Andazi ukuba yintoni "ungqimba lwamacala amdaka, ungqimba olunamathela, kunye nomenzi wophawu?
Makhe sithethe ngokulandelelana kolwakhiwo kuqala. Ioyile ye-arheer efihliweyo kufuneka itshiswe ngaphakathi kweeyure ezi-6 emva kokuba isiseko senziwe. Ioyile ye-famiment yeoyile isebenzisa i-SPUP PC-2. Isixa semali sinokumiselwa ngokutshiza kwi-1.5 yeelitha kwimitha nganye yesikwere, kwaye ubunzulu be-Penetion ayingaphantsi kwe-5mm. Emva kokutshiza i-oyile ye-faceter efihlakeleyo, i-SAPOPCHT PC-1 I-TARTE YOKUGQIBELA IQHUTYELWE. Isixa se-sphalt e-Asphalt i-1.0 iilitha kwimitha nganye yesikwere, ubungakanani be-aggregate i-0.5 ukuya kwi-1 ukuya kwi-1cm, kwaye ubukhulu akufuneki bube ngaphantsi kwe-0.6 cm. Phambi kokuba ikhonkrithi ye-asphalt, ioyile yobunamatheliso kufuneka ifakwe kwiindawo ezingaphezulu nangaphantsi komgangatho ongezantsi wokungena kunye namacala ee-curbs, iindawo zokujonga amanzi omhlaba kunye nezinye izinto. Ioyile yokunamathela i-oyile isebenzisa i-PHC i-Asphalt Pc-3, idosi yeelitha eziyi-0,5 kwimitha nganye yesikwere.
Ungqimba olungenamsebenzi
Umsebenzi we-maketer enobungozi kukwenza i-asphalt ye-asphalt ye-asphalt ye-asphalt kunye ne-Asphalt Base Boct Well kakuhle. Ngumbambi omncinci ongena kumphezulu we-One Malimer ngokuthulula i-asphalt e-asphalt asphal, i-coal tar okanye i-alphalt ye-asphalt kwi-Asphalt kwi-Base.
Iimeko apho kufuneka i-asphalt ye-asphalt ifanele ithulule ngolu hlobo lulandelayo:
.
.
.
Umaleko wobumbeleleyo
Umsebenzi wokunamathela ekwenzeni iindawo ezingaphezulu nezezantsi ze-asphalt okanye i-asphalt ye-asphalt ye-asphalt kunye nesakhiwo (okanye i-cemetion yekhonkrithi) iyonke.
Iimeko apho kufuneka igalelwe i-asphalt ene-asphalt imi ngolu hlobo lulandelayo:
.
. Okanye ngaphambi kokupeyinta idesika yebhulorho.
.
.
Indima yeTywina:
(1) ukutywina umaleko othile ukuba udlale indima ekugcinweni kwamanzi kunye nokuphuma kwamanzi;
.
(3) ukuqiniswa kweenxalenye ezikhululekileyo zomphezulu othile wendlela onakelelwe;
.
Umaleko weTywina unokwahlulwa abe ngumlinganiso wetywina ophezulu kunye nobeko lwetywina eliphantsi; Malunga nohlobo lolwakhiwo, indlela yonyango lwe-commar enye yonyango lokuxuba okanye ukuhambisa i-sulther kunokusetyenziswa, okanye i-asphalt ekhutshiweyo isetyenzisiwe. Itywina le-Green Slide.
Kwindawo enemvula kunye nemiswakalo, i-asphalt ye-asphalt ye-asphal yeendlela kunye neendlela zokuqala zokuqala zinomntu okhululekileyo kwaye kunokwenzeka ukuba ubone amanzi. Okanye xa i-asphalt ye-asphal ayinakubakwa ngexesha ngexesha lokwakhiwa komaleko wesiseko kunye nezithuthi kufuneka zidlule, kuyacetyiswa ukuba ubeke itywina elingaphantsi emva kokutshiza umaleko ongenamkhenkce.
Ungqingo lwetywina olusezantsi lusetwe kumphezulu we-semi-rigrafid osisiseko sokukhusela umaleko wokukhusela izithuthi zokwakha, ukuphepha unxulungo lwemvula, kwaye luqinisekise unxibelelwano phakathi komgangatho kunye nomaleko ophakathi. Zininzi iindlela zokwakha zomaleko ongezantsi.
Umaleko weTywina ongaphezulu kufuneka ubekwe kwi-asphalt ye-asphalt ye-asphalt kule meko zilandelayo:
.
(2) I-Asphalt ye-Asphalt ye-Asphalt ene-rocks okanye ukulungiswa.
