Nebitume * laba asphalt. Brands nezakhiwo ibitume

Zonke izinhlobo asphalt esetshenziswa baqinise roadbed, ngokuyinhloko tincenye letimbili: ibitume nokumbiwa ekuhlanganisweni. Lesi sakamuva yenziwa ngokuvumelana GOST namazinga 9128 kusuka impahla okuhlala kakhulu. Incwadi uma ikhuluma ngebitume asphalt ingasetshenziswa amagama emikhiqizo ehlukahlukene edayiswa.

Izici yobuchwepheshe

Ibitume lemvelo litholakala zivamise ukwenzeka eduze namasimu uwoyela ngesimo lens. Nokho, umkhakha nokwakhiwa umgwaqo kaningi wasebenzisa inguqulo yalesi impahla yesibili - yokufakelwa. Yenza ibitume kusuka imikhiqizo uwoyela. Ngokuvamile lokhu itiyela ezikhishwe namafutha kuphela-acwengekile.

Ukwakheka asphalt futhi ezahlukeneyo zalo

Ukwakheka ingxube emiselwe izindlu komgwaqo, ngaphezu ibitume kungafaka izingxenye ezifana isihlabathi futhi amatshe. Ukusebenzisa lokuqala ekhiqizwa isihlabathi asphalt. Ngezinye izikhathi ingxube nalo wanezela amaminerali powder kanye imfucumfucu. Lena owande kakhulu Ukusabalala. Lokhu kubizwa ngokuthi i-asphalt ochotshoziwe itshe. Futhi le nto umgwaqo ngezinye izikhathi wenza usebenzisa amatshe. Ingxube kulesi simo waba ukungezwa imfucumfucu kanye powder amaminerali. Asphalt zilwane libizwa uhlalwane.

Kuye injongo ingxube isilinganiso ncenye ziyahlukahluka. Ngakho-ke, zokuhamba ezisetshenziswa asphalt ekhiqizwa usebenzisa isihlabathi esihle futhi amatshe. Isendlalelo engezansi ingxenye yomgwaqo ebekelwe izimoto ngokuvamile wawenziwa ngengxube ye Ukwakheka ukuhluka. Kulokhu, the asphalt enziwe ukusetshenziswa kuphela imfucumfucu esikhulu kakhulu. Isendlalelo engenhla elachithwa emigwaqweni asphalt abushelelezi. Kuhlanganisa imfucumfucu inhlawulo.

Mark nebitume * laba asphalt

Ngakho, uhlobo yamathebhu wasebenzisa ithonya namandla yalolu hlobo lwezinto, futhi ngenxa yalokho, uhlelo lwayo lokusebenza ensimini. Nokho, indlela yokwakheka asphalt futhi izinga layo engengaphansi sincike brand podmeshennogo kuye itiyela. Ukuze kukhiqizwe Izingxube yalolu hlobo ezisetshenziswa mathiriyeli lo uhlobo oluthile. Ibizwa ngokuthi itiyela emgwaqeni kanye ephawulwe izinhlamvu BND. Umngcele we-main lapho impahla oluthathwa kuyinto lokushisa.

Ngaphansi kwezimo ezithile, ngaphandle kokukhetha, baqala ancibilike itiyela. Kuye ngokuthi, ngasiphi iphuzu kwenzeka, indaba ingasetshenziswa endaweni ethize yezwe. Ukuze ukwazi ukubona kulokho izimo ungasebenzisa ukuthi itiyela ethile asphalt kufanele siqale sibheke uphawu lwakhe. Yethula izibalo wakhe ubonise uhla viscosity into. Okwamanje, ukukhiqizwa asphalt asetshenziswa kuzozonke izinhlobo ezinhlanu ibitume umgwaqo BND 40/60, 60/90, 90/130, 130/200, 200/300. I ibavuthela isimo sezulu, impahla viscous ngaphezulu ozofakwa ekukhiqizeni izindlu.

Yiqiniso, i-asphalt in the asphalt kufanele babekhona eliningi eyanele. Ukuzifaka kakhulu le ndaba ukulungiswa Izingxube kungukuthi ajwayele ukusetshenziswa. Ingxenye esishisayo izindlu kufanele zisabalale hhayi banamathelane. Nokho, uma akwanele ibitume in the asphalt ekugcineni ziqala ukwenzeka zonke izinhlobo izinqubo okungekuhle. It lingena amanzi umnkantsha ebusika, edwengula ke.

I izakhiwo eziyinhloko we BND

Ngaphandle viscosity ibitume asphalt libhekene izakhiwo ezifana:

• Ductility. Lesi sibalo kunqunywa ibanga lapho ibitume kungenziwa nofunda intambo ngaphandle ukudabuka yayo. Ube ncono kunaloko longiko, ayanda adhesiveness ingxube. bitumens Road ngokuvamile ngezinga elithile ductility okukhulu kuka-40 cm. Izimfuneko kule inkomba BND lishone 0 degrees C.

• Deformation izici. Ekunqumeni nokufaneleka nebitume * laba asphalt womshini benaka izakhiwo zalo ezifana kuyaqina, ungangena, ductility, brittleness, nokunye. D. Yizo ezinquma izici ukusonteka material. Phakathi amalahle ibitume yokugcina akufanele ziyahlukahluka kakhulu.

ukwakhiwa Liquid ekwakheni

Nebitume * laba asphalt ngokuvamile ngezinga eliphezulu kakhulu viscosity. Nokho, ngezinye izikhathi asetshenziswa lapho ethela ezinengilazi nezinhlobo liquid le nto. Uzisebenzise ikakhulu ukuba zinde isizini imisebenzi komgwaqo. Ibitume eliwuketshezi ngezabelo ezithile yengezwe viscous. Ngenxa yalokho, luthi alufane at okushisa aphansi akusho stiffen ngokushesha. Ibitume eliwuketshezi kuveza ukwengeza viscous distillate izingxenyana zaso.

Lapho umsebenzi wokulungisa liyasetshenziswa naphakathi viscosity impahla. Isetshenziselwa ukwelapha kakade usule imephu. Izinga lokusebenza ibitume laying asphalt kulokhu akuyona likhulu kakhulu futhi l 0.5 kuphela / ^m2.

Yini izithasiselo okungenzeka khona BND

Esikhathini ukukhiqizwa umgwaqo itiyela, phakathi kwezinye izinto, ingasetshenziswa i- zonke izinhlobo izithasiselo. Basuke edingekayo ukushintsha izakhiwo ezahlukene into. Ngokwesibonelo, ibitume isetshenziswa, esakhiwa ukulungisa izingxenye enkulu ekwakhekeni asphalt abandayo. Ngenxa yalokho kwesicelo sabo emva elapha enamathela akusho crack emakhazeni kanti ukushisa akusho ancibilike. Uma usebenzisa izithasiselo MAC-ibitume ozuza impahla yayo yokugcina isheshe.

Yini ukungezwa ku nebitume * laba asphalt okunye? okufana Very interesting kwale nto etholwe esimweni izimpushana amaminerali ezinemibala asetshenziswa senqubo yokukhiqiza. Kule kuvela enhle kakhulu itiyela asphalt. Wamfaka amapaki, bike izindlela, kanye esetshenziselwa yomdwebo.
