摘要：
This paper reports the experimental test results of a research project aimed at developing a new cold bituminous emulsion mixtures (CBEM'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. The main objectives of the experiments were to investigate the improvement in mechanical properties of CBEM'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. The results have shown comparative mechanical properties of CBEM's to HMA. Furthermore, the new CBEM'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's having outstanding mechanical characteristics, cost effective, and environmental friendly. (C) 2012 Elsevier Ltd. All rights reserved.
