Experienced durability of maintenance treatments

EPAM 2012: Malmö, Sweden, 5-7 September: 4th European Pavement and Asset Management Conference

The durability of a maintenance treatment depends on the conditions when the treatment was applied, such as road condition, traffic and environmental factors. For example, surface treatment carried out on a road with structural defects will have a shorter durability. Durability also differs between different countries due to differences in maintenance standards and strategies. The experienced durability is based on facts but has the disadvantage that considered treatments are based on older technology. In the same time, typically, it is not known if the pavement condition was similar when the treatments were applied, and there are usually changes in traffic over time. In Sweden, all pavement treatments longer than 100 m are required to be reported. In analysis of experienced durability app. 300 000 projects have been analyzed. The reported pavement treatment database covers a long period and contains historical information (several treatments at the same section). The durability of treatments is calculated as the age of a treatment when a new treatment is carried out. This means that the durability is valid for treatments that were carried out back in time. Another method discussed in the paper is time-to-event studies. This paper will show results of analyses and discuss problems in establishing expected durability.
