Research Of Technique For Construction Quality Process Control Of Asphalt Pavements On The Highway

From the point of view of reliability, the main causes of the early distresses of asphalt pavement, besides overload, are inadequateness and unevenness of all kinds of indexes reflecting on construction quality. The current quality control emphasizes particularly on postmortem checkout, to improve construction, a new control method must be set up to implement aforehand control.Using reliability theory and quality control theory, the dissertation analyzed the reliability in time limit for a project, put forward the principle of control based on reliability, established process control method through introducing into Shewhart control charts, assured that the mean value of actual test value exceeded the design value and the variability was in allowable range to make sure that the reliability satisfied with the require of design.In the end, carried out the exploitation of suitable sampling device is guarantee of Construction Process Quality,inquiry into sampling method in engineering applied case.
