Thephula lopangidwa ndi polimaali ndi ubwino wa khalidwe lodalirika, kachitidwe kokhazikika, muyeso wolondola ndi ntchito yabwino, ndipo ndi zipangizo zatsopano zofunika kwambiri pomanga misewu yayikulu.

Masiku ano, ukadaulo wosinthidwa wa phula wopangidwa ndi polima umagwiritsidwa ntchito ndi ofufuza komanso  opanga mu emulsion ya phula kuti apititse patsogolo magwiridwe antchito a emulsion ya phula. Mitundu yosiyanasiyana ya ma polima angagwiritsidwe ntchito pokonza polima modified asphalt emulsion monga styrene butadiene styrene (SBS) block copolymer, ethylene vinyl acetate (EVA), polyvinyl acetate (PVA), styrene butadiene rabara (SBR) latex, epoxy resin ndi raba zachilengedwe. latex. Polima akhoza kuwonjezedwa mu  asphalt emulsion m'njira zitatu: 1)  njira yosakaniza kale, 2) njira yosakaniza nthawi imodzi ndi 3) njira yosakaniza. Njira yophatikizira ili ndi chikoka pakukula kwa netiweki ya polima ndipo ikhudza magwiridwe antchito a ma emulsion a phula a polima. Kusakhalapo kwa protocol yogwirizana kwalola kuti njira zosiyanasiyana zigwiritsidwe ntchito poyesa ma laboratories kuti apeze zotsalira za asphalt emulsion. Pepalali likuwonetsa mwachidule zofufuza zomwe zachitika pa ma emulsion a phula osinthidwa a polima pogwiritsa ntchito mitundu yosiyanasiyana ya ma polima ndi momwe amagwiritsira ntchito.

Sinoroaderphula lopangidwa ndi polimaangagwiritsidwe ntchito kusintha phula, yomwe imakhala ndi colloid mphero, modifier feeding system, thanki yomalizidwa, thanki yotenthetsera phula, makina owongolera makompyuta ndi chipangizo choyezera pakompyuta. Ntchito yonse yopanga imayang'aniridwa ndi pulogalamu yamakompyuta.
