北京东三环主路大修将在本月开工 采取夜间施工模式

东南四环辅路大修进入沥青路面摊铺阶段

东三环主路大修将在本月开工

今年市管道路大修第一批工程进入沥青路面摊铺阶段,包括东南四环辅路、京通辅路、西四南大街、东直门内大街等道路将于近期开始路面摊铺。为最大限度减少施工对市民出行的影响,大修工程采取夜间施工模式,所有工序安排在夜间0点至5点完成。

东南四环辅路大修凌晨开工

今天凌晨,记者在东南四环十八里店南桥以西路段看到,穿着橘黄色马甲的施工人员正挥舞着导流棒对来往车辆进行分流。一些工人正在清理路面井盖设施。1点45分,沥青铺装正式开始。据施工方介绍,预计到7月底,四环辅路大修工程将全部结束。

据介绍,为有效避免重复施工,减少“马路拉链”这个顽疾,在本次道路大修前协调热力、自来水、架空线入地等相关市政设施服务单位,将地下管线随本次道路大修一并实施,计划完成随路施工管线20余公里。

值得关注的是,在第一批道路大修的同时,路政部门将会同步进行步行、自行车系统整治和无障碍设施完善工作。在道路交叉口、桥下路口等位置铺设9000余平方米彩色非机动车道,起到警示机动车、规范自行车、分离人行的目的。通过大修工程共对60余公里步行、自行车系统进行了梳理和整治,提高绿色出行的安全性和舒适性。同时,还将对车行道上3000余座检查井进行加固处理,提升道路的舒适性。

四环步道宽度达到1.5米

为了优化慢行系统,此次四环辅路大修还将拓宽一些较为狭窄的人行步道。北京市城市道路养护管理中心工程管理科科长段文志向记者介绍,像南四环内环肖村桥西北角的一部分路段,由于路边有边坡存在,人行步道宽度仅30厘米,行人走在上面比较拥挤,此次大修将采取设置挡墙的方式,将人行步道抬高,也就拓宽了步道的宽度。此外,针对一些占用步道经营的报刊亭,大修过程中施工单位将会与报刊亭经营者进行协商,将其挪移到不影响行人通行的位置。大修完成后,东南四环人行步道将争取全线达到1.5米以上宽度。

新工艺提高舒适性

据北京市城市道路养护管理中心介绍,在四环辅路大修中,中面层采用了热再生沥青混凝土,通过对铣刨回的旧沥青材料进行筛分分析,按照一定比例添加到新沥青混凝土中,实现了旧路材料的循环利用,节约矿产资源。在进行道路病害处理时,采用乳化沥青同沥青混合料同步施工一体机进行铺筑,避免以往分步施工造成沥青混合料摊铺机械对黏层的破坏,提高层间黏结效果,保证结构强度,延长使用寿命。
