第 1 章城镇道路工程一、城镇道路工程结构与材料 (1)以道路在城市道路网中的地位、交通功能为基础,同时考虑对沿线的服务功能,将城镇道路分为四类:快速路、主干路、次干路、支路 以地位、交通功能、服务功能分:快支主次 快速路:完全为交通功能服务,解决城市大容量、长距离、快速交通的主要道路;主干路:交通功能为主,城市道路网的主要骨架次干路:城市区域性交通,为区域交通集散服务,兼服务功能支路:以服务功能为主 (2)按结构强度分:高级路面(快速路、主干路)?水泥砼路面(30 年);沥青砼 注意考试的时候可不能这样简写砼,要写全:混凝土 、沥青碎石、天然石材(15 年)次高级路面(次干路、支路)?沥青贯入式碎(砾)石(12 年);沥青表面处治(8 年)(3)按力学特性 双控 1 分:柔性路面 黑色路面,破坏取决于极限垂直变形和弯拉应变?各类沥青类路面,破坏取决于极限垂直变形和弯拉应变;刚性路面?水泥砼路面,破坏取决于极限弯拉强度 白色路面,破坏取决于极限弯拉强度;是混凝土配比依据 。(4)?(11)沥青路面结构组成与特点 (4)城镇沥青路面结构由面层、基层和路基组成;(5)行车荷载和自然因素对路面的影响随深度的增加而逐渐减弱,对路面材料的强度、刚度和稳定性 关键词?强度,刚度,稳定性;桥梁中多次用到,注意积累 的要求也随深度的增加而逐渐减弱。各结构层材料的回弹模量应自上而下递减;(6)面层、基层的结构类型及厚度应与交通量相适应。(7)基层的结构类型可分为柔性基层、半刚性基层,在半刚性基层上铺筑面层时,城市主干路、快速路应适当加厚面层或采取其他措施 土工合成材料:玻纤网和土工格栅;旧路面的改造:白+黑,黑+黑 以减轻反射裂缝 基层开裂导致面层开裂;基层开裂原因:含水率(干)、温度(冻)。(8)路基与填料高液限黏土、高液限粉土及含有机质细粒土 路基施工中还有不适合做路基填土的有:生活垃圾土、腐殖土、淤泥、冻土或盐渍土、有机土、沼泽土、泥炭土,不适合做路基填料。因条件限制而必须采用上述土做填料时,应掺加石灰或水泥等结合料进行改善。岩石或填石路基顶面应铺设整平层。厚度一般10-15?基层是路面中的承重层,主要承受车辆的竖向荷载。应根据道路交通等级和路基抗的冲刷能力来选择基层材料。湿润多雨地区,宜采用排水基层;底基层可采用级配粒料、水泥稳定粒料或二灰稳定粒料。(9)常用的基层材料无机结合料:石灰稳定土类基层、水泥稳定土类基层、二灰稳定土类基层嵌锁型和级配型材料:、级配砂砾和级配砾石基层可做城市次干道及其以下道路、级配碎石和级配碎砾石基层可做城市快速路、主干路、次干路及其以下道路。所有道路的基层均可使用
