Research Objective: The first two phases of research on heat evolution have provided necessary preliminary results for potential applications of field calorimetry. Phase 3 will focus on field verification and implementation.

Currently, the HIPERPAV program uses predicted heat evolution based on cement charactertistics and concrete mix design. This information is a fundamental input to HIPERPAV for the prediction of the pavement concrete set time, strength, and stress development during the early age. Instead of using the existing HIPERPAV database, this project will use the calorimeter test results as input data for the HIPERPAV program analysis, thus improving its reliability.

The results from the HIPERPAV analysis can be used for concrete quality control, optimization of pavement designs, and prediction of pavement performance. They can also help contractors manage the temperature of concrete based on the concrete mix designs and specific climate and project conditions.
