ASSESSMENT OF CONCRETE PAVEMENT BLOWUPS

The assessment is based on the analyses of pavement blowups presented by the writer and his coworkers Dallis and Shade. The introduction rev iews briefly the various early attempts to clarify the blowup phenomen on. The next section describes the blowup mechanism, the adopted crite rion of the ''safe temperature increase,'' and an outline of the analy tical methodology this presentation is based on. The third section con tains the analytical solutions for three typical pavement problems, th e description of steps for their numerical evaluation as well as a lis t: of the used pavement parameters, and a graphical presentation of th e obtained results. The fourth and fifth sections contain a discussion of the practical implications of the presented results for concrete p avement design, as well as for assessing pavement blowups after years of service. Also presented are a number of specific pavement problems and suggestions of full-scale tests for the determination of the ident ified pavement parameters.
