Ibhitumene asphalt. Brands neempawu yebhitumene

Zonke iintlobo asphalt isetyenziswe njani ukugxininisa roadbed, kuba ngokuyintloko inamacandelo amabini: itha kunye kwezimbiwa aggregate. Le yokugqibela yenziwe ngokwemigangatho GOST 9128 ukusuka izinto ezomeleleyo kakhulu. Itha asphalt ingasetyenziselwa yemiyinge ezahlukeneyo.

Iimpawu zobugcisa

Ibhitumene ngokuqhelekileyo kwenzeka kufuphi namasimi oyile ngokohlobo lens. Noko ke, ushishino kunye nolwakhiwo wendlela kaninzi basebenzisa inguqulelo sesibini salo mbandela - ngumntu. Yenza itha kwimveliso oyile. Ngokuqhelekileyo oku tar izicatshulwa neoli zesinyibilikisi-ecokisiweyo.

Ukubunjwa asphalt ezahlukeneyo

Ukubunjwa umxube obumiselwe enkulu endleleni, ukongeza itha kungahlanganisa amacandelo ezifana ngesanti luhlalu. Ukusebenzisa kuqala bokwenziwa igada isanti. Maxa wambi umxube kwakhona wongezelela kwezimbiwa umgubo kunye ingqushu. Olu uhlobo oluxhaphakileyo nenethiwekhi. Oku kuthiwa Musiqisi otyunyuziweyo ngamatye. Kwakhona eli izinto ndlela ngamanye amaxesha wenza usebenzisa luhlalu. Le umxube kulo mzekelo idityaniswe inkunkuma kunye nomgubo bezimbiwa. Asphalt olu hlobo kuthiwa luhlalu.

Kuxhomekeka injongo umxube ratio kula ziyahluka. Ngoko ke, ngokuba neendledlana asphalt kusetyenziswa bokwenziwa usebenzisa isanti kunye luhlalu. Umaleko esezantsi izithuthi yenziwa ngomxube sisincoko eyahlukileyo kancinane. Kulo mzekelo, le tela eyenziwe kunye nokusetyenziswa yimiwewe elikhulu kunene kuphela. Le nwebu batyhileka kwiindlela igada egudileyo. Oku kuquka nezohlwayo ingqushu.

Mark ibhitumene asphalt

Ngenxa yoko, uhlobo lokufaka kusetyenziswa ephembelela amandla olu hlobo lwezinto, yaye ngenxa yoko, intsimi isicelo sayo. Nangona kunjalo, akukho ixhomekeke ngaphantsi kraca nokwakhiwa asphalt nomgangatho wayo podmeshennogo kuye ngetha. Kuba imveliso kwimixube elolu hlobo ngokuqhelekileyo lolu hlobo ethile esetyenzisiweyo. Libizwa ngokuba indlela itha kunye ephawulwe oonobumba nerd. Parameter engundoqo ngayo izinto ehlelwe yi obushushu.

Phantsi kweemeko ezithile, ngaphandle kokukhetha, aqale anyibilike ngetha. Ngokuxhomekeka ekubeni, ukuba kunini kungekehli, impahla ingasetyenziswa kummandla othile kwelo lizwe. Ukuze ukuqonda oko iimeko ungasebenzisa ukuba tar ethile ukuze asphalt kuqala makajonge uphawu yakhe. Inkcaza ku amanani ayo bonisa uluhlu viscosity lo mbandela. Okwangoku, imveliso asphalt kusetyenziswa kuzo zonke ezintlanu iintlobo yebhitumene wendlela nerd 40/60, 60/90, 90/130, 130/200, 200/300. I shushwana imozulu, izinto viscous ngakumbi ukuba isetyenziswe ukuvelisa nokufakelwa.

Kakade ke, le tela kwi asphalt kufuneka abe khona ngobuninzi ngokwaneleyo. enkulu kakhulu yale zokufunda ukulungiselela kwimixube azisetyenziswa ngokuqhelekileyo. Inxalenye eshushu yokukwazi kufuneka saa kwaye unamathele kunye. Kodwa ke, ukuba akukho ngokwaneleyo yebhitumene kwi asphalt ekugqibeleni ukuqala ukwenzeka zonke iintlobo iinkqubo ezimbi. Utyhutyha amanzi kunye yingqele ebusika, nihlinza kuyo.

Eyona engundoqo iimpawu nerd

Ngaphandle viscosity ngebhitumene asphalt luphawulwa iimpawu ezifana nezi:

• Ductility. Eli nani kumiselwa umgama apho itha ke wafika umsonto ngaphandle komsipha yayo. Kunokuba kunjalo, kungona adhesiveness lo mxube. bitumens Road ngokuqhelekileyo kufumana ductility mkhulu kuno-40 cm. Iimfuno kwesi salathisi ukuba nerd ebekwe kwi-0 ° C

• iimpawu Deformation. Ekumiseleni ukufaneleka ibhitumene asphalt kwaso ukunikela ingqalelo kwiimpawu zawo ezifana luthambe, enyakanyakeni, ductility, brittleness, njalo njalo. D. Zimisela iimpawu deformation lo mbandela. Ngeli ngokushushubeza le bhitumene yokugqibela kufuneka ezingaguquguqukiyo kakhulu.

imixube Ulwelo ekwakheni

Ibhitumene asphalt ayidli iqondo eliphezulu kakhulu viscosity. Noko ke, maxa wambi kusetyenziswa xa egalela Ipeyinti kunye neentlobo lulwelo kwale nto. Zisebenza ikakhulu ukoluka ixesha imisebenzi yendlela. Ibhitumene engamanzi kusenziwa ngokwemilinganiselo ezithile yongezwe viscous. Ngenxa yoko, ukutyabeka kwiqondo lobushushu aphantsi ayithethi kakhulu ngokukhawuleza lukhuni. Ibhitumene engamanzi yenziweyo kongezwe amaqhekeza distillate viscous.

Xa umsebenzi wokulungisa kananjalo basebenzisa viscosity eliphakathi. Isetyenziswa yonyango sele lise imephu. Izinga sesicelo yebhitumene ukuba ngokubekwa asphalt kule meko ayikho inkulu kakhulu kwaye 0.5 kuphela l / ^m2.

Ziziphi kwezithako inokuba khona nerd

Ekuvelisweni yendlela yebhitumene, phakathi kwezinye izinto, ingasetyenziswa zizo zonke iintlobo kwezithako. Kuyafuneka ukuba utshintshe iimpawu ezahlukeneyo zokufunda. Umzekelo, oku kusetyenziswa ngetha, nto leyo ibandakanya ekulungiseni udweliso lweenkqubo ekwenziweni asphalt ebandayo. Ngenxa yesicelo yabo emva Wayephilisa ukutyabeka akuthethi ngothanda kwi ukubanda nobushushu akukho zinyibilike. Xa usebenzisa ongeziweyo Mac-ngebhitumene uzuza iipropati yayo yokugqibela kakhulu ngokukhawuleza.

Yintoni zongezwe ibhitumene asphalt na? lobeko umdla kakhulu le nto ifunyenwe kwimeko emigutyeni yezimbiwa ezinemibala asetyenziswa kwinkqubo yokuvelisa. Ukusuka oku kuvela ngebhitumene Musiqisi omhle kakhulu. Mnikele kwiipaki, iindlela ibhayisekile, kwakunye esetyenziselwa womshicileli.
