Blowup of a Concrete Pavement Adjoining a Rigid Structure
The main cause of concrete pavement blowups are axial compression forces induced into the pavement by a rise in temperature and moisture. Recent analyses by the writer and his students were based on the notion that blowups are caused by lift-off buckling of the pavement. The cases analyzed were: (1) continuously reinforced concrete pavement and (2) concrete pavement weakened by a traverse joint or crack. The present paper contains an analysis of another case, when a long continuously reinforced concrete pavement adjoins a rigid structure, like a bridge abutment. The analysis is similar to the ones described above. The resulting formulation is non-linear and is solved exactly, in closed form. The obtained results are evaluated numerically and are compared with those of a long continuously reinforced pavement, in order to show the effect of the rigid structure on the pavement response.
