Study on Properties and Pavement Performance of Anti-Flaming and Warm-Mix Asphalt

Article Preview

Abstract:

In order to solve the problems of environmental contamination, large resource consuming and inflammability of asphalt mixture, this research chooses warm-mix agent and fire retardant to double modify the asphalt. After obtain the method to produce the anti-flaming and warm-mix asphalt through orthogonal experiment, its road property and anti-flaming property are valued. According to the experiment result, under the condition of cooling down 30°C of the mix temperature, the modified anti-flaming and warm-mix asphalt can increase the high temperature property of the asphalt mixture, but decrease the low temperature property and water stability characteristic of it. This asphalt has excellent anti-flaming characteristic, so it can decrease the property loss after being burnt.
