摘要
近年来,随着我省农村经济大不断发展,农村公路建设也显得越发重要。在公路里程
迅速增加的同时,路面早期破损现象十分普遍,导致这一结果的直接原因是交通量的急剧
增加以及重载交通。
通过对辽宁省部分地区农村公路的实地调研,发现由于面层和基层间剪切的破坏引起
的路面推移现象十分严重,沥青路面推移现象成为我省农村公路最为典型的路面破损现象
之一,本文依托辽宁省交通厅科研项目《辽宁省农村公路养护技术政策的研究》,根据辽
宁省农村公路路况调查资料,对农村公路路面推移形成的力学机理进行深入的理论分析,
并以此探讨了防治路面推移现象的技术措施。
本文通过系统的归纳全国农村公路结构和养护现状,针对辽宁省不同的自然状况、气
候条件、水文地质情况、交通状况和土基条件,对辽宁省各地农村公路的基本结构进行归
纳,通过建立路面结构模型,对有限元模型进行沥青路面结构剪应力计算和分析,并从设
计和施工两个方面提出防治推移破坏的基本措施

Abstract
In recent years, with the development of rural economy in Liaoning province,
the building of the rural area highways also became more important. With the rapid
increase in highway mileage, the road early damage is widespread. the reason for this is the
direct cause of the sharp increase in traffic volume and heavy-duty transport.
Through the field surveys of rural roads in some places in Liaoning province, we found that
the slippage problem is very severe due to damages to the shearing between surface and base.
The slippage of asphalt pavement e one of the most typical phenomenon that road
damaged of rural highway in our province.
This article relies on the Liaoning munications Department, the research
that 《 Highway Maintenance Technology Policy Research of rural areas in Liaoning
Province》.according to the survey data of Rural Road traffic on rural roads in Liaoning
Province,mechanism of asphalt pavement slippage is analyses and the study on prevention
measure of slippage is controlled in the rural highway of Liaoning Province
This essay systematically summarizes the structure and maintenance’s now-in-position of
low-graded road nationwide and summary of the environmental and climatic features of various
areas in Liaoning province. By analyzing the oretically as well as providing ways of preventing
and decreas
