Research On Flexible Base Engineering Quality Control

With the rapid development of highway construction, But some roads into operation prematurely occurred diseases, need to invest more conservation funding. The destruction of roads and construction quality, environment and vehicle load, etc. have a greater, but also with our high-speed road single use of semi-rigid base also has a certain relationship. Solve this problem, the flexible base structure of the road once again receive attention, research began to increase on the flexible base, due to the small domestic application of the flexible base, the paper focuses on ATB-30flexible base mixing and paving in the process of quality control, hoping to give the flexible base construction help.First of all, Analysis of the four tenders ATB-30indexes of the raw materials and grading. Meaning and cold silo mixing station calibration calibration method, the dynamic calibration method calibration of cold silo mixing station obtained the curve of the motor speed and cold silo production and analysis of the calibration curve parameters and the production of cold silo relationship, according to the relationship of each of the cold hopper motor speed output curve draw cold silos motor speed.Secondly, Through the analysis of hot material screening results for each tenders, Determine the vibrating screen sieve size of the project; Through the establishment of the model shaker screening efficiency changes graded, graded when mixing station shaker screening efficiency changes significantly, and the hot hopper vibration sieve screening efficiency to reduce the degree of impact on the gradingscreening efficiency, improve the degree of influence of graded according to the calculation results obtained, when mixing station shaker screening efficiency is stable within a certain range of fluctuation, in order to produce a mixture in line with the fluctuation range of gradation.Finally, Summarizes the segregation of the testing methods and evaluation standards, and flexible base construction often segregation analysis, a reasonable solution for different segregation Finally, analysis of ATB-30flexible base construction characteristics of the selected construction equipment andpaving test road test road to determine the construction parameters.
