Izityalo ze-asphalt zamandla zenzelwe ukuveliswa kwe-asphalt yamatye kwaye sinemodyuli kwinkqubo yethu yesofthiwe.Kwakhona sivelisa i-cellulose dosing unit.Ngabasebenzi bethu abanamava, asinikezeli kuphela ukuthengiswa kwezityalo, kodwa kunye nenkxaso yokusebenza emva kokuthengisa kunye nokuqeqeshwa kwabasebenzi.

I-SMA ibhityile ngokwentelekiso (12.5–40 mm) igap-graded, ixinene, i-HMA esetyenziswa njengekhosi engaphezulu kulwakhiwo olutsha kunye nokuhlaziya umphezulu. Ngumxube wesamente ye-asphalt, i-aggregate erhabaxa, isanti etyumkileyo, kunye nezongezo. Le mixube yahlukile kwimixube yeHMA eshinyeneyo yesiqhelo kuba kukho umyinge omkhulu weaggregate erhabaxa kumxube we-SMA. Ingasetyenziswa koohola beendlela ezinkulu ezinemithamo enzima yezithuthi. Le mveliso ibonelela ngekhosi yokunxiba enganyangekiyo kunye nokuchasana nesenzo esirhabaxa samatayara. Esi sicelo sikwabonelela ngokuguga kancinci kunye nokusebenza okuhle okuphantsi kobushushu.

I-SMA isetyenziselwa ukukhulisa intsebenziswano kunye noqhagamshelwano phakathi kweqhezu elirhabaxa le-HMA. I-asphalt yesamente kunye neenxalenye ezidibeneyo zibonelela nge-mastic ebambe ilitye ngokusondeleyo. Uyilo lomxube oluqhelekileyo luya kuba ne-6.0-7.0% ye-asphalt ye-medium-grade sement (okanye i-polymer-modified AC), i-8-13% yokuzalisa, i-70% ubuncinci be-aggregate enkulu kune-2 mm (No 10) isisefo, kunye ne-0.3-1.5% ye-fibers nge- ubunzima bomxube. Iintsinga zisetyenziswa ngokubanzi ukuzinzisa imastic kwaye oku kunciphisa umjelo wokukhupha isibophelelo kumxube. I-Voids idla ngokugcinwa phakathi kwe-3% kunye ne-4%. Ubuninzi bemilinganiselo yamasuntswana ukusuka kwi-5 ukuya kwi-20 mm (0.2 ukuya kwi-0.8 in.).

Ukuxuba, ukuthuthwa, kunye nokubekwa kwe-SMA kusebenzisa izixhobo eziqhelekileyo kunye nezenzo ezinokwahluka okuthile. Umzekelo, ubushushu bokuxuba obuphezulu obumalunga ne-175 ° C (347 ° F) buhlala buyimfuneko ngenxa ye-aggregate erhabaxa, izongezo, kunye ne-asphalt ephezulu ye-viscosity kwimixube ye-SMA. Kwakhona, xa kusetyenziswa imicu ye-cellulose, ixesha lokuxuba kufuneka linyuswe ukuvumela ukuxuba okufanelekileyo. Ukuqengqeleka kuqala kwangoko emva kokubekwa ukufezekisa ukuxinana ngokukhawuleza phambi kokuba ubushushu bomxube bunciphe kakhulu. I-Compaction idla ngokufezekiswa ngokusetyenziswa kwe-9-11 tonne (10-12 tonne) iirola ezinamavili entsimbi. I-Vibratory rolling nayo ingasetyenziswa ngononophelo. Xa kuthelekiswa ne-HMA eshinyeneyo eqhelekileyo, i-SMA inokumelana nokucheba okungcono, ukuxhathisa kwe-abrasion, ukumelana nokuqhekeka, kunye nokumelana nokutyibilika, kwaye ilingana nokwenza ingxolo. Itheyibhile 10.7 imele ukuthelekiswa kokuhlelwa kwe-SMA esetyenziswa eUnited States naseYurophu.
