Ukutywinwa kwegrabile okudityanisiweyo kukusebenzisa izixhobo ezikhethekileyo, ezizezi iloli yokutywina yegrabile ehambelanayo kunye nezixhobo zokubopha (i-asphalt eguqulweyo okanye iasphalt eguqulweyo emulsified) ukuba isasazwe ngaxeshanye kumphezulu wendlela, ize yenziwe ibe ngumaleko omnye ngokuqengqeleka kwetrafikhi yendalo okanye ukuqengqeleka kwevili. . Umaleko we-asphalt gravel enxibe umaleko, osetyenziswa ikakhulu njengomaleko ongaphezulu wendlela, kwaye unokusetyenziselwa ulwakhiwo lomgangatho ongaphezulu koohola beendlela zomgangatho ophantsi.

Ukutywinwa kwegrabile okudityanisiweyo kugxininisa iinkqubo ezimbini zokutshiza i-binder kunye nokusasazeka kwegrabile kwisithuthi esinye, kuvumela amasuntswana egrabile ukuba adibane kwangoko nesibophelelo esandula kutshizwa. Ngeli xesha, ngenxa yokuba i-asphalt eshushu okanye i-emulsified asphalt ine-fluidity engcono, inokungcwatywa nzulu kwi-binder nangaliphi na ixesha. Itekhnoloji ye-synchronous gravel yokutywina inciphisa umgama phakathi kokutshiza kwe-binder kunye nokusabalalisa ngokudibeneyo, ukwandisa indawo yokugquma amasuntswana adibeneyo kunye ne-binder, yenza kube lula ukuqinisekisa ubudlelwane obuzinzileyo phakathi kwabo, kunye nokuphucula ukusebenza kakuhle. Inciphisa ukwakhiwa kwezixhobo kunye nokunciphisa iindleko zokwakha. Emva kokuba umgaqo we-asphalt uphathwa ngokutywinwa kwegrabile ngaxeshanye, i-pavement ineempawu ezibalaseleyo zokuchasana nokutyibilika kunye nokuchasana nokuphuma kwamanzi. Inokuzinyanga ngokufanelekileyo iingxaki zendlela ezinjengokuncipha kweoli, ukulahleka kweenkozo, iintanda, ukurutla nokuthotywa. Isetyenziswa ikakhulu kwiindlela. ulondolozo lothintelo nolulungisayo
Umatshini wokutywinwa we-synchronous gravel sisixhobo esikhethekileyo esivumelanisa ukutshiza kwe-asphalt binder kunye nokusabalalisa kwamatye, ukwenzela ukuba kubekho ukudibanisa okwaneleyo kwendawo phakathi kwe-asphalt binder kunye ne-aggregate ukufezekisa ubuninzi bokubambelela phakathi kwabo.
