5]. With the latest developments in cold asphalt technology, this trend is changing currently, and the BSM-E are again gaining popularity within the scope of the fight against climate change in civil engineering [6][7][8].…”
