【摘要】 大空隙开级配排水式沥青磨耗层(Open-graded Friction Courses,简称OGFC)具有良好的排水、防滑、降低噪声等性能,适合在多雨地区高等级公路上应用。然而,国内对OGFC路面研究起步较晚,研究进展也不大,目前可供应用或借鉴的成果不多。鉴于此,本文通过查阅大量国内外文献,掌握了有关该问题的国内外研究情况及动态。在分析OGFC路面的特点基础上,提出了OGFC混合料对原材料的技术要求以及配合比设计目标,结合配合比设计目标,对OGFC混合料矿料级配、最佳沥青用量进行了研究,并提出了OGFC混合料配合比设计方法通过大量室内试验,对OGFC混合料的力学性能、透水性能、高温稳定性能、低温稳定性能及水稳定性能等进行了研究,结果表明OGFC混合料具有较好的路用性能。最后,试验路研究表明,OGFC路面具有良好的抗滑性能和排水性能,并通过试验路铺筑提出了OGFC路面施工工艺。更多还原

【Abstract】 OGFC--Open Graded Asphalt Friction Course with the performance ofdrainage、anti-skid and low-noise apply to many highways in rain region. However, the research of OGFC is only on it’s start and the conclusion of it is not much which can be use for reference in our country. In this situation, the paper refered to the documents inside and outside and mastered the situation and developments of the interrelated question. On the base of the analysis of OGFC pavement character, the paper put forward the OGFC mixture demand of raw materials and the aggregate gradation design target. Base on the gradation design target and through large experimengs , the paper resdarch the OGFC aggregate gradation , optimum asphalt content, OGFC mechanical performance, dank performance, high-temperature stability, low-temperature stability and water stability performance and put forward the method of OGFC mix design .The result make it clear that OGFC mixture has better pavement performance. Better skid resistance. Better drain performance . In the end , the paper put forward construction technics of OGFC through the testing pavement.更多还原
