低造价县乡道路路面结构性能的室内试槽试验研究

在室内试槽内铺筑足尺寸县乡低造价道路的典型路面结构,通过施加实际行车荷载作用,模拟路面的实际工作状况.通过测定路面结构各层位的应力及路表弯沉等相关性能指标,分析考察路面结构的各项路用性能与轴载作用次数的响应.验证推荐的典型结构的适用性,为县乡低交通量道路路面设计提供依据.

Eexperiment Research of the Pavement Structure of the Low Cost County Roads in the Test Slots

The typical pavement structure models of the low county roads are built in the test slots.The actual work condition of the pavement is imitated by acquiring a large quantity of loading and the breakage pocess in experiments.The related function parameters,such as the stress stain rut depth,are measured by the experiments and research testifyings in the test slots in order to establish whether the four kinds of pavement structure can satisfy the cowgirl transportation level requests or not.The pavement structure guidebook that are established by the actual roads build experiments is reasonable on the technique.
