Abstract:
In highway research of the last few years nothing has been more clearly demonstrated than the instability and non-uniformity of the pavement subgrade. For this reason the pavement must be designed as a floor slab rather than a wearing surface. Therefore, practically all of the formulas developed for highway design in the last few years use the transverse strength as a factor rather than the compressive strength. However, as this change in design has been comparatively recent, tests of materials used in pavements, as well as the data compiled concerning these materials, and the finished concrete, have dealt with the compression test. There has been considerable discussion, with little knowledge gained, as to the measure in which the ultimate compressive stress indicates the transverse strength of the concrete.
