| Description: | Technical Report Abstract: This report summarizes an investigation into the cause of excessive sliver-spall damage in new airfield concrete after first winter exposure in Nebraska. The damage was particularly concentrated along joints that experienced more service loads than average; however, other sections of high-load joints showed no damage. The results showed that a combination of deficiencies in air entraining, sporadic occurrence of nondurable coarse aggregate and, possibly, early application of deicing salts contributed to the damage. The amount of new damage was notably lower after the second winter of exposure. Several recommended revisions to current concrete practice were made. |
