A reactant composition for forming a polymer via metal-free ring-opening metathesis polymerization may comprise a stabilizer, a stabilizing reactant comprising a stabilizing moiety covalently bound to a reactant moiety, or both; wherein the stabilizer is a halogenated alcohol and the stabilizing moiety is derived from a halogenated alcohol. The reactant composition further comprises a strained cyclic unsaturated monomer; an initiator; a mediator; and optionally, one or more of a co-monomer, a crosslinker, and a chain transfer agent.

Pavement aging can be reduced by applying to an asphalt-containing pavement a topcoat layer or a surface treatment containing asphalt binder with sterols.
