The Overhaul Road Countermeasures And The Analysis Of Typical Pavement Structure In Shenyang Rural Road

In this paper based on the former research, at home and abroad to the existing technology and road asphalt pavement overhaul technology assessment are analyzed, and the key to rural highway asphalt pavement technology assessment are summarized. On the rural highway asphalt pavement of common technology assessment index, evaluation method and evaluation rating system are analyzed in detail, combined with the practical project, of the asphalt pavement for rural highway pavement condition index PCI and road surface structure strength index of the evaluation of the PSSI rank standard adjustment, and puts forward the basic readiness more close to actual evaluation index, for the rural highway asphalt pavement.this technical status evaluation classification and overhaul decision provides the judgement basis.The asphalt pavement of original on the reasonable evaluation, based on different pavement damage condition, puts forward the corresponding technical countermeasures several overhaul, and its economy, to adapt to the traffic, the advantages and disadvantages of existence are analyzed in detail. At present the rural highway asphalt pavement overhaul scheme is still mainly determined by the restriction of the funds, the determination of the overhaul scheme in the process of the main consideration its economy, and to ensure that the overhaul of the asphalt pavement structural and functional requirements. And combined with rural highway asphalt pavement overhaul of actual project, the asphalt pavement of original on the reasonable evaluation, based on different pavement damage condition, puts forward the corresponding technical countermeasures several overhaul, and its economy, to adapt to the traffic, the advantages and disadvantages of existence are analyzed in detail.This paper based shenyang road repair engineering, the selection of the design schemes of some pavement structure, a finite element model, with ABAQUS finite element analysis software mechanical calculation, and the calculated results are analyzed, based on the result of this paper, recommend several rural highway asphalt.
