Investigation and Analysis of International Roughness Index at National Freeway in Taiwan

Abstract:

Taiwan's National Freeway plays an important role in Taiwan's transportation, it is convenient to go to anywhere through a series of north-south and east-west road networks, from this we can see, the freeway road quality is a project that always need to be concerned, and how to enhance the pavement quality of National Freeway will be the main subject of this study.In order to improve the comfort index of National Freeway in this study, we first understand the examination part of National Freeway, like road testing items and methods, and because the need of study, we need to organize the relevant information of National Freeway road comfort index and investigation processes, with the investigation and analysis processes, it is beneficial to maintain and enhance the comfort quality of National Freeway.
