Ngokweenkcukacha-manani, malunga ne-80% yohola wendlela ekudidi oluphezulu esele igqityiwe yavulelwa izithuthi kwilizwe lethu ziipavumente zeasphalt. Nangona kunjalo, ngophuhliso lwexesha, impembelelo yeemeko ezahlukeneyo zemozulu kunye nokusingqongileyo, kunye nesenzo semithwalo ephezulu yokuqhubela phambili, i-asphalt pavements iya kuhla. Ukwehla komgangatho ohlukeneyo okanye umonakalo uyenzeka, kwaye ukulungiswa kwendlela yendlela kukwamkela iindlela zobugcisa ezisebenzayo zokucothisa oku kuthotywa ukuze i-pavement ibe nokubonelela ngenkonzo elungileyo ngexesha lobomi bayo benkonzo.
Kuyaqondwa ukuba ezinye iinkampani eUnited States ziye zagqiba ngokulandelela uphando kumakhulu amawaka eekhilomitha zeendlela eziphakamileyo zamabanga ahlukeneyo kunye nenani elikhulu lokugcinwa kunye neenkcukacha zokulungisa: kwi-yuan nganye etyalwe kwiimali zokukhusela, 3-10 yuan inokugcinwa kwiimali zokulungisa kamva. isiphelo. Iziphumo zesicwangciso sobuchule sophando koohola bendlela baseUnited States nazo zibandakanyiwe kwinkcitho. Ukuba ulondolozo lothintelo lwenziwa ngamaxesha angama-3-4 ngexesha lonke lomjikelo wobomi bepavement, i-45% -50% yeendleko zolondolozo ezilandelayo zingagcinwa. Kwilizwe lethu, besisoloko "sigxininise kulwakhiwo kunye nokungahoywa kokugcinwa", nto leyo eyakhokelela kwinani elikhulu lomonakalo owenziwe kwangaphambili kumphezulu wendlela, ukusilela ukuhlangabezana nenqanaba lenkonzo efunekayo kuyilo, ukwandisa iindleko zokusebenza kwezithuthi zokusetyenziswa kwendlela, kunye nokubangela impembelelo embi ekuhlaleni. Ngoko ke, amasebe afanelekileyo olawulo lohola wendlela kufuneka anike ingqwalasela ekulungisweni koohola bendlela kwaye athintele kwaye anciphise izifo ezahlukeneyo kumphezulu wendlela, ukuze kuqinisekiswe ukuba imiphezulu yendlela yethu ineenkonzo ezilungileyo.
