Kunezinhlobo eziningi ze-asphalt emakethe, ngakho-ke kungakanani esikwaziyo mayelana nomgomo wokukhiqiza we-asphalt yenjoloba? Ake sibheke ndawonye.
I-Rubber asphalt iyisibophezelo se-asphalt esiguquliwe esakhiwe ngokuqala ukucubungula isondo lokuqala lemfucuza libe yimpushana yerabha, bese lilihlanganisa ngokwesilinganiso esithile esimahhadla futhi esihle sokugreda, yengeza izinhlobonhlobo zezilungisi ze-polymer eziphakeme, nokuncibilika nokuvuvukala ngokugcwele ngetiyela le-matrix. ngaphansi kwezimo zokushisa eziphezulu (ngaphezu kuka-180 ° C) ngokuxuba okugcwele. Ngokuvamile kuqondwa njenge-asphalt enerabha eyengeziwe. I-asphalt yerabha inokuzinza okuphezulu kwezinga lokushisa, ukuguquguquka okuphansi kwezinga lokushisa, ukulwa nokuguga, ukulwa nokukhathala, nokumelana nokulimala kwamanzi. Kuyimpahla egandayiwe evumelana nemvelo futhi isetshenziswa kakhulu ongqimbeni lokumunca ukucindezeleka kanye nongqimba olungaphezulu lwezakhiwo zomgwaqo.

Kunemiqondo emithathu edumile "yetiyela lenjoloba": "indlela eyomile" itiyela lenjoloba, "indlela emanzi" itiyela lenjoloba, kanye "nendlela yokuxuba idepho ye-asphalt" itiyela lerabha.
(1) "Indlela eyomile" i-asphalt yerabha iwukuxuba impushana yerabha ne-aggregate kuqala, bese wengeza itiyela ukuze uxutshwe. Le ndlela
ukubheka impushana yerabha njengengxenye yenhlanganisela, kodwa ngokuvamile inani lempushana yerabha alikwazi ukuba phezulu kakhulu. Le ndlela ayivamile ukusetshenziswa.
(2) "Indlela emanzi" i-asphalt yerabha iwukuxuba inani elithile lempushana yenjoloba netiyela kuqala, bese isabela ekushiseni okuphezulu ukuze kwakhiwe ingxube enezakhiwo ezithile. Njengamanje iyindlela esetshenziswa kakhulu ukukhiqiza itiyela lenjoloba.
(3) "Indlela yokuxuba idepho yetiyela" ibhekisela ekuxutshweni kwempushana yenjoloba kadoti netiyela elishisayo endaweni yokuhluza noma edepho yetiyela, bese iyiletha esiteshini sokuxubela ukhonkolo setiyela noma endaweni yokwakha. "Indlela yokuxuba idepho ye-asphalt" empeleni ingathathwa njengohlobo lokukhiqiza "indlela emanzi", kodwa ukusetshenziswa kwayo kwempushana yenjoloba engcolile ngokuvamile akudluli u-10%, ukusetshenziswa kwempuphu yerabha kuphansi, futhi i-viscosity iphansi kunaleyo ye-asphalt yenjoloba. ("indlela emanzi"). Ingxube ehlanganisiwe ayikwazi ukufeza ukusebenza okufanayo nengxube ye-asphalt yerabha.
Yiziphi izinzuzo ze-asphalt yenjoloba uma iqhathaniswa ne-asphalt evamile?
1. Imifantu ephikisayo
Kusendlalelo sokumunca ingcindezi ye-asphalt yerabha, inani eliphakeme letiyela lenjoloba liboshwe ngokuqinile netshe lezinhlayiyana zosayizi owodwa ukuze kwakheke ungqimba lwesakhiwo esibonisa ukuqhekeka okungaba ubukhulu obungu-1cm. Imifantu ehlukahlukene ongqimbeni oluzinzile lwamanzi noma indawo egandaywe ngosimende endala izokuthola kunzima ukungena kulolu ungqimba, olunganqanda ngokuphumelelayo ukubonakaliswa kwemifantu.
2. Ukonakala kwamanzi
Inani letiyela lenjoloba likhulu (2.3kg/m2), futhi ifilimu ye-asphalt cishe engu-3mm ukujiya izokwakhiwa phezu komgwaqo, okungavimbela ngokuphelele amanzi emvula ukuthi angangeni phansi futhi avikele umbhede womgwaqo. Okwesibili, lapho kugandaywa ingxube ye-asphalt kuyo, i-asphalt yenjoloba engaphezulu kwesendlalelo sokumuncwa kwe-asphalt yenjoloba izoncibilika okwesibili, futhi ngemva kokuba indawo yomgwaqo ihlanganiswe, izogcwalisa ngokugcwele igebe elingaphansi kwenhlanganisela engaphezulu. , ngaleyo ndlela kuqedwe ukuthi kungenzeka ukugcinwa kwamanzi phakathi kwezingqimba nokuvimbela umonakalo wamanzi.
3. Umphumela wokubopha
I-asphalt yerabha ine-viscosity enamandla kakhulu. Ingakhangiswa futhi iboshwe kungqimba oluzinzile lwamanzi noma umgwaqo omdala usimende ngokuqinile, ngaleyo ndlela idlala indima yokuhlanganisa nendawo yomgwaqo.
