AC-13、AC-20沥青混合料骨架密实级配范围研究
|
摘要
随着我国高速公路的迅猛发展,沥青路面得到了广泛的应用,对其也提出了越来越高的要求。高速公路取得量的飞跃的同时,在质的问题上还存在着很大的隐患,我国沥青路面出现的各种早期病害与沥青路面各结构层沥青混合料级配设计不当存在密切的关系。由于我国地域辽阔,各地区气候条件及交通环境差异却很大,规范作为一个全国性的技术指导与控制标准必需涵盖所有情况,但是给出的较大级配范围却给每一个具体工程的混合料设计带来了很大的难度,如何寻找出最适合每一个具体工程项目的设计级配范围是我国工程技术人员面临的现实问题。
本论文针对沥青路面表面层及中面层所采用的典型集料,以4.75mm作为粗细集料的分界线,对集料进行分级组合捣实密度试验并根据所得到的粗集料间隙率以最紧密堆积为原则确定粗集料的级配范围;同时对每组捣实密度试验的方案进行CBR试验,用CBR试验来评价骨架,认为CBR值越大,骨架越强;在兼顾两个指标择优确定最佳的粗集料级配范围;细集料则以填充且不对粗集料产生干涉为原则在考虑空隙率为4%的基础上结合粗集料间隙率计算出细集料总的体积比,同时考虑细集料不参与混合料骨架形成为减少试验工作量采用均匀分布,其级配范围则结合施工技术规范容许波动范围予以确定。由此得到的矿料级配范围并对AC-13、AC-20沥青混合料配合比进行优化设计,通过对体积指标及高温稳定性和水稳定性进行综合评价优选出最佳的级配曲线。该设计方法有别于国内外流行的其他设计方法,提供了沥青混合料级配设计的新方法,对于推动我国沥青路面的发展起到了一定的作用。
Asphalt pavements have been widely used along with the fast development of highway,which put forward higher quality requirement for it. With the highway acquire quantity development,it also exists some hidden trouble in quality. Because our country is vast territory, and regional climate conditions and traffic conditions are very different, as a national standardized technical guidance and control standards necessary to cover all situations. but given the larger class with a specific scope of work has given each of the mixture designed to bring a lot of difficulty. The realistic question that the general engineer’s and technicians faced is how to chose the most suitable design gradation scope that apply to each project in a wide scope of gradation.
This article focused on the typical aggregate of the up layer and the middle layer, which is used in asphalt pavement. 4.75mm as the boundary of the fine and coarse aggregate, it will carry on the graduation combination ram density experiment, using the gap of coarse aggregate which is obtained from the experiment as a appraisal target. Then using the closest heap as the principle to decide the gradation scope of coarse aggregate.At the same time taking the CBR test,the test of combination is the same with the ram test. CBR test used to evaluate the coarse aggregate skeleton, the bigger value of CBR test, the stronger the skeleton. The principle of the fine aggregate is filling and does not interference with coarse aggregate structure .It unify the Superpave’s design thought and 4% of design’s percentage of gap rate determination then combine with the coarse aggregate to calculate the total rate of volume of fine aggregate. The mutual proportion of fine aggregate will use distribution; its gradation scope will unify the construction technology standard to allow the undulation scope which is determined. From this obtains aggregate gradation scope and the optimized design of the rate of gradation of AC-13、AC-20 asphalt mixture. Though the synthesis appraisal among the volume target and the high temperature stability and the water stability to choose the best grading curve. This design method is difference from other popular design methods among the domestic and the foreign counties, put forward a design method for Asphalt mixture. This will do helpful to the development of the asphalt pavement in our nation.
