Tillståndsuppföljning av observationssträckor: datainsamling, lägesrapport 2010-12


The objective of this project is to collect and deliver high quality road data primarily for the development of performance prediction models. The monitoring of the LTPP sections started in 1984 on commission of the Swedish Road Administration. The aim is primarily to focus on road deterioration caused by heavy traffic. The project started with a limited amount of sections but the number, both active and inactive, has increased to 665 sections distributed over 67 sites. Budget restrictions in 2000 resulted in a decrease in monitoring by 25%. In 2010 there were still 328 active LTPP sections distributed over 35 sites. Road data from this project has been used in the development of flexible pavement models for predicting the cumulative number of load applications to the initiation of cracking and for predicting crack propagation. Crack initiation was defined as the first appearance of cracking in the wheel paths. The models were created using the same approach applied to the development of crack models used in the PARIS (Performance Analysis of Road Infrastructure) project carried out within the 4th European Framework Programme Road Transport 1996-1998.



Cost Benefit Analysis (CBA) workshop in Stockholm
