A Study on Incorporating the Tabular CUSUM and Shewhart Control Chart to Monitor Road Surface Quality

By 

Abstract

In this article, the “Tabular CUSUM (Cumulative Sum) Charts statistic method is employed to analyze the strength quality control of ready-mixed concrete for rigid pavement, for which the CUSUM is also used to analyze and monitor the micro changes of process mean for the strength of the ready-mixed concrete. The result of analytical study supports that the CUSUM statistical analysis skill is more sensitive than the Shewhart Control Chart in terms of designed mixing ratio parameter, water-cement ratio, and admixtures analyzed under the same concrete strength. When micro changes are presented in continuous mean strength value of the ready-mixed concrete, it can detect the continual changes of the concrete quality in a more accurate way. By combining the CUSUM statistical analysis and Shewhart Control Chart, higher accuracy of the quality control analysis could even be achieved in order the enhance quality control performance when pouring the ready-mix concrete on rigid pavement
