Amashanyarazi ya asfalt yagenewe kubyara asfalt yamabuye kandi dufite module muri sisitemu ya software.Ikindi kandi dukora uruganda rukoresha selile. Hamwe nabakozi bacu b'inararibonye, ​​ntabwo dutanga kugurisha ibihingwa gusa, ahubwo tunatanga inkunga yo kugurisha nyuma yo kugurisha no guhugura abakozi.

SMA ni ntoya (12,5-40 mm) itandukanijwe-yuzuye, yegeranye cyane, HMA ikoreshwa nkamasomo yubuso haba mubwubatsi bushya no kuvugurura ubuso. Ni uruvange rwa sima ya asfalt, igiteranyo cyuzuye, umucanga wajanjaguwe, ninyongera. Izi mvange ziratandukanye nicyiciro gisanzwe cya HMA ivanze muburyo hari umubare munini cyane wa coarse agregate muri SMA ivanze. Irashobora gukoreshwa mumihanda minini ifite umuvuduko mwinshi wimodoka. Iki gicuruzwa gitanga imyambarire idashobora kwambara kandi ikarwanya ibikorwa byo gukuramo amapine. Iyi porogaramu kandi itanga gusaza gahoro kandi imikorere yubushyuhe buke.

SMA ikoreshwa mugutezimbere imikoranire no guhuza mubice bito byegeranye muri HMA. Asima ya sima hamwe nibice byiza byegeranye bitanga mastike ifata ibuye hafi. Igishushanyo mbonera gisanzwe kizaba gifite 6.0-7.0% sima yo mu rwego rwo hagati ya sima ya asifalt (cyangwa polymer yahinduwe na AC), 8-13% yuzuza, 70% byibuze byibuze birenze mm 2 (No 10), hamwe na fibre 0.3-1.5% na uburemere bwo kuvanga. Fibre isanzwe ikoreshwa muguhindura mastike kandi ibi bigabanya imiyoboro ya binder mukuvanga. Ubusanzwe ubusanzwe bubikwa hagati ya 3% na 4%. Ingano ntarengwa iri hagati ya 5 na 20 mm (0.2 kugeza 0.8 muri.).

Kuvanga, gutwara, no gushyira SMA koresha ibikoresho bisanzwe hamwe nibikorwa bitandukanye. Kurugero, ubushyuhe bwo kuvanga ubushyuhe bugera kuri 175 ° C (347 ° F) mubisanzwe birakenewe kubera igiteranyo cya coarser, inyongeramusaruro, hamwe na asfalt iri hejuru cyane ya asfalt ivanze na SMA. Nanone, iyo fibre ya selile ikoreshwa, igihe cyo kuvanga kigomba kongerwa kugirango yemererwe neza. Kuzunguruka bitangira ako kanya nyuma yo gushyirwaho kugirango bigere ku bucucike vuba mbere yo kuvanga ubushyuhe bugabanuka cyane. Ubusanzwe guhuza bikorwa hakoreshejwe toni 9-11 (toni 10-12) ibyuma bizunguruka. Kuzunguruka kunyeganyega birashobora kandi gukoreshwa ubwitonzi. Ugereranije na HMA isanzwe yuzuye, SMA ifite uburyo bwiza bwo guhangana nogosha, kurwanya abrasion, kumeneka, hamwe na skid irwanya, kandi bingana no kubyara urusaku. Imbonerahamwe 10.7 yerekana kugereranya amanota ya SMA yakoreshejwe muri Amerika n'Uburayi.
