Ibimera bya Ashalts byashizweho kumabuye ya mastic asfalt kandi dufite modul ya sisitemu ya software.
SMA NUBUNTU BUSOBANUWE (12.5-40 MM-PAP-PAP-PAP-PAPS-PAPS-YIFATANYIJE CYANE, HMA ikoreshwa nkubuso bwamasomo mashya no kuvugurura hejuru. Ni uruvange rwa sima ya Asfalt, abaterankunga rwose, bajanjaguwe, hamwe nabashyingo. Izivanga ziratandukanye nicyiciro kinini cya HMA HIVES kuko hari umubare munini cyane wo guhuza muri sma. Irashobora gukoreshwa mumihanda minini ifite umubumbe wimodoka nyinshi. Iki gicuruzwa gitanga akazu karwanirwa no kurwanya ibikorwa bya absas byize. Iyi porogaramu kandi itanga gusaza gahoro kandi nziza-yubushyuhe.
SMA ikoreshwa mugukoresha imikoranire no guhura hagati yigice kibujijwe muri HMA. Ingwate ya Asfalt na Francer Pernions ikubiyemo mastike ifata ibuye guhura cyane. Igishushanyo gisanzwe kizaba gifite imyaka 6.0-7.0% ya ASPHALT-REVECHT (cyangwa ihinduranya AC), 8-13% byibuze, na 0.3-1.5% by'uburemere bwo kuvanga. Fibre isanzwe ikoreshwa muguhungabanya mastike kandi ibi bigabanya imiyoboro ya binder muri kuvanga. Vode mubisanzwe ibikwa hagati ya 3% na 4%. Ingano ntarengwa yubunini kuva kuri 5 kugeza kuri mm (0.2 kuri 0.8 muri.).
Kuvanga, ubwikorezi, no gushyira sma Koresha ibikoresho nibikoresho bisanzwe hamwe nibihinduka bimwe. Kurugero, ubushyuhe bwo kuva hejuru bwa 175 ° C (347 ° F) mubisanzwe birakenewe kuberako coarser Comgfter, inyongera, hamwe nubwitonzi bukabije asphalt muri SMA. Kandi, iyo fibre ya selile ikoreshwa, igihe cyo kuvanga kigomba kwiyongera kugirango twemere kuvanga neza. Kuzunguruka bitangira ako kanya nyuma yo gushyira ubucucike vuba mbere yuko kuvanga ubushyuhe bigabanuka cyane. Guhura nibisanzwe bigerwaho no gukoresha 9-11 tonne (10-12 ton) ibyuma-ibiziga. Kuzunguruka vibratory birashobora kandi gukoreshwa witonze. Ugereranije na HMA isanzwe ya SMA, SMA ifite imbaraga zo guhangana n'amajwi, ibyuma bya atusion, guturwanya kurwanya, no kurwanya skid, kandi bingana ku rusako. Imbonerahamwe 10.7 Yerekana kugereranya amanota ya SMA yakoreshejwe muri Amerika n'Uburayi.
