| 摘要： | MORTH issued two circulars for pavement option study. Default mode of pavement option is rigid pavement. Rigid pavement option has been considered based on least Green House Gas emission, least life cycle cost and highest benefit cost ratio. If flexible pavement option is considered, it shall be justified with consideration benefit cost ratio. Benefit cost ratio should be greater than one. A methodology of pavement option has been developed based on these two circulars of MORTH and presented in this paper for selection of pavement option. Two case studies have been carried for initial pavement cost variation within 20 % and more than 20%. Flexible and rigid pavement option considered initially for Case Study 1 and Case Study 2 respectively. Finally rigid pavement option has been found viable option based on life cycle and benefit cost ratio analyses for both cases. |
