Abstract

This paper involves a case study which has been carried out to know the effect of e-quality control in Highway construction on the tolerance limits of WMM and DBM.  The existing tolerance limits have been kept keeping in view the normal system of quality control and permits higher range of variations for acceptance. This study involves the solution of a real life problem faced by an engineer during the construction of a highway.  In this paper, we present a methodology using e-quality control system and updated machinery to see its effect on the tolerance limits of WMM and DBM.  To understand the methodology a field case study is presented here.

Keywords: e-control, WMM, DBM, tolerances, GPS, Consumption, VTS etc.
