| 摘 要： | 高模量沥青混凝土(HMAC)作为一种新型路面材料,具有模量高、抗车辙性能好、对低温开裂及温度疲劳开裂敏感性不强等优点,对于提高路面抗车辙能力非常有效。该文利用通用有限元软件ANSYS,对设置高模量沥青混凝土层的半刚性基层沥青路面的荷载响应进行数值模拟分析,结果表明高模量沥青混凝土可显著抑制车辙的产生,并推荐出高模量沥青混凝土层的模量和厚度的合理范围。

| Abstract: | AS a new pavement material,the high modular asphalt concrete(HMAC) can effectively improve the road capacity of rutting-resistance with its high modulus,good rutting-resistance,weak sensitivity of low-temperature cracking and the temperature fatigue cracking.The general finite element software ANSYS is used in this paper to carry the numerical analysis of the loading response of the semi-rigid base asphalt concrete pavement with the high modular asphalt concrete cover.The result indicates that HMAC can significantly inhibit the emergence of asphalt pavement rut,the reasonable module scope and thickness of the high modular asphalt concrete cover is recommended. |
