Abstract:

The safety of civilians is of paramount importance during the construction and repair of concrete pavements. A complete understanding of the pavement distresses that compromise the structural stability and performance of rigid pavements are required for a proper selection of the repair method. Additionally, the time required to complete the repair process should be minimized to reduce the delay imposed on the users of the transportation facilities. The US Air Force Research Laboratory (AFRL) in association with the Air Force Civil Engineering Support Agency (AFCESA) developed a state of practice protocol for the repair of damaged runways using precast concrete slabs. The current study tends to extrapolate the previous research on this topic to civilian highway pavements. In the AFRL study, three installation techniques, widely used by the transportation industry, were incorporated in the experiment design. The original study did not consider the influence of temperature fluctuations, humidity and the stresses induced by environmental conditions for the performance evaluation of the precast slabs. This study tends to capture the influence of the climatic conditions on the orthogonal load bearing capacity of repaired sections.
