1、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

2、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、

3、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

4、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基层粒径不大于37.5mm,底基层最大粒径文档编码:CS7B6L4A10K9 HF1J9P6I3F9 ZM5M3Z4Y8D4文档编码:CS7B6L4A10K9 HF1J9P6I3
