Abstract:
Quality control for airfield paving can be better maintained by means of compressive strength testing rather than be flexural strength testing. The relationship of flexural strength versus compressive strength, for a given set of materials, should be established by correlation tests. Laboratory correlation testings can be used for selecting initial mix proportions which produced the required flexural strength for starting the work. However, additional correlation tests should be made during initial paving to confirm, or more accurately, establish the relationship of compressive strength to flexural strength under actual construction conditions. The quality control program should also include the repeating of correlation tests at reasonable intervals. Technical specifications should be detailed on procedures required for establishing the initial paving mix and for adjustments during construction.
