摘要: |
The integration of the profilograph into BELMAN, the pavement management system used on the Danish state road network, is investigated. In this case, the "profilograph" is a condition measurement device based on laser technology, and it must not be confused with the U.S. "profilograph". Also investigated are the establishment of suitable procedures for data handling and analysis and the performance models needed to integrate the profilograph data into the BELMAN system. Denmark began to develop a systematic approach to pavement management in the 1970s and has since developed a fully operational pavement management system that evaluates pavement management strategies for the entire Danish state road network based on performance models (i.e., the BELMAN system). The most recent enhancement to the BELMAN system is its integration with the Danish profilograph. By incorporating the exact measurements of roughness and profile data obtained through the profilograph, the BELMAN system's capabilities for planning maintenance and rehabilitation strategies have been greatly improved. The profilograph records very precise data on the geometry of the pavement surface obtained by 17 laser sensors mounted on a moveable bar, as well as gyroscopes and accelerometers. The geometrical data are processed afterward to produce longitudinal roughness (e.g., IRI), cross fall, rutting, and curvature. Integration of the profilograph's measuring system into the Danish pavement management system also involved development of suitable procedures for handling and analyzing the tremendous amount of data and information that the profilograph provides about the road network. New models for performance prediction using the profilograph data were also developed. |
