HMA Performance Tests – Pavement Interactive

Performance tests are used to relate laboratory mix design to actual field performance. The Hveem (stabilometer) and Marshall (stability and flow) mix design methods use only one or two basic performance tests. Superpave is intended to use a better and more fundamental performance test. However, performance testing is the one area of Superpave yet to be implemented.

Portland Cement Tensile Strength – Pavement Interactive

Although PCC is not nearly as strong in tension as it is in compression, PCC tensile strength is important in pavement applications. Tensile strength is typically used as a PCC performance measure for pavements because it best simulates tensile stresses at the bottom of the PCC surface course as it is subjected to loading. These stresses are typically the controlling structural design stresses.

Design of Concrete Pavement for City Streets

Under repeated axle loads concrete pavements bend, producing both compressive and flexural stresses. Since the ratio of compressive stress to compressive strength is relatively small compared to the ratio of flexural stress to flexural strength, the flexural strength of concrete is the controlling factor in pavement design. The flexurai
