• Abstract:
  The effectiveness of load transfer between adjacent slabs is an important component of long term rigid pavement performance. When load transfer is minimal or non-existent, concrete slabs must carry the full weight of truck axles across their entire length. This condition results in high dynamic tensile stresses being induced in the slab and high dynamic compressive stresses being generated in the base and subgrade. The purpose of this project was to instrument and install a total of 12 dowel bars in an in-service pavement and monitor their response under environmental cycling and dynamic loading. An examination of this data might provide some insight into the reasons for this premature distress.
