Ibitumen eguquliwe isho ingxube yetiyela enezelwa iraba, inhlaka, i-polymer yamangqamuzana amaningi, impushana yerabha egayiwe kahle nezinye izilungisi, noma ukusetshenziswa kokucutshungulwa kwe-oxidation okuncane kwebitume ukuze kuthuthukiswe ukusebenza kwetiyela. I-pavement egandaywe ngayo inokuqina okuhle nokumelana nokuhuzuka, futhi ayithambisi emazingeni okushisa aphezulu noma iqhekeke emazingeni okushisa aphansi.
Ukusebenza okuhle kakhulu kwetiyela eliguquliwe kuvela kusilungisi esingezwe kuso. Lesi siguquli asikwazi ukuhlanganisa kuphela omunye nomunye ngaphansi kwesenzo sokushisa namandla e-kinetic, kodwa futhi sisabela ngebitumen, ngaleyo ndlela sithuthukise kakhulu izakhiwo zemishini yetiyela. njengokwengeza izinsimbi zensimbi kukhonkolo. Ukuze uvimbele ukuhlukaniswa okungenzeka ku-bitumen eguquliwe evamile, inqubo yokuguqulwa kwebitumen iqedwa kumshini okhethekile weselula. Ingxube yoketshezi equkethe itiyela nesilungisi idluliswa emshinini wokugaywa ogcwele imifantu. Ngaphansi kwesenzo sesigayo se-colloid esiphendukayo esinesivinini esikhulu, ama-molecule esilungisi ayaqhekeka ukuze akhe isakhiwo esisha abese exhunywa odongeni lokugaya abese ebuyela emuva, ahlanganiswe ngokulinganayo etiyela. Lo mjikelezo uyaphinda, ongenzi nje kuphela i-abitumen kanye nokuguqulwa kufeza i-homogenization, futhi amaketanga e-molecular modifier adonswa ndawonye futhi asakazwe kunethiwekhi, okuthuthukisa amandla engxube futhi athuthukise ukumelana nokukhathala. Lapho isondo lidlula phezu kwebitumen eshintshiwe, ungqimba lwebitumen luba nokuwohloka okuncane okuhambisanayo. Lapho isondo lidlula, ngenxa yamandla okubopha aqinile etiyela eliguquliwe ekuhlanganiseni kanye nokululama okuhle kokunwebeka, ingxenye empintshiwe ibuyela ngokushesha ekucaba. isimo sokuqala.
Itiyela eliguquliwe lingakhuphula ngempumelelo umthamo womthwalo we-pavement, inciphise ukukhathala kwendlela egandaywayo ebangelwa ukugcwala ngokweqile, futhi andise ngamandla impilo yesevisi yendawo egandaywayo. Ngakho-ke, ingasetshenziswa kabanzi ekugandayweni kwemigwaqo emikhulu yezinga eliphezulu, imigwaqo yezindiza zezindiza, namabhuloho. Ngo-1996, itiyela eliguquliwe lasetshenziswa ukuze kugandaywe umgwaqo wezindiza osempumalanga we-Capital Airport, futhi umgwaqo usalokhu unjalo nanamuhla. Ukusetshenziswa kwebitumen eguquliwe emigwaqweni ekwazi ukungena emanzini nako kudonse ukunaka okukhulu. Izinga elingenalutho le-pavement evuzekayo lingafinyelela ku-20%, futhi lixhumeke ngaphakathi. Amanzi emvula angakhishwa ngokushesha endaweni egandayiwe ngezinsuku zemvula ukugwema ukushelela nokuchaphaza lapho ushayela. Ikakhulukazi, ukusetshenziswa kwebitumen eguquliwe nakho kunganciphisa umsindo. Emigwaqweni enezimoto eziningi uma kuqhathaniswa, lesi sakhiwo sibonisa izinzuzo zayo.
Ngenxa yezici ezifana nokuhluka okukhulu kwezinga lokushisa nokudlidliza, amadekhi amaningi amabhuloho azogudluka futhi aqhekeke ngokushesha ngemva kokusetshenziswa. Ukusetshenziswa kwebitumen eguquliwe kungaxazulula le nkinga ngempumelelo. Ibitumen eguquliwe iyinto ebalulekile efanelekile emigwaqweni emikhulu yezinga eliphezulu nemigwaqo yezindiza zezindiza. Ngokuvuthwa kobuchwepheshe bebitumen obuguquliwe, ukusetshenziswa kwebitumen eguquliwe sekuyisivumelwano samazwe emhlabeni jikelele.
