Field studies of highway bridge performance have led to repeated observations of severe cracking and dislocation of the backwalls of reinforced-concrete abutments. The observed distress is correlated with the presence of adjacent reinforced-concrete pavements, and the cause is attributed to the longitudinal growth of the concrete pavements. Field observations are presented and discussed. A finite element model of a representative abutment is used to study the expected stress distributions caused by several hypothesized mechanisms that might contribute to the observed damage. Methods to prevent future damage are discussed.
