摘要：级配类型决定了沥青混合料的空隙率和结构组成，并影响其路用性能。分别选择2种连续级配和间断级配，对上面层彩色OGFC-10的透水性及其影响因素进行研究。试验结果表明：4种级配类型的彩色OGFC-10均可获得良好的路用性能，且连续级配1与间断级配3组配彩色OGFC-10的透水性及其综合性能更优。

Abstract：The gradation types determine the void fraction and structural composition of the asphalt mixture，and affects its road performance. In this paper，two kinds of continuous grading and intermittent grading were selected to study the water permeability of the upper layer color OGFC-10 and its influencing factors. The test results show that the four graded types of color OGFC-10 can obtain good road performance，and the continuous grading 1 and intermittent graded 3 groups with color OGFC-10 have better permeability and comprehensive performance.
Key words：gradation type，color OGFC，permeable performance，void ratio
