Due to the increase of road infrastructure around the world, its impact on the environment and scarcity of aggregates requires serious attention to construction of sustainable pavement which constitutes towards the use of cold mix recycled asphalt technology. Cold mix recycled asphalt with bitumen emulsion and Foamed bitumen is a technique still in development, which has proved to be very promising, both in economic and environmental terms. This technology saves energy, natural resources, reduces CO2 emissions as recycling is done at lower temperature and increases the amount of recycled materials. The objective of this review is to summarize the study on Foam Bitumen and Emulsion incorporating RAP in construction materials, which is a challenging task due to the heterogeneity of the materials. |
