A platform for research: civil engineering, architecture and urbanism
Concerns over roadways exhibiting distress at ages earlier than expected led the Federal Highway Administration to initiate a study to examine pavements in the Mid west. The goal was to reach an early consensus as to the mechanism of the distress, and recommend corrective actions to prevent future occurances until additional needed research could be conducted. This report's recommendations must be taken within the context discussed in the text. Specific recommendations include advice on returning to the basic methods of concrete construction, and avoiding the use of known materials that contribute to early distress. Concrete components discussed include portland cement, fly ash, and aggregates. Also discussed are mixing and placing procedures that may detrimentally affect the strength and durability qualities of concrete through poor uniformity, workability, and air entrainment.
