• Cold bitumen emulsion mixtures
• Fly ash
• Stiffness modulus
• Creep stiffness

This paper reports the experimental test results of a research project aimed at developing a new cold bituminous emulsion mixtures (CBEM%26apos;s) containing fly ash from incinerated domestic and industrial by-products compared with those results of traditional control cold containing OPC and hot mix asphalt. %26lt;br%26gt;The main objectives of the experiments were to investigate the improvement in mechanical properties of CBEM%26apos;s due to incorporating OPC, and detect the possibility of replacing the OPC with waste fly ash materials. The mixtures mechanical properties investigated were: ITSM, creep stiffness. Durability in term of water sensitivity was investigated too. %26lt;br%26gt;The results have shown comparative mechanical properties of CBEM%26apos;s to HMA. Furthermore, the new CBEM%26apos;s with fly ash used as a replacement of filler achieved outstanding results compared with traditional CBEM with and without addition of OPC. Therefore, this paper introduces a new CBEM%26apos;s having outstanding mechanical characteristics, cost effective, and environmental friendly.
