| dc.description.abstract | Pavement roughness reacts on profile which clearly describes the roughness; the pavement roughness is one of the important indicators for the passengers in public, for this reason, we suggestion the transportation institute of the government to pay attention to the pavement roughness. The IRI (International Roughness Index, IRI) is the most broadly used index. However, no matter what index is calculated from a longitudinal profile, the quality of the information is only as good as the profile measurement.
Monitoring pavement roughness with profile measurements involves several interdependent variables that fall into five categories: the equipment design, the pavement shape, the measurement environment, the manner in which the equipment is operated, and the driver and operator proficiency. Current standards appear to address the equipment design, but not the other variables. As a result, these standards need to be reconsidered.
Comparing to the other country, the correlative certification organizations in land establish the standards and a set of verification process, not yet. This article definitely considers some important standers, for instance AASHTO (Association of State Highway and Transportation Officials, AASHTO) and ASTM (American Society for Testing and Materials Standards, ASTM). This study proposal builds a procedure for profiler. | en_US |
