Study on the Influence Factors of the Dynamic Property of the Polyurethane Mixture with Dense Gradation

Similar to the asphalt mixture, polyurethane (PU) mixture’s performance and characteristics are dependent on many variables. In this study, six variables, including aggregate gradation (limestone basalt), type, PU content, curing condition, several parameter analyzing methods were chosen determine effect of variables dynamic property, rheological rutting resistance mixture. The limestone exhibited a substantial mixture; basalt significant influence property resistance, but moderate property. type could resistance. slow speed binder decreased modulus did not phase angle. rise in content would only improve rutting. condition color additive had no impact properties. generalized logistic sigmoidal (GLS) Christensen Anderson Marasteanu model (CAM) models precisely predict angle respectively disregarding mixture features.
