Optimization of the epoxy resin water dispersion for modification of the RAP cold recycled mixes
Year: 2019
Type: conference-paper
Abstract: This article presents the results of studies to optimize the composition of water dispersion of epoxy resin for the modification of RAP cold recycled mixes. The resulting water dispersion is easily combined with the bitumen emulsion and can be easily applied in the preparation of cold mixes. This kind of modification will significantly improve their reliability and durability and to closer in magnitude to the properties of hot asphalt concrete widely used for the construct of road pavements. In order to improve the efficiency of the modification process, the process of emulsification of epoxy oligomers in the presence of nonionic surfactants and further application of the obtained dispersions as a component of bitumen emulsions used for the preparation of RAP cold recycled mixes is justified. This kind of integrated approach to the selection of the composition of water dispersion of epoxy resin provided a higher level of its interaction in the formation of elastic and viscous bonds of increased strength in the formation of the structure of composites based on asphalt, bitumen emulsions and cement.
