Nubwoko bwa asphalt irwanya guhindura, bikwiranye mumihanda ifite traffic nyinshi. Byakoreshejwe mumishinga yikibuga cyindege mumyaka yashize. Ibuye rya Mastic Asfalt (SMA) ni imvange ishyushye ikubiyemo 70-80% Coarse Coarse, 20-30% argwate na 6-7% birumen. Yatejwe imbere mu Budage mu myaka ya za 1960 kandi yakurikijwe bwa mbere i Kiyeli, mu Budage.

Bitewe na coarse ya coarse iringaniye muvanga, icyuho kibaho hagati ya comgretret. Iyi myuga yuzuyemo minisiteri ya mastic (igiteranyo cyiza, cyuzuye, polymer yahinduye bitumen, fibre ya selile).

Imiterere yumusaruro
Bitumen hamwe nubumara burya bukwiye gushyuha kubushyuhe buke bwa 175 ° C (dogere) na ntarengwa 190 ° C (dogere).
Igihingwa: Bikwiye kugira ibikoresho byo guhita ugaburira fibre yongeraho hamwe nibikoresho byuzuza ku buremere bugenewe.
Imvange ishyushye itemba igomba kubikwa muri bunfalt ishyushye hamwe no gushyushya no kwigana.
Gufata imvange muri Bunfalt Ashyushye igomba kuba mugihe runaka.
Iyo imvange ishyushye yagejejwe kuri paver, ubushyuhe bwikirere bugomba kuba byibuze 10 ° C hamwe nubushyuhe buvanze bugomba kuba byibuze 170 ° C.
Bitewe numubare munini wa Coarse (usigaye kuri ecran ya kabiri) mu buryo buvanze, ubushobozi bwo gutwara ibintu biri hejuru ya spimet ya cumuminius asphalt.
Mubisanzwe, basalt cyangwa bisa na dilica ndende ya silica birakoreshwa, bityo kurwanya amakosa ni menshi.
Ubushakashatsi bwerekana ko SMA itsinze kuruta asfalt ya bituminious mubijyanye nuburyo bwo hejuru no kurwanya slip.
Kubera ko irimo bitumen cyane bitumen kuruta asfalt ya bitumini, birahanganira cyane ku nkombe yubushyuhe.
Mu buryo nk'ubwo, ifite uruhare runini kuri umunaniro.
Itanga igihuru kandi cyoroshye gutwara bitewe n'imiterere ya mastike.

Igice cya fibre cyongeweho gikoreshwa kumusaruro wamabuye asfalt
Ibimera bya Ashalts byashizweho kumabuye ya mastic asfalt kandi dufite modul ya sisitemu ya software.
