文摘
- •
Preparation of binary and ternary bituminous composites with MDI and Cloisite 20A®
- •
C20A® clay addition improves thermo-mechanical stability of the resulting composite.
- •
MDI addition and low shear stirring structurally destabilize the composites.
- •
Preferential reactivity of MDI with reactive groups in C20A over those in bitumen
- •
The order of addition of C20A and MDI radically changes the LVE response.
