Ukutywinwa kwenkungu yindlela yokugcinwa kwendlela enoluhlu olubanzi lwezicelo. Isetyenziswa kakhulu kwiindlela ezinokukhanya ukuya kwimodareyitha yezohlwayo ilahleko okanye imathiriyeli ekhululekileyo. Umzekelo, xa i-asphalt pavement ikhululekile, i-fog seal layer inokusombulula ingxaki; njengomgangatho oshinyeneyo womxube we-asphalt kwindawo egugayo ephawulweyo, umphezulu womaleko wegrabile, umphezulu womxube we-asphalt ovulekileyo, njl. njl. kunye nelahleko eyongezelelekileyo, kunye nokungenwa kwamanzi kunyukile. Amanzi ahamba ngeenyawo aya kungena kumxube we-asphalt ngokusebenzisa iintanda okanye umonakalo odibeneyo, obangela iintanda, iintanda, kunye neMibhobho kunye nezinye iimeko zepavumente apho ubume bepavumente busebenza kakuhle.
Umatshini wokulungisa umaleko wenkungu: Uninzi lwendlela ye asphalt ikhula ngokukhawuleza kwiminyaka yokuqala eyi-2-4 yokusetyenziswa, ibangela malunga ne-1CM ye-asphalt kumphezulu wendlela ukuba ibe brittle, ibangele ukuqhekeka kwangaphambili, ukukhulula kunye nomnye umonakalo kumphezulu wendlela, kunye namanzi okuqala. umonakalo kumphezulu wendlela. Izifo, ngoko ke iminyaka emi-2 ukuya kwe-4 emva kokuba i-asphalt ivuleleke kwi-traffic ixesha lokugcina i-fog seal layer. Kufuneka kumiselwe ngokuthe ngqo ngokusekelwe kuphando lwezifo eziqhelekileyo zesakhiwo kunye nokusebenza kwendlela yokuhamba, isalathisi semeko ye-pavement PCI, i-international flatness index IRI, ubunzulu besakhiwo, iimeko zokunxiba kunye nokukrazula kunye nezinye izinto.
Umsebenzi womaleko wokutywinwa kwenkungu:
(1) Isiphumo sokungangeni manzi, esinokunciphisa ngokufanelekileyo umonakalo wamanzi kumphezulu wendlela;
(2) Isixhobo sotywino lwenkungu sinokungeneka kakuhle kwaye sinokuzalisa iintanda ezicolekileyo kunye nezikhewu ezingaphezulu kumphezulu wendlela;
(3) Emva kokwakhiwa komaleko wetywina lenkungu, amandla okudibanisa phakathi kwee-aggregates kumaleko omgangatho we-asphalt anokwandiswa, asebenze njenge-asphalt yokuvuselela ngokutsha kunye nokukhusela i-asphalt endala ene-oxidized;
(4) Ukwakhiwa komaleko wetywina lenkungu kunokuwenza mnyama umphezulu wendlela, ukwandise umahluko wombala wendlela, kunye nokwandisa ukunethezeka okubonakalayo komqhubi;
(5) Ukuphilisa ngokuzenzekelayo iintanda ngaphantsi kwe-0.3MM;
(6) Iindleko zokwakha ziphantsi kwaye ubomi benkonzo bendlela bunokwandiswa.
Iindlela zokwakha kunye nezilumkiso:
(1) Ilori ekhethekileyo yokutshiza okanye isixhobo sokutshiza esikhethekileyo somaleko wokutywina inkungu kufuneka isetyenziswe ukutshiza imaleko yokutywina inkungu ngokomlinganiselo wokutshiza.
(2) Iincam zokutshiza kwindawo yokuqala neyokuphela kolwakhiwo zifanele ziqinisekiswe ukuba zicocekile, yaye ioli eshukumayo ifanele ibekwe kwangaphambili kwindawo yokuqala neyokuphetha.
(3) Ukuba ukunaba okunemigca okanye ukuvuza kwezinto kwenzeka, ukwakhiwa kufuneka kumiswe ngokukhawuleza ukuze kuhlolwe.
(4) Ixesha lokuphilisa lomaleko wetywina lenkungu kufuneka limiselwe ngokohlobo lwemathiriyeli kunye neemeko zemozulu, kwaye inokuvulwa kwizithuthi kuphela emva kokuba yomisiwe kwaye yenziwe.
