Hariho imiyoboro ibiri nyamukuru yo guhindura imiyoboro ya bitumen: uburyo bwo kuvanga hanze hamwe nuburyo bwo kuvanga imbere. Uburyo bwo kuvanga hanze ni ukubanza gukora igihingwa gisanzwe cya bitumen, hanyuma ongeraho polymer asobanura ibikoresho bisanzwe bya shanx bibangamiye ibikoresho bya bitumen, hanyuma uvange kandi ukane kugirango witegure. Amayoko ya polymer asanzwe asenyutse, embrions, na emuliclions. Uburyo bwo kuvanga imbere ni ukubanza kuvanga reberi, plastiki nibindi polymers nibindi bikubiye mubyo bishyushye kandi bikonje-bitumen amabara ya bitumen. Nyuma yo kuvanga no kuringaniza, no kwerekana uruhare ugereranije hagati ya polymer nubukonje-kuvanga amabara ya bitumen, bitumen-yahinduwe bitumen. , hanyuma nyuma yatumen emulsion yahinduwe binyuze muburyo bwa eduelssific. Polymer isanzwe ikoreshwa muburyo bwo kuvanga imbere ni sBS. Niba ubukonje buvanga byatumen buhagarikwa isaha imwe nyuma yo gukangura, isukuye barrel ikangura, ongeraho amazi meza, kandi usukure umuryango. Andika amazi nyuma, kandi wibuke ko nta mazi akusanya mu ndobo kugirango wirinde ibyo uhindura, bigatera ihuriro nubundi buryo bigaragara ko ari ingese. Mugihe uyikoresha ukurikije amabwiriza, ugomba gufata ingamba zoroshye kugirango wirinde igihombo bitari ngombwa mubikorwa.

Ihame rishinzwe ibikoresho bya Emulsion Ibikoresho:
Imbaraga zo mu butaka bw'ibikoresho bya emalsion bya bitumen n'amazi biratandukanye cyane, kandi ntibishoboka hamwe n'ubushyuhe busanzwe cyangwa bwo hejuru. Igihe igihingwa cya emulsion cyatumen gikorerwa imitungo nka centrififution, no kugira ingaruka, ibikoresho bya emulsion bizahinduka ahantu hatangiriyeho. Shanxi yanze ubukonje bukonjesha amabara ya bitumen ku ngingo zifatika, imitingito hagati ya bitumen iragabanuka, kugira ngo ibyuma bikonje bya bitumen bigabanuka, kugirango mvange ikonjesha bitumen ituje mu mazi. , ibikoresho bya emulsion bitumen ni amavuta-y'amazi. Sisitemu yo gutatanya ni ibara ryijimye, hamwe na bitumen ikonje nkicyiciro cyatatanye n'amazi bikomeza, kandi bifite amazi meza mu bushyuhe bwicyumba. Ibikoresho bya emalsion bitumen mu buryo bumwe, ibikoresho bya emalsion bikoreshwa mu "gutatana" kuvanga ubukonje bwa bitumen n'amazi, bityo bihuza amazi yo kuvanga ibikonje bya bitumen.

Ibimera bya bitumen bishyushye bishyushye-gushonga ubukonje-kuvanga amabara ya bitumen, hanyuma ugatatanya amabara ya bitumen mu mashini ikubiyemo amashini ikubiyemo amashanyarazi akonje ya bitumen. Cement yamaganye birumen ibikoresho bya butumen bikoreshwa mumiterere ya slab ballastless ikoresha igihingwa cya catic emulsion. Mu rwego rwo guhuza delastique, gukomera n'ubwiza bwa sima byagaragaje akamaro biturumen, polymer bigakoreshwa mu guhindura bitumen.
