Introduction Technology for making asphalt concrete deice and melt snow by electrothermal effect is through cutting down the resistivity of asphalt concrete after mixing some conductive materials.
Experimental Methods 2.1 Raw materials Asphalt: Guochuang heavy-duty type (AH-70) asphalt made in Hubei province was selected with penetration of 66 (25◦C，100g, 5s), softening point of 49.5◦C and ductility of 150 (5 cm/min, 15◦C).
The traditional fatigue theory is a phenomenology method, which adopts fatigue curve to predict materials’ fatigue properties.
