Higher curing temperatures significantly reduce the allowable construction time, indicating the need for precise control during the setting process.
The viscosity of TPUA binders is most influenced by hard segment content, PU dosage, and curing temperature, impacting performance in pavement systems.
A viscosity-temperature evolution model effectively simulates initial viscosity changes, providing a tool for predicting behavior during application.
Understanding these key factors is crucial for optimizing TPUA formulations, improving workability and overall pavement quality.
