The Preparation of Compound Modified and Emulsified Asphalt Mortar and its Micro-Analysis

The modification effects of the cement and the water-based epoxy resin on the asphalt emulsified mortar are studied. The result shows that with the cement content 30% and water-epoxy resin emulsified content 30%, the modified asphalt emulsified mortar which can replace cement mortar meets the demands of the relative criterions. When the temperature reaches 140°C, both the tensile bond strength and the shear bond strength decrease to 0.1 MPa. So it is feasible to recycle the decorative stone .The micro-analysis of the modified mortar are investigated by using IR and TGA-DTA, and its modification mechanism is also discussed.
