Bhitumini yakagadziridzwa inoreva musanganiswa weasphalt pamwe nekuwedzera kwerabha, resin, yakakwirira molecular polymer, yakatsetseka yakatsetseka yerabha poda uye mamwe ma modifiers, kana kushandisa yakapfava oxidation processing yebhitumini kuvandudza kushanda kwebhitumini. Iyo pavement yakarukwa nayo ine yakanaka durability uye abrasion kuramba, uye haipfave pakupisa kwakanyanya kana kutsemuka pakudziya kwakaderera.

Kuita kwakanakisa kwebhitumini yakagadziridzwa kunobva kune modifier yakawedzerwa kwairi. Iyi modifier haigone kungobatana chete pasi pechiito chekushisa uye kinetic simba, asiwo inopindirana nebhitumini, nokudaro inovandudza zvikuru michina yebhitumen. kungofanana nekuwedzera simbi dzesimbi kune kongiri. Kuti udzivise kupatsanurwa kunogona kuitika mune general modified bitumen, iyo bhitumini yekuchinja maitiro inopedzwa mune yakakosha nharembozha. Musanganiswa wemvura une bhitumini nemodhifiri unopfuudzwa nepaguyo recolloid rizere nemakorokoza. Pasi pechiito chehigh-speed rotating colloid mill, mamorekuru emodhifita anotsemuka kuti agadzire chimiro chitsva obva aiswa kumadziro ekukuya obva adzokera kumashure, akanyatsosanganiswa mubhitumini. Kutenderera uku kunodzokororwa, izvo zvisingaite chete kuti abitumen uye iyo gadziriso inowana homogenization, uye ma molecular cheni emodhifita anodhonzwa pamwe chete uye akagoverwa mumambure, izvo zvinovandudza simba remusanganiswa uye kuwedzera kuneta kuramba. Kana vhiri richipfuura pamusoro pebhitumini yakagadziridzwa, bhitumini layer inopindirana zvishoma. Kana vhiri richipfuura, nekuda kwesimba rakasimba rekubatanidza rebhitumini yakagadziridzwa kune aggregate uye yakanaka elastic kupora, chikamu chakadzvanywa chinokurumidza kudzoka kune flatness. chimiro chepakutanga.
Bhitumini yakagadziridzwa inogona kunyatso kusimudzira huwandu hwemutoro wepavhu, kuderedza kuneta kwepavhu kunokonzerwa nekuremedza, uye kuwedzera zvakanyanya hupenyu hwesevhisi. Naizvozvo, inogona kushandiswa zvakanyanya mukugadzira migwagwa mikuru-giredhi, nhandare dzendege, uye mabhiriji. Muna 1996, bhitumini yakagadziridzwa yakashandiswa kugadzira nzira yekumabvazuva yeCapital Airport, uye mugwagwa unoramba uripo nanhasi. Kushandiswa kwebhitumini yakagadziridzwa mumigwagwa inopindika kwakwezvawo pfungwa huru. Iyo void rate ye permeable pavement inogona kusvika 20%, uye yakabatana nemukati. Mvura inonaya inogona kukurumidza kunyudzwa kubva munzira pamazuva ekunaya kudzivirira kutsvedza uye kupfachuka paunenge uchityaira. Kunyanya, kushandiswa kwebhitumini yakagadziridzwa kunogonawo kuderedza ruzha. Mumigwagwa ine mavhoriyamu akati wandei, chimiro ichi chinoratidza zvakanakira.
Nekuda kwezvinhu zvakaita sekusiyana kwetembiricha yakakura uye kuzunguzika, akawanda mabhiriji decks anochinja uye anotsemuka nguva pfupi mushure mekushandisa. Kushandiswa kwebhitumini yakagadziridzwa kunogona kugadzirisa dambudziko iri. Yakagadziridzwa bhitumini chinhu chakakosha chakakodzera kumigwagwa mikuru-giredhi uye nhandare dzendege. Nekukura kwebitumen yakagadziridzwa tekinoroji, kushandiswa kwebhitumini yakagadziridzwa kwave kubvumirana kwenyika dzepasirese.
