Emulsion bitumen ni emuliyoni nshya ikorwa nigikorwa cyumukanishi wa asfalt na emulifier amazi yumuti.
Emulsion bitumen ishyirwa mubikorwa ukurikije ibice bitandukanye bigize emulifier ya bitumen ikoreshwa: bitumen cationic emulsion bitumen, anionic emulsion bitumen na bitumen nonionic emulsion bitumen.
Kurenga 95% byubwubatsi bwumuhanda bukoresha cationic emulsion bitumen. Kuki bitumen ya cationic emulsion ifite ibyiza nkibi?
1. Guhitamo amazi ni mugari. Bitumen, amazi na emumifier ya bitumen nibikoresho byingenzi bya emulion bitumen. Anionic emulised bitumen igomba gutegurwa namazi yoroshye kandi ntishobora kuvangwa namazi akomeye. Kuri cationic emulsion bitumen, urashobora guhitamo emulion bitumen kumazi akomeye. Urashobora gukoresha amazi akomeye kugirango utegure igisubizo cyamazi ya emulifier, cyangwa urashobora kuyungurura.
2. Umusaruro woroheje kandi uhamye. Ihungabana rya anion irakennye kandi ibivanze bigomba kongerwaho kugirango ibicuruzwa birangire. Mubihe byinshi, bitumen ya cationic emulion irashobora kubyara biti bihamye bitiriwe byongera izindi nyongeramusaruro.
3. Kuri cationic emulsion bitumen, hariho inzira nyinshi zo guhindura umuvuduko wa demulisation kandi igiciro ni gito.
4. Asifalt ya emulisifike irashobora kwubakwa nkuko bisanzwe mugihe cyizuba cyangwa ubushyuhe buke (hejuru ya 5 ℃).
5. Gufata neza ibuye. Cumic emulsion bitumen ibice bitwara amafaranga ya cationic. Iyo uhuye namabuye, ibice bya asfalt byihuta byerekanwa hejuru yibuye kubera gukurura ibintu bitandukanye. Ikoreshwa muri micro surfacing hamwe no kubaka kashe ya kashe.
6. Ubukonje bwa cationic emulsion bitumen nibyiza kuruta ibya anionic emulsion bitumen. Iyo gushushanya, bitumen ya cationic emulsion iragoye cyane, urashobora rero guhitamo kuyitera. Ibinyuranye, anionic emulsion bitumen iroroshye gusiga irangi. Irashobora gukoreshwa nk'amavuta yinjira mu mavuta hamwe n'amavuta yo mu rwego rwo kubaka amazi no gutunganya umuhanda.
7. Cumic emulsion bitumen ifungura traffic byihuse.
