This study aimed to develop a generic methodology to quantify the risk and reliability of pavement and embankment design for Bangladesh considering the variability in design data. The study also aimed to develop a construction quality control procedure to reduce the variability in data. To achieve this aim, data were collected from field and laboratory testing from four of the country’s representative roads and a database was developed. The collected data were studied and their variability was quantified. To develop a suitable risk quantification methodology for Bangladesh, the existing methods were investigated and compared for their appropriateness in connection with the proposed analytical pavement design method and the prevailing conditions. The method proposed in this research utilizes the first order second moment theory and an analytical model based on the method of equivalent thickness. For the risk analysis of embankments the first order second moment method was also identified as suitable in the context. An integrated example of the proposed procedure is given, using the data from one of the roads tested. Existing quality control methods and techniques were also reviewed to develop a suitable quality control procedure for Bangladesh. For pavements, a performance based quality control procedure considering their load carrying capacity as an acceptance criterion was also suggested in this research, together with a quality control procedure for embankments.
