## The treated layer shall be cured to retain moisture for the reaction, and the curing method shall be selected for the treatment type and climate.
−### Cement-stabilized layers lose surface strength and crack if they dry before the reaction completes; a curing membrane or continuous moist curing protects the surface until an overlying course is placed. {note}
