彩色半柔性混合料路用性能研究

彩色半柔性混合料是一种在开级配沥青混合料中填充水泥胶浆而形成的兼具沥青路面与水泥混凝土路面优点的彩色复合路面。利用车辙试验来评价彩色半柔性混合料的高温稳定性,用残留稳定度和冻融劈裂试验评价半柔性混合料的水稳定性。结果表明,半柔性混合料具有优良的高温稳定性和疲劳性能,水稳定性较好。

Pavement performance study for colourful semi-flexible mixture

Semi-flexible pavement is generally described as open-graded asphalt concrete mixture filled with colorful cement grout and there are advantages of both flexible and rigid pavement. The wheel tracking device was utilized to measure its rutting resistance at high temperature, the retain stability and Lottman test were used to assess its water susceptibility. The results show that colourful semi-flexible mixture has excellent rutting resistance and fatigue resistance, its water susceptibility is also modified.
