Pavement Assessment of Farm Roads in Bhutan

A subjective assessment was carried out to study the present condition of farm road pavements in Bhutan. Three farm roads, each in Phuntsholing, Tsirang and Paro were selected for the study, taking into considerations the road environment parameters. A subjective approach of evaluation was adopted for the study. The total of a 12km stretch of farm roads was segmented into units of one kilometre and every distress parameter data was collected in an assessment form. The results were analysed to identify the conditioning factors for deterioration of the pavement of farm roads. The results obtained from three different farm roads were also compared to study the impact of pavement layer, climate, soil type and terrain on the performance of the pavement of farm roads. The constructional defect was identified as one of the main contributors for the failure of the pavement of farm roads. The degree of distresses were compared with some of the standard rating criteria and most of the distresses were found to contribute to the poor performance of the pavement. Accordingly, some areas of improvement were prioritized for immediate implementation for the construction of upcoming farm roads in the nation.
