| 摘要： | Implementation of Quality Control and Quality Assurance (QC/QA) is necessary to ensure consistent and quality bituminous road construction in India. It should replace the present system of generally reporting "passing" test results only during construction, which is unacceptable and leads to premature failures. Quality control is the responsibility of the construction contractor who should prepare and execute a QC plan for the bituminous paving project. Quality assurance is the responsibility of the owner (such as NHAI, representative of NHAI, or a concessionaire). For quality assurance paving project is first divided into lots and sublots. Quality assurance is done with the help of Percent Within Limits (PWL) and pay factors (price adjustments), which are determined for each lot from test values of sublots. This paper describes the QC/QA system in detail and the way it should be implemented in India after some pilot projects. For QA a computer software program based on Excel has been developed at IIT Guwahati exclusively for this paper and is available online. With this program it is quite easy to calculate the mean, standard deviation, and PWL once the five sublot test results are entered along with the minimum and maximum specified limits for the test parameter. |
