Warm-in-winter-and-cool-in-summer type double-phase-change self-temperature-adjusting asphalt mixture
The invention discloses a'warm in winter and cool in summer 'type double-phase-change self-temperature-regulating asphalt mixture, which is characterized in that a high-temperature phase-change material and a low-temperature phase-change material are compounded and doped into the asphalt mixture, so that the asphalt pavement has the functions of delaying the pavement heating rate under a high-temperature condition and delaying the pavement cooling rate under a low-temperature condition; the double-phase-change temperature adjusting effect that the asphalt pavement is warm in winter and cool in summer is achieved. Comprising natural mineral aggregate, asphalt, mineral powder and a double-phase-change material, the mass fraction of each raw material is 85-90% of the aggregate, 4-6% of the asphalt, 4-6% of the filler and 1-3% of the double-phase-change material. The lowest temperature peak value of the'warm in winter and cool in summer 'type double-phase-change self-temperature-adjusting asphalt mixture is about 2 DEG C higher than that of a common asphalt mixture, and when the temperature of the common asphalt mixture is reduced to 0 DEG C, the temperature of the double-phase-change asphalt mixture is 2-3 DEG C, which shows that the'warm in winter and cool in summer' type double-phase-change self-temperature-adjusting asphalt mixture has good temperature adjusting effect and ice and snow melting effect.
本发明公开了一种“冬暖夏凉”型双相变自调温沥青混合料，通过将一种高温相变材料及一种低温相变材料复配后掺入沥青混合料中，赋予沥青路面在高温条件下延缓路面升温速率、在低温条件下延缓路面降温速率的功能性，实现沥青路面冬暖夏凉的双相变调温效果。包括天然矿质集料、沥青、矿粉及双相变材料；各原料的质量分数为：集料85～90％，沥青4～6％，填料4～6％，双相变材料1～3％。该“冬暖夏凉”型双相变自调温沥青混合料的最低温度峰值比普通沥青混合料高2℃左右，且当普通沥青混合料降温至0℃时，双相变沥青混合料的温度为2～3℃，说明该“冬暖夏凉”型双相变自调温沥青混合料具有良好的调温效果及融冰化雪效果。
