Strength Gain and Cementation of Flexible Pavement Bases (Revised)
The report deals with the strength gain of selected carbonate FDOT flexible pavement base materials. The gain in strength after aging of base sections constructed in an Inside environment and Outside environment was measured. Scanning Electron Microscope photos were also taken and examined to determine changes in structure. The materials investigated were: (1) Bank Run Shell, (2) Limerock, (3) Cemented Coquina. Strength tests were the Clegg Impact Value (CIV) performed on Inside and Outside Sections; and a Rigid Plate Test performed on the Inside Section. There was a small gain in strength for all three carbonate bases after 22 months. Changes in the matrix particles were observed in the SEM Study. The three complementary phases (CIV, Plate Modulus, and SEM) tend to reinforce each other, indicating a small gain in strength.
