Angazi ukuthi yini "isendlalelo esivumelekile, ungqimba olunamathela, kanye nongqimba wokubopha uphawu?
Ake sixoxe ngokulandelana kokwakha kuqala. Amafutha engqimba avumelekile kufanele afafazwe kungakapheli amahora ayi-6 ngemuva kokugoqwa kwesendlalelo sesisekelo. Uwoyela ovumayo ufaka uwoyela we-asphalt emulsold asphald-2. Inani linganqunywa ngokufafaza kwecala ku-1.5 amalitha imitha-skwele, futhi ukujula kokungena akuyona ngaphansi kuka-5mm. Ngemuva kokufafaza uwoyela wesendlalelo ovumayo, ungqimba lwe-asphalf asphalt PC-1 oluphansi luvinjelwe. Inani le-asphalt ekhuhlulisiwe ngu-1.0 amalitha imitha yesikwele, usayizi we-aggregate wandile ngu-0,5 kuya ku-1cm, futhi ubukhulu akufanele bube ngaphansi kwe-0,6 cm. Ngaphambi kokudonsa ukhonkolo we-asphalt, uwoyela we-adhesive ungqimba kufanele ufafazwe ezingxenyeni ezingenhla nezingaphansi zongqimba oluphansi lokuvalwa kokubopha kanye nezinhlangothi zama-curbs, izindawo zokugcina amanzi, imithombo yokuhlola kanye nezinye izakhiwo. Amafutha e-adhesive anamafutha asebenzisa i-esphall pc-3, enomthamo wamalitha ayi-0.5 amamitha skwele.
Ungqimba oluvumelekile
Umsebenzi wesendlalelo esivumelekile ukwenza ungqimba lwe-asphalt surfal kanye ne-non-asphalt basel Ungqimba oluncanyana olungena ebusweni bengqimba eyisisekelo ngokuthela i-esphall asphalt, i-coal tar noma i-asphalt ye-liquid kungqimba eyisisekelo.
Izimo lapho asphalt evumayo kufanele zithelwe zimi ngokulandelayo:
.
(2) usimende, lime, umlotha ondizayo nezinye izinhlabathi eziqinisi
(3) I-asphalt evunyelwe kufanele ithululwe esisekelweni esiqinile se-granular.
Ungqimba olunamathela
Umsebenzi wesendlalelo esinamathela ukwenza izingqimba ezingenhla ze-asphalt ezingenhla noma eziphansi noma ungqimba lwesakhiwo se-asphalt kanye nesakhiwo (noma usimende ukhonkolo) uboshwe ngokuphelele.
Izimo lapho kufanele kuthulwe khona i-adhesive argel asphalt imi ngalendlela elandelayo:
. (1
(2) Ukungeza ungqimba lwe-asphalt ku-Old Asphalt Pavement ungqimba. Noma ngaphambi kokuvula i-Bridge Deck.
(3) Ukuvula ungqimba lwe-asphalt engaphezulu kwendlela ekhonkolo ekhonkolo
.
Indima yesendlalelo sesendlalelo:
(1) Ukubopha uphawu oluthile lokudlala indima ekugcinweni kwamanzi nasekungeniswa amanzi;
.
(3) ukuqiniswa kwezingxenye ezixegayo zesendlalelo esithile somgwaqo ozonakele futhi kuhlukaniswe;
.
Isendlalelo se-samp singahlukaniswa ngesendlalelo se-wap sep ephakeme kanye nongqimba oluphansi lwesendlalelo; Ngokwezinhlobo zokwakha, indlela yokwelashwa engaphezulu yokwelashwa komhlaba wokuxubana noma wokuhlanganisa ungqimba ingasetshenziswa, noma i-asphalt emuhle ingasetshenziswa. I-Green Slurry Seal.
Ezindaweni ezinemvula nezomswakama, ungqimba lwe-asphalt lwe-asphalt lwe-Expredways kanye nemigwaqo emikhulu yokuqala ine-porolity enkulu futhi kungenzeka ukuthi ibonakale kalula amanzi. Noma lapho ungqimba lwe-asphalt elingaphezulu lungabekwa ngesikhathi sokwakhiwa kwesendlalelo sezinto nezimoto kudingeka kudlule, kungakuhle ukubeka ungqimba oluphansi lwesendlalelo ngemuva kokufafaza ungqimba olungavunyelwe ngowoyela.
Isendlalelo se-seal seal sisethwe ngaphezulu kwesendlalelo sesisekelo se-semi-rigid ukuvikela ungqimba lwesisekelo ekulinyazwe izimoto zokwakha, lula ukwelashwa kwezinto eziqinile, uvikele amanzi emvula ukuba avele engxenyeni yesakhiwo esingezansi, futhi aqinise ukuxhumana phakathi kwesendlalelo sobuso kanye nesendlalelo sesisekelo. Kunezindlela eziningi zokwakha zesendlalelo sendawo ephansi.
Isendlalelo se-Upper Seal kufanele sibekwe engxenyeni ye-asphalt ebusweni kulezi zimo ezilandelayo:
.
(2) Ukugembula okudala asphalt ngemifantu noma ukulungiswa.
(3) Indawo edala asphalt edinga ukubonwa ngengqimba yokugqoka ukuze athuthukise ukusebenza kwe-anti-skid.
(4) Indawo entsha ye-asphalt edinga ukubonwa ngesendlalelo sokugqoka noma ungqimba oluvikelayo.
