Causes, Measurement and Prevention of Pavement Forces Leading to Blowups
A survey of blowup activity in Ohio's concrete pavements was conducted. One hundred and seventy-two blowups of various severity were reported during 1975 and 1976. A survey of blowup literature in the United States was conducted and resulted in an extensive bibliography of material dealing with jointed concrete pavements. A method of measuring residual strains within a concrete pavement was developed. Strain gage rosettes are attached to the walls of a corehole by means of an installation tool which was invented for this project. The hole is overcored and the relief strains are measured. Available theory has been adapted to allow computation of state of stress in the original slab at the level of the gages. Laboratory and field tests were conducted. Computer models of the overcore and an entire pavement slab were developed using the STRUDL package. Various temperature loadings and boundary conditions were studied.
