本文以湖南省益阳至常德高速公路项目为依托，以提高水泥混凝土路面使用性能为目标，就水泥混凝土路面结构组合、路面排水系统、缩缝设置传力杆、桥头跳车问题的防治等方面开展研究和工程实践，取得了丰富的研究成果，如研究采用了更合理的路面结构组合，设置了较完善的路面排水系统，在国内高速公路上率先全面采用缩缝加传力杆技术，对所有桥涵构造物台背全部采用刚柔过渡技术处理桥头跳车问题等。

Compare with the general road, bridge pavement has special structures, such as orthotropic bridge system and light-minded asphalt surface. The pavement diseases are resulted from the influence of environment climate and temperature.

桥面铺装不同于普通的高等级路面，由于其结构的特殊性(正交异性桥面体系及轻薄的沥青面层等)，亦受外界气候和温度的影响，因而很容易产生各种病害。

Thirdly, with FEM analysis software ANSYS, this paper has fulfilled appropriate pavement FEM models. Selecting right loading locations and parameters, this paper has simulated contact behaviors of limited dimension cement concrete pavement with joints afterwards. The mechanics response results and load transfer ability results of matchboard joints have obtained and the effect of reinforcing steel bars has gained too.

As for the construction of concrete pavement of highway, our corporation is bold in innovations, overcoming the common fault in the construction process. The coincidence rate of the evenness of the concrete pavement is 100%, and the mean square value is 0.90mm, which reach advanced domestic standards.

在公路水泥混凝土路面施工方面，大胆创新，克服了施工中的通病，混凝土路面平整度合格率100%，均方差平均为 0.90mm，达到国内先进水平。

The pavement system is modeled as a plate extent on a viscoelastic foundation, and the triple Fourier transform is used to analyze the dynamic strain response of rigid pavement subjected to moving vehicle loads.

把刚性路面建模为黏弹性地基上的板，用三次富立叶变换的分析方法分析了移动车载下刚性路面板底动态应变的响应。

To analyze the response of pavement structure under moving loading, a quarter vehicle model with single freedom degree and unevenness model are established. The dynamic loads are calculated through combining different pavement conditions and speed. When the incentive frequency which is passed to vehicles by the road is close to its own vibration frequency, vehicles will produce the greatest dynamic load.

为了分析路面结构在行车动荷载作用下的力学响应，建立了单自由度1/4车辆模型和以正弦曲线模拟路面不平整度的模型，通过将不同路面状况和行车速度的组合，分析车辆在各情形下所产生的动荷载，发现路面传给车辆的激励振动频率接近车辆自身振动频率时，车辆对路面产生的动荷载值最大。

Image analysis based on coarse aggregate shape and morphology assessment has been of recent research efforts to successfully indices to results from manual testing methods as well 3 as to pavement response and performance. The objective of this study is to to observes the moves of coarse aggregate of stone mastic asphalt and dense asphalt concrete by using image analysis technique.To establish the model of coarse aggregate moving behavior and asphalt pavement rutting.

本研究计画由载重过程，以影像处理分析技术观察SMA 级配及密级配粗粒料移动轨迹变化，以定量描述SMA 级配粗粒料构架形成机制、抗车辙能力成因、粗粒料材料形状组合因子偏差等影响，建立粗粒料移动轨迹与车辙量之行为模式，深入了解SMA 材料载重行为，俾供应用於公路及机场铺面能完全发挥其特性。
