邢临高速公路沥青碎石基层设计与施工ÃMDqy^Ùgbbs.3c3t.comÑvíMñ/`j 
随着国民经济的高速发展,交通量迅速增长,车辆大型化,严重超载等现象使沥青路面面临严峻的考验,许多高速公路建成后不久就不能适应交通的需要,早期破坏的情况时有发生。为缓解高速公路重载交通下的动水压力,我国开始应用推广以沥青碎石为代表的柔性基层。沥青碎石基层可以增强路面排水能力,减少沥青层的温度收缩裂缝和防止反射裂缝的发生,改善路面使用性能,提高其使用寿命。 ÃMDqy^Ùgbbs.3c3t.comÑvíMñ/`j

邢临高速公路是河北省“四纵、四横、十条线”公路网主骨架的重要组成部分,是河北省“十五”期间重点公路建设项目。全长104.64km,双向四车道,路基宽26m,设计车速100km/h。邢临高速公路在K0+000—K15+600段,进行了柔性基层沥青路面铺筑试验,选用沥青碎石用作上基层材料。 ÃMDqy^Ùgbbs.3c3t.comÑvíMñ/`j

沥青碎石基层即沥青稳定碎石类沥青混合料,其设计的基本的思路是保证沥青混合料中具有足够的粗集料,使之具有很好的高温、力学性能,按其设计的空隙率大小可以分为3种:开式(排水式基层,设计空隙率在15%以上)、半开式(设计空隙率在8%~15%之间)、密实式(设计空隙率在3%~8%之间),由于本项目作为高速公路基层,因此采用密实式的沥青混合料。 ÃMDqy^Ùgbbs.3c3t.comÑvíMñ/`j

原材料质量是影响路面质量、使用寿命的重要因素。优质的原材料是保证沥青混合料具有优良路用性能的先决条件,为了满足气候环境与交通对路用性能的要求,必须做好原材料的选择。通过测试沥青、石灰岩粗集料、细集料和矿粉等材料的性能和技术指标来检测材料是否满足规范要求,从而完成原材料的选择。 ÃMDqy^Ùgbbs.3c3t.comÑvíMñ/`j

集料是沥青混合料的关键材料之一,其力学性能是决定混合料强度特性的最重要因素,它的颗粒形状不仅影响混合料的构架,也直接关系到混合料的抗车辙能力与抗疲劳性能等材料特性,此外,集料与沥青的粘附等级对混合料强度的形成也起关键作用,因此选择优质的集料是沥青混合料具有优良路用性能的重要保证。本项目采用邢台太子井正大石料场,经初步破碎至50~100㎝拳石,运至存料场进行二次加工破碎,其几何形状和含泥量指标都优于《规范》要求的标准。 ÃMDqy^Ùgbbs.3c3t.comÑvíMñ/`j

初压:第一遍先用胶轮碾压一遍,再用YEC10L双钢轮压路机碾压一遍,驱动轮朝向摊铺机,静前进,振动返回,碾压路线、方向不能突然改变,往返转折点应错开成阶梯形,钢轮压路机紧跟胶轮压路机进行碾压,要求钢轮压路机与胶轮压路机之间错开两轮。 ÃMDqy^Ùgbbs.3c3t.comÑvíMñ/`j

横缝与铺筑方向垂直,形成一条碾压密实的边缘,下次摊铺前,在上次末端涂补适量粘层沥青,在碾压横接缝时先纵向后横向碾压,将压路机位于已压实的面层上,错过新铺层15cm,然后每压一遍向新铺层推进15-20cm,以推进到压路机轮宽度的1/3处进为止,改为正常碾压,在碾压时由专门人员用三米直尺检查接头处,发现问题及时处理保证接头部位的平整度。注意上、下层的横缝要错开至少1m的距离。 ÃMDqy^Ùgbbs.3c3t.comÑvíMñ/`j

从试验检测结果看,沥青碎石的高温性能比较好,水稳定性良好,但在有级配碎石的基层强度和刚度稍微差一些。车辙试验动稳定度比较高的原因可能是混合料粒径较大;从施工性能来看,混合料由于粗料多,容易出现离析,因此要从生产能力、施工工艺上严格控制。 ÃMDqy^Ùgbbs.3c3t.comÑvíMñ/`j

在我国柔性基层使用很少,近两年才开始一些研究。山东、山西、江苏等省进行了柔性基层研究,我省也在衡德高速公路铺筑了试验段。河北省高速公路建设正值建设高峰期,为了预防沥青路面的早期破坏,延长公路的使用寿命,使河北省的高速公路建设投资效益达到最大,进行柔性基层的研究是非常有必要的。采用柔性基层结构,使工程造价较普通半刚性基层有所增加,但是随着时间的增长,其优良的使用性能会逐渐显现出来,大幅度降低路面的养护维修费用,从长远利益来看,柔性基层具有更好的经济性能。 ÃMDqy^Ùgbbs.3c3t.comÑvíMñ/`j

另外,柔性基层在以后路面的修复中,柔性基层材料可以完全被利用,不但可以大大降低维修费用,节约能源,而且可以减少环境污染,因此采用柔性基层具有更好的经济和社会效益。ÃMDqy^Ùgbbs.3c3t.comÑvíMñ/`j
