摘要
本人参加了河南省交通厅批准立项的“沥青混合料路面抗裂性能研究”(计
    划编号:98G403) 课题的活动,本文是结合该课题的研究工作编写的。
    本文研究的主要内容是:沥青混合料低温开裂机理,沥青混合料低温开裂影
    响因素,沥青橡胶碎石,玻璃纤维沥青碎石的高温抗压强度,低温劈裂强度,抗
    滑性能及其施工工艺,技术与经济比较等,探索新型的沥青路面结构组合。
    通过在室内对沥青碎石,沥青橡胶碎石,玻璃纤维沥青碎石进行了马歇尔试
    验和低温抗裂强度试验,得到了各种试验数据,应用数理统计的方法进行试验,
    得到了各种试验数据,应用数理统计的方法进行试验数据的处理,通过对比分析,
    提出了三种沥青碎石的最佳配合比。在试验室和沥青混合料拌和场摸索了沥青橡
    胶碎石的摊铺工艺。
    通过试验研究认为:玻璃纤维沥青碎石的技术性能不如沥青碎石好,但路用
    弹性性能较好,如能解决拌和工艺问题,调整纤维丝的品种,增大其直径,其路
    用性能仍值得探讨,沥青橡胶碎石结构层具有变形性能和抗裂性能良好,空隙率
    小,防水性能好,热稳定性较好,施工工艺简单的特点,因此,沥青橡胶碎石是
    二级及二级以下公路因疲劳而开裂的沥青路面的良好罩面材料,也是防止半刚性
    基层收缩裂缝反射的良好结构措施,在沥青类路面面层和半刚性基层之间夹铺沥
    青橡胶碎石薄层,虽然造价比夹铺土工布高,但其施工工艺,抗裂性能和防水性
    能均优于土工布,不仅可以大大减少半刚性基层材料的反射裂缝,延长路面使用
    寿命,而且可能适当减薄沥青混合料面层的厚度,虽然初期造价有所增加,从长
    远来看,具有十分重要的技术和经济意义。
    该成果对公路沥青路面的养护和设计具有重要的实践指导作用,对于减少公
    路沥青路面的养护费用,延长路面使用寿命具有重要的经济和社会意义。
I participated in the research group of "study on crazing -resistance performance of Asphalt mixture pavement"(plan No: 98G403) as approved by Henan Provincial Communications Department. The thesis is prepared in combination with the study of such research.
    The main contents that are researched in the thesis are : asphalt mixture low temperature crazing principle , the influencing factor of asphalt mixtures low temperature crazing ,asphalt-rubber macadam , the pressure-resistance intensity , the crazing high temperature , the smooth-resistance and construction technology ,the technological economical compare and so on , exploring the new-type structural combinations of asphalt pavement.
    Through the Marshall experiment and the low temperature crazing-resistance intensity experiment , which work on the asphalt-rubber macadam , fiberglass asphalt macadam indoors ,we have got various kinds of experimental data , carrying out experiment by means of the method of mathematical statistics ,we have got various kinds of experimental data .dealing with the experimental data by means of the method of mathematical statistics , through contrast and analyzing , we have put forward the best suitable rate of the three asphalt macadam ,hi the laboratory asphalt macadam ,In the laboratory and the asphalt mixtures blending gathering plane , we have groped after paving technology of the asphalt-rubber macadam .
    Through the experimental research , we think :the technological capacity of fiberglass asphalt macadam if weaker than asphalt macadam ,however ,if use elasticized capacity to solve blending technological problem .adjust the breed of fiber silk , extend its diameter , its paving capacity is still worth exploring , Asphalt-rubber macadam structure lager have good deformed-become capacity and crazed-resistance capacity , small gap rate .good water-resistance capacity ,good hot-stability and simple construction technology .therefore .pitch rubber spall is a good cover material which is suitable for the second class or lower whose asphalt pavement has split open because of fatigue .and is the good structural measure of preventing half-rigidity grass-roots unit shrink-rift reflecting .pave a thin layer of pitch rubber spall between asphalt -type
    
    
    
    pavement layer and half-rigidity basic level ,although the cost of building is higher than paving Togongbu in the middle , the construction technology, crazing-resistance and water-resistance are better than Togongbu , not only could reduce greatly the reflex of half-rigidity grass-roots unit material, long then the use lifespan of pavement, but also it is possible to reduce suitably the thickness of asphalt mixture layer , though the cast of building in the early days becomes more ,in the long-term opinion, it have fully important technological and economical significance .
    The achievement have important practical guided action to the maintaining and design of the asphalt pavement , for reducing the maintaining fee of the asphalt pavement and lengthen the use lifespan of the pavement, it have important economical social significance .
