The Michaelis-Menten model effectively describes the curing phenomenon of cold-recycled mixes
- el">•
Increasing cement dosage from 1% to 2.5% results in a long-term increase of strength/stiffness up to 1.5/2 times
- el">•
Increasing curing temperature from 25 °C to 40 °C results in an increase of the initial curing rate up to 2.5/3 times
- el">•
Strength/stiffness evolution was related to emulsion/cement curing, respectively
