摘要

The general trend of highway networks expansion is still in continuing development. This expansion is mainly achieved by using of Hot Mix Asphalt (HMA) Technology, which is uneconomic and unsustainable solution for future with obvious recognition of high energy consumption and high CO_2 emissions. Thus, developing the characteristics of sustainable paving technology such as Cold Bitumen Emulsion Mixtures (CBEM) is in high demand. However, Half Worm Bituminous Emulsion Mixture (HWBEM) is a CBEM subjected to moderate heating energy prior to compaction process. This paper aims to evaluate the enhancement of crack resistance of HWBEM by using of low energy heating technique (i.e., microwave). The effect of incorporation of different crushed glass waste as fine aggregates instead of virgin fine aggregate (VFA) were also investigated. Then, indirect tensile strength and creep compliance tests were used with optimum heating time to specify the enhancement in cracking resistance. Test results have cleared that the procedure followed for preparing HWBEM was efficient to produce asphaltic mixture with properties superior to CBEM in term of crack resistance. Thus, the results revealed the significant of low energy heating to produce new promising paving technology.
