摘要
The waterborne epoxy modified cement asphalt mortars were prepared with varying content waterborne epoxy and a constant fluidity. The effects of waterborne epoxy emulsion on water/cement ratio,compressive and flexural strength,tensile bond strength,freezing and thawing damage,corrosion resistance of cement asphalt mortar cured for 7 and 28 d have been investigated. The results show that waterborne epoxy is very beneficial to the improvement of mechianical properties and durability of cement asphalt mortar. Waterborne epoxy can improve the flowing ability of cement asphalt mortar. With the increasing of waterborne epoxy content,compressive strength,flexural strength and bond strength all have increased obviously. The modified mortar shows higher resistance to corrosion and the freezing and thawing compared with control mortar.
