Flexible Pavement Surface Condition Evaluation for the Routine Maintenance of Road: A Case Study on Pepsicola-ManoharPuranothimi Road Section, Nepal

Sunil Khyaju

Abstract


This is the survey study of different type of flexible pavement surface failure to determine the surface distress index for the determination of the right maintenance at right time that a road section should have. The road section feeder road F086 Pepsicola to old thimi is selected for the study as it is an alternative route to the Araniko highway that connects Bhaktpaur and Eastern Nepal to capital city, Kathmandu. The section is divided to three links viz; link 1: Pepsicola to Manohara bridge (0+000 to 0+480), link:2 0+541 to 1+200 and link 3: 1+200- 1+700.The study reveals that maximum surface failure of the pavement is wide cracking, narrow cracking, rutting patches and raveling. This study concluded surface distress index as 3, and the pavement condition is categorized as fair surface condition. The result indicates that the best pavement remedial action is resealing with local patches.
