Abstract

The morphology and dynamic mechanical properties of epoxy modified asphalt(EMB) were studied using dynamic mechanical analyzer (DMA) and fluorescent microscopy (FM). DMA results showed that dynamic modulus and storage modulus reached a maximum value when 5 wt % epoxy resins were added. However, the dynamic modulus and storage modulus decreased, when the contents of epoxy resin are more than 5%. The FM analysis showed that epoxy asphalt has finished basically after the curing for 4 hours and has formed the epoxy network structure. The layered hydrotalcite and rubber powder are distributed evenly in the epoxy asphalt and form a stable continuous phase, when the epoxy resin content is more than 3%.
