Research On The Conformity Of The Quality Control Of Urban Road Construction

In the past few decades,at the same time of rapid development of the highway,the number of urban roads is also growing rapidly.At the same time,a lot of problems has been appeared.There are widespread problems such as early deterioration,poor durability and so on.In the construction process,due to the different materials,structures and construction process,the road will inevitably produce variability.It will directly affect the road comfort and safety during use,cause such as rutting,upheaval,subsidence and a series of early disease,reduce the service life of road surface.This paper mainly through the quality dynamic control and management of the road in the construction process,explore the key factors in the production process of asphalt pavement construction,control method for dynamic management and process of these factors,try to ensure the consistency of design and construction,improve the stability of construction quality,reduce the variability in the process of construction,to ensure the pavement quality and prolong the service life of the road.This paper relies on the Chongqing road project in Qingdao City.Based on the characteristics of the construction process,the paper puts forward the main control indexes which affect the roadbed and pavement,and determine the impact of asphalt pavement construction quality of the key factors according to the material,structure,construction technology for complex testing.The establishment of the relationship between resilient modulus of subgrade and pavement layers site and the controlling index,in order to achieve by controlling the field Master Index to make the construction of resilient modulus of resilient modulus in accordance with the design requirements,improve construction quality,meet the design requirements.
