PCC - TESTING
The challenge in PCC testing is to develop physical tests that can satisfactorily characterize key PCC performance parameters and the nature of their change throughout the life of a pavement. These key parameters are:
· Workability. This parameter, typically measured by slump, is indicative of fresh concrete rheology.
. Strength : This parameter is related to a rigid pavement's ability to support loads. Flexural Strength is commonly used in design and then correlated to Compressive Strength for use in field tests.
· Durability : Several tests can be conducted to determine susceptibility to freeze-thaw or Chemical attack damage.
· Early Age Behavior: HIPERPAV, a software program, can be used to predict early-age PCC behavior.
