Urban Road Reconstruction Engineering Design

Traffic with the development of modern society,the society growing,most of the status quo of road have been unable to meet the increasing traffic demand,urban road reconstruction project number increase sharply,therefore,have a plenty of road level of ascension,have a plenty of the expansion of construction scale,have a plenty of facilities need to renovate old,also have a plenty of road network planning adjustment,a new expressway the status quo of the old route.For various types of reconstruction projects,engineering design from more save investment,reduce the Angle of the impact on the surrounding land,consider using path reconstruction,but as a result of road area,the environment and the road itself function orientation is different,lead to all kinds of road engineering feasibility of implementation cannot treat as the same,at the same time for urban road reconstruction engineering standards are not applicable situations,in practical engineering,the engineering practical experience has many shortcomings.Therefore,the research on the design of urban roads is very important.This paper theoretically analyses the measures of the renovation,and based on the water west road reconstruction project,flat vertical linear combination of the renovation,the old and new embankment splicing,old pavement detection,old pavement overlay,both the traffic organization during the use of ancillary facilities and the construction design aspects to discuss in detail,to shorten the design cycle of construction projects,and optimizing the design scheme,improve the quality of design provides conditions,through in-depth study,in this paper,the following conclusions:1)analyzed the urban road reconstruction project,the vertical design features,get the following conclusion:the reconstruction project combined with the actual project their own characteristics,horizontal alignment on the premise of meet the current path specification,as far as possible longitudinal linear fitting status road flat,can achieve the goal of reasonable and economic.2)the old road subgrade pavement has a different degree of use value,for detailed investigation of the status quo is the basis of rebuilding roads,is an essential part of the reconstruction project of a link.3)the quality of the roadbed is largely determined by the service life of the highway.The reasonable use of the method of the method of using the method of the paving method can prevent the surface of the road to crack twice.4)in urban road reconstruction project as the research object,the paper sums up the implementation of the road pavement reconstruction steps:according to the basic data,carries on the analysis,find reasons of these diseases,and targeted diseases treatment measures,and then combined with the project requirements,to develop solutions that add a store,in pavement design,determine the pavement type,pavement materials.5)the reform and utilization of the existing road affiliated facilities can meet the principle of improving design quality and reducing cost.6)The reasonable use of traffic organization and management during construction can reduce the effect on the current road,which is more important in the road improvement.Through the actual validation plan,suggest that through the above theory can utmost reduce the cost of renovation,the outcome of the paper can offer reference for road reconstruction project.
