Traffic Performance Valuation of NH-1

ABSTRACT:  The country has witnessed tremendous rise in the Traffic Performance Valuation of NH-1. The type of decline current in the pavement should be considered for determining whether it has a functional or structural deficiency, so that correct overlay type and design can be developed. Structural failure rises from the conditions that adversely affect the load carrying capability of the pavement structure. Inadequate thickness, cracking, distortion and disintegration cause structural deficiency. Functional deficiency rises when the pavement does not provide a smooth riding surface and comfort to the user. This can be due to deprived surface friction and texture, hydro planning and splash from wheel path, rutting and excess surface distortion such as potholes, corrugation, faulting, blow up, settlement, heaves etc. Functional condition determines the level of service provided by the facility to its users at a particular time and also the Vehicle Operating Costs (VOC), thus influencing the national economy. Forecast of the pavement deterioration is helpful to assess the remaining effective service life (RSL) of the pavement structure on the basis of reduction in performance levels, and apply many alternative designs and rehabilitation strategies with a long range funding requirement for pavement preservation. In addition, they can forecast the impact of treatment on the condition of the sections. The infrastructure forecast models can thus be classified into four groups, namely primary response models, structural performance models, functional performance models and damage models.
