Igihe nikigera kugirango rwiyemezamirimo afate icyemezo cyo kugura uruganda rwa asfalt, arashobora kubirekera kubatanga kugirango bafashe guhitamo imiterere nuburyo bwiza. Nkumuyobozi wikoranabuhanga wibiti bivangwa na asfalt, turashobora guha abakiriya bacu ibisubizo byimashini zigendanwa zo kubaka umuhanda no gusana umuhanda, no kubyara asfalt.

Mubice bivanga ibihingwa bya asfalt uburemere bwa agregate bugenzurwa nyuma yo gukama, mbere yuko bigaburirwa kuvanga. Gupima rero, mubyuma bipima ntibiterwa nubushuhe cyangwa nibintu bitandukanye, nkikirere gihindagurika.

Mu bimera bya asfalt, kuvanga n'amaboko abiri na padi bisobanura ko kuvanga ubuziranenge ari byiza iyo ugereranije nibihingwa bikomeza kuko bihatirwa. Iyi mikorere ni ingenzi cyane mugihe ikorana n '' ibicuruzwa bidasanzwe '(porous asfalt, splittmastik, ibirimo RAP yo hejuru, nibindi), bisaba urwego rwo hejuru rwo kugenzura ubuziranenge. Byongeye kandi, hamwe nuburyo bwo 'kuvanga ku gahato', igihe cyo kuvanga kirashobora kuramba cyangwa kugabanywa bityo ubwiza bwo kuvanga bushobora gutandukana, bitewe nubwoko bwibikoresho bikozwe. Kurundi ruhande, mubihingwa bikomeza uburebure bwibikorwa bivanga bigomba byanze bikunze guhoraho.

Sinoroader icyiciro cya asfalt kivanga ibimera bidahwema kuvanga ibice byapimwe neza (minerval, bitumen, uwuzuza) bivanze na asfalt mubice nkuko bivugwa muri resept ya mixe ya asfalt. Iyi nzira iroroshye guhinduka kuko resept ivanze irashobora guhinduka kuri buri cyiciro. Mubyongeyeho, ubuziranenge bwo kuvanga burashobora kugerwaho bitewe nubunini bwongeweho neza hamwe nigihe cyo kuvanga ibihe cyangwa kuvanga inzinguzingo.

Asfalt ishyushye igomba kugira ubushyuhe bwo gutunganya byibuze 60 ° C. Kubera ko imvange ya asfaltike itagomba gukonja munzira iva mu gihingwa cya asfalt igana iyo igana, birasabwa urunigi rwogutwara ibintu hamwe n’ibinyabiziga byihariye. Gukoresha ibinyabiziga bidasanzwe-bigamije bigira ingaruka ko asfalt ishyushye akenshi mubukungu bidashoboka kandi ntibishoboka gusanwa bito.

hamwe na tekinoroji ya Sinoroader, buri mukiriya arashobora kubona igisubizo kiboneye aho giherereye, ukurikije ibisabwa byihariye.
