Simba asphalt zvinomera zvakagadzirirwa kugadzirwa kwematombo mastic asphalt uye isu tine module mune yedu software system.Also isu tinogadzira cellulose dosing unit.Nevashandi vedu vane ruzivo, isu hatipei chete kutengesa kwemiti, asiwo mushure mekutengesa kushanda kwekutsigira uye kudzidziswa kwevashandi.

SMA itete (12.5-40 mm) gap-graded, densely compacted, HMA iyo inoshandiswa senzira yepasi pazvose zviri zviviri kuvaka uye kuvandudzwa kwepasi. Musanganiswa weasphalt simende, coarse aggregate, jecha rakapwanyika, uye zvinowedzera. Aya masanganiswa akasiyana kubva kune akajairwa dense giredhi HMA musanganiswa mukuti kune yakakura kwazvo huwandu hwakakasharara musanganiswa weSMA. Inogona kushandiswa mumigwagwa mikuru ine mavhoriyamu anorema. Ichi chigadzirwa chinopa rut inodzivirira kupfeka kosi uye kuramba kune abrasive chiito chematairi akaiswa. Ichi chishandiso chinopawo kunonoka kuchembera uye yakanaka yakaderera-tembiricha kuita.

SMA inoshandiswa kukwidziridza kudyidzana uye kubata pakati peiyo coarse aggregate chikamu muHMA. Asphalt simende uye akakwenenzverwa aggregate zvikamu zvinopa iyo mastic inobata dombo padhuze. Typical mix dhizaini inowanzova ne6.0-7.0% yepakati-giredhi asphalt simende (kana polymer-modified AC), 8–13% filler, 70% yakaderera aggregate yakakura kupfuura 2 mm (No 10) seeve, uye 0.3–1.5% fiber uremu hwekusanganiswa. Fibers dzinowanzo shandiswa kudzikamisa mastic uye izvi zvinodzikisira kubuda kwebinder mumusanganiswa. Voids inowanzochengetwa pakati pe3% ne4%. Maximum particle sizes kubva pa5 kusvika ku20 mm (0.2 kusvika 0.8 in.).

Kusanganisa, kufambisa, uye kuiswa kweSMA shandisa midziyo yechinyakare uye maitiro ane zvimwe zvakasiyana. Semuyenzaniso, tembiricha yekusanganisa yakakwira ingangoita 175°C (347°F) inowanzodiwa nekuda kwekukasira kuunganidzwa, zvekuwedzera, uye yakakwira viscosity asphalt mumasanganiswa eSMA. Uyezve, kana cellulose fibers inoshandiswa, nguva yekusanganiswa inofanira kuwedzerwa kubvumira kusanganiswa kwakakodzera. Kutenderedza kunotanga nekukurumidza mushure mekuiswa kuti uwane density nekukurumidza kusati kwadzikira tembiricha yemusanganiswa. Kubatana kunowanzoitwa nekushandiswa kwe9-11 tonne (10-12 toni) mavhiri-mavhiri esimbi. Vibratory rolling inogonawo kushandiswa nekuchenjerera. Kuenzaniswa neyakajairika dense-graded HMA, SMA ine nani shear kuramba, abrasion kuramba, kupaza kuramba, uye skid kuramba, uye yakaenzana nekugadzira ruzha. Tafura 10.7 inomiririra kuenzanisa kwekugadzika kweSMA kunoshandiswa muUnited States neEurope.
