Asifalti yahinduwe ni ukongeramo ibivanze hanze (modifiers) nka reberi, resin, polymers nyinshi ya molekile, ifu ya reberi nziza cyane cyangwa izindi zuzuza, cyangwa gufata ingamba nko gutunganya okiside yoroheje ya asfalt kugirango ikore ivangwa rya asfalt cyangwa asfalt Imikorere ya guhuza asifalt birashobora kunozwa.
Hariho uburyo bubiri bwo guhindura asfalt. Imwe ni uguhindura imiti ya asfalt, indi nugukora modifier ikwirakwizwa muri asfalt kugirango habeho urwego runaka rwimiterere.
Rubber na thermoplastique elastomer yahinduwe asfalt
Harimo: reberi karemano yahinduwe asfalt, SBS yahinduye asfalt (ikoreshwa cyane), styrene-butadiene rubber yahinduwe asifalt, chloroprene reberi yahinduwe asifalt, butyl rubber yahinduye asfalt, butyl rubber yahinduye asfalt, reberi yimyanda no kuvugurura Rubber yahinduye asfalt, izindi rubber zahinduwe asfalt (nka etilene propylene reberi, reberi ya nitrile, nibindi.).
Harimo: polyethylene yahinduwe asifalt, Ethylene-vinyl acetate polymer yahinduwe asifalt, polystirene yahinduwe asifalt, coumarin resin yahinduwe asfalt, epoxy resin yahinduwe asifalt, α-olefin random polymer ihindura asfalt.
Polimeri ivanze yahinduwe asfalt
Polimeri ebyiri cyangwa nyinshi zongewe kuri asfalt icyarimwe kugirango uhindure asfalt. Polimeri ebyiri cyangwa nyinshi zavuzwe hano zirashobora kuba polimeri ebyiri zitandukanye, cyangwa zirashobora kwitwa polymer alloy zahujwe mbere kugirango zikore umuyoboro wa polymer.
