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 wesendlalelo anama-adhesive kumele afafazwe ezingxenyeni ezingenhla zesendlalelo esingezansi esisezingeni eliphansi futhi ezinhlangothini zezakhiwo ezinjengezihlalu, izindawo zokuhlola, kanye nemithombo yokuhlola, kanye nemithombo yokuhlola. Amafutha engqimba anama-adhesive asebenzisa i-esphalf asphalt PC-3, futhi inani liyimitha yesikwele. 0.5 amalitha.
Isendlalelo esivumelekile: Umsebenzi wesendlalelo esivumelekile ukwenza ungqimba lwe-asphalt surface kanye ne-non-asphalt izinsiza zezinto ezilinganayo. 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
Izimo lapho kufanele kuthulwe khona i-adhesive asphalt kungokulandelayo:
.
(2) Ungqimba lwe-asphalt lungezwe engxenyeni edala ye-asphalt. noma ibhuloho ngaphambi kokuvula.
.
(4) izinhlangothi zamatshe amatshe, ama-inlets angamanzi emvula, imithombo yokuhlola, njll.
Ungqimba wokuvala uphawu: Indima yesendlalelo sokubekwa uphawu:
(1) Ukubopha uphawu oluthile lokudlala indima ekugcinweni kwamanzi nasekungeniswa amanzi;
.
(3) ukuqiniswa kwezindawo ezixegayo lapho ungqimba oluthile lomgwaqo lulimele futhi luhlukaniswe;
.
Ungqimba wokubopha uphawu lungahlukaniswa lube ungqimba olungaphezulu lokubekwa uphawu kanye nongqimba oluphansi lokuvalwa uphawu; Ngokohlobo lwezokwakha, indlela yokwelashwa engaphezulu yesendlalelo yendlela yokuxuba noma indlela ye-warder paving ingasetshenziswa, noma isendlalelo se-asphaldied asphalt slurry seamung singasetshenziswa.
Isendlalelo se-asphalt yemigwaqo emikhulu nemigwaqo emikhulu yokuqala ezindaweni ezinemvula kanye ne-poorpage enkulu futhi kungenzeka ibe nepasimu enkulu yamanzi, noma iveze lapho isisekelo singakwazi ukudlula khona, kudingeke ukuthi kudlule isisekelo se-asphalt ngemuva kokufafaza ungqimba olungavunyelwe ngowoyela.
Isendlalelo sendawo ephansi sisethwe ebusweni besisekelo se-semi-rigid ukuvikela isisekelo ekulimaleni izimoto zokwakha, yenza lula ukwelashwa kwezinto zokwakha, zivikele ukuvela kwamanzi emvula ukuthi ubheke ungqimba lwesakhiwo esingezansi, futhi uqinise ukuxhumana phakathi kwesendlalelo esingaphezulu nesisekelo. 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 ungqimba lokugqoka noma ungqimba oluvikelayo.
