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

A magnesium phosphate bone cement includes a powder agent and a liquid agent. A liquid-to-solid ratio of the liquid agent to the powder agent is 0.1-0.5 ml/g. The powder agent comprises following components: phosphate accounting for 32-70 wt %, magnesium oxide accounting for 28-65 wt %, and silicon-containing compound accounting for 1-15 wt %. Preferably, the powder agent further comprises ammonium dihydrogen phosphate, and degradable and adhesion-promoting material, wherein the ammonium dihydrogen phosphate accounts for 5-30 wt % of a total weight of the phosphate.

A nonvolatile cold modified asphalt binder and a nonvolatile cold recycled asphalt mixture using the same are manufactured by optimally mixing a petroleum asphalt, a native asphalt, a polymer modifier, process oil, and an adhesive strength enhancer. The nonvolatile cold modified asphalt binder includes at least one petroleum asphalt selected from a straight asphalt or a blown asphalt; at least one native asphalt selected from gilsonite, glance pitch, and grahamite; a rubber-modified-compound (RMC) polymer modifier which is a vinyl aromatic hydrocarbon-conjugated diene block copolymer including at least one of a styrene-butadiene block copolymer (SBS), a styrene-isoprene block copolymer (SIS), and a styrene-ethylene-butylene block copolymer (SEBS); at least one process oil selected from paraffin oil, naphthenic oil, aromatic oil, natural oil, and mineral oil; and at least one adhesive strength enhancer selected from rosin esters, modified acryls, modified silicones, polyvinyl esters, and silicone resins.
