pavement structure
5.Technical level of the pavement structure is analysed qualitatively from the judgement factors to technical reasonableness, according to the pavement of bituminous concrete and cernet concrete, and to the new type pavement of steel fiber reinforced concrete and steel fiber reinforced roller compacted concrete.
7.Based on the analysis of the thaw settlement of the frost roadbed, the influence of the roadbed uneven settlement on the asphalt pavement structure is quantitative analyzed, and the calculating method of the additive stress arise from the uneven thaw settlement in pavement structure is firstly given.
8.In order to model the portland cement concrete (PCC) pavement performance, about 200 pavement sections with typical environment and maintenance level were selected from four districts of Guangdong Province, and then an investigation was made on their pavement structure pattern, distress, traffic volume and wheel path lane coefficient.
9.According to the spirit of the bituminous pavement technology seminar which convenes by the Ministry of Communicationson july 2005 in Nanjing,and combiningthe unique physical geography condition of north Zhejiang province,we have been caught on the detailed technical and economic appraisal comparison to seven stratification planes of the asphalt concrete pavement structure,recommending the best bituminous pavement structural design plan from 12 kinds of possible pavement structure design proposals suits Shenjiahu highway Jiaxing section characteristic.
10.Using the multilayered elastic system theory,under the style of double rounds uniform load,considering the thickness value of pavement structure courses and the stiffness change as well as the difference of interface condition,this paper presents the influencing factors of shear stress peak value and its change rule for semi-rigid base course asphalt pavement structure.
