Isimo sezindlela incike kokuhambisana asphalt izindlu ubuchwepheshe

Iqiniso ukuthi onjalo asphalt, isintu siye aziwa okwesikhathi eside. asphalt Yemvelo (entabeni resin ehlanganisa ingxube ibitume ngezinto amaminerali) asetshenziswa ngisho AbaseGibhithe lasendulo futhi abaseFenike njengendlela yokuhlanganisa e ukwakhiwa kanye nemikhumbi. South wamaNdiya aseMelika wasebenzisa asphalt ukuze impregnate ezikebheni zabo ngamanetha. Asphalt wasetshenziswa lamaGibhithe mummification, futhi e-East yayo kwakubhekwa njengesibusiso ikhambi. Ngaphezu kwalokho, i-asphalt yemvelo ekhishwe embhedeni Olufile, wasebenzisa (futhi uqhubeke nokusebenzisa) ukudala varnishes nopende.

Isicelo asphalt yokufakelwa (ibitume ingxube ohlangene, itshe ochotshoziwe, isihlabathi, amaminerali powder) njengoba indaba for izindlu umgwaqo waqala ngasekupheleni XIX leminyaka eYurophu nase-USA. Ngesikhathi esifanayo saqala ukusebenzisa asphalt futhi eRussia.

Yiqiniso, njengoba i-asphalt laying ubuchwepheshe, ukukhiqizwa yayo uye washintsha kakhulu, kodwa izimiso eziyisisekelo akukashintshi.

ukwakhiwa komgwaqo Modern

Isimo esibaluleke kakhulu ukuze traffic evamile yinqubo okwenza okuqinile komzila womgwaqo izakhiwo. Ngaphandle inzuzo evamile kwemigwaqo yesimanje egandayiwe cishe kungenakwenzeka, futhi ngenxa yalokho ukwakhiwa umgwaqo ovulekile kuyinto ebaluleke for yiliphi izwe.

Ukuhambisana asphalt laying ubuchwepheshe kanye nokusebenza ngendlela zihlobene ngokuqondile zokukhiqiza izinga ukulawula impahla esetshenziswa ukwakha izindawo zokuhamba asphalt. Ukwahluleka okuthobela nanoma Imiphumela ukuhluleka kwanoma umgwaqo.

I impumelelo yesayensi yanamuhla enze kube nokwenzeka ukuba njalo ngcono njengoba Ukwakheka wengxenye ye-asphalt, futhi lonke inqubo ukukhiqizwa kwemisebenzi komgwaqo.

Uma sikhuluma ubuchwepheshe asphalt, kwenziwa ngezigaba ezine:

• isizinda ukuqeqeshwa;
• amalahle asphalt ukuthambisa ke;
• ebeka i-asphalt esisekelweni;
• Rolling-asphalt compactor ngoba titibonelo letinkhulu tekuvumelana futhi ahlelembe ke.

Lapho beqeda lezi zinyathelo, the asphalt kumele kube isikhathi esithile ngaphambi angawokuphulukisa okuphelele nokuthola imvume amandla design.

Lobu buchwepheshe kusho imingcele eqinile ukuze izenzo, ukuhambisana izingqinamba zezulu Meteorological. Ukwehluleka ukulandela lezi zidingo (isib kahle ukustaka ukulandelana noma ngaphansi kwamazinga okushisa aphansi, emvuleni) kuholela yokuthi umgandayo izothatha kancane kunokujwayelekile.

Ngisho ekuhambisaneni konke asphalt ubuchwepheshe asikho isiqinisekiso sokuthi komzila womgwaqo akudingi yesondlo okwengeziwe futhi ukulungisa ngesikhathi esifanele.

Ukusetshenziswa asphalt abandayo ukuze kulungiswe umgwaqo

Le nto esanda kutholakala ezweni lethu. Yenziwe esiku asphalt polymer-modified nge wanezela kwakheke isithwathwa plasticizing izithasiselo. Cold asphalt laying ubuchwepheshe kube lula inqubo silungisa endleleni, ngoba ivumela ukuba enze ngendlela ezibanzi lokushisa ububanzi. It ingafakwa ngaphansi kwamazinga okushisa aphansi (-15 ° ^C). Ngaphezu kwalokho, imisebenzi emgwaqweni kungenziwa kwenziwe nemvula. Laying asphalt abandayo akudingi pre-ukwelashwa bese enamathela primer lalungiswa. Kodwa inzuzo ebaluleke kakhulu ukuthi asphalt abandayo, - ubuchwepheshe nokubeka le nto ayidingi imishini ekhethekile. Kwanele uthele pothole noma umgodi futhi lokwela angabekwa, ngemva kwalokho inqubo polymerization iqala kanye asphalt Uqinisa ngokushesha. Njengoba ngentengo, uma kuqhathaniswa ne izindleko yesondlo zesikhathi imigwaqo asphalt ezivamile, kuvela ukuthi ukusetshenziswa asphalt abandayo kuyoba eshibhile ngisho.
