I-asphalt/i-bitumen kwinto esusiweyo inokuphinda isebenze kwaye iphinde isetyenziswe kwimixube emitsha yendlela. Ngama-95% eendlela ezenziwe ngeasphalt okanye ezityelwe ngeasphalt, isixa esikhulu sezinto zeasphalt ezenziwe ngeasphalt ziyabuyiselwa minyaka le. Ngokophando olwenziwa minyaka le yiFederal Highway Administration kunye neNational Asphalt Pavement Association, ngaphezulu kwe-99% ye-asphalt esuswa minyaka le kumphezulu wendlela ngexesha lokwandiswa kunye neeprojekthi zokuphinda zisetyenziswe kwakhona njengenxalenye yeendlela ezintsha, iibhedi zendlela, amagxa kunye neendonga.
