LONG-TERM HEALTH MONITORING OF PAVEMENT DEFORMATIONS ON AN EXPRESSWAY
Abstract
The increasing traffic density and increasing axle loads on highways requires an efficient road maintenance. Within a long-term project over 10 years load and pavement deformations on a heavily travelled expressway are measured. A newly developed sensor based on the magnetostrictive principle measures the vertical deformations within the pavement layers in parallel to existing inductive sensors. Short-term data of the two different systems and longterm data of the new sensor over a one year period are presented and further improvements discussed.
