Ukuchaneka kwezinto ezinobunzima kwisityalo sokuxuba i-asphalt kuhambelana nomgangatho we-asphalt owenziweyo. Ngoko ke, xa kukho ukutenxa kwindlela yokulinganisa, abasebenzi bomenzi wesityalo sokuxuba i-asphalt kufuneka bahlolisise ngenyameko kwangethuba ukuze bafumane ingxaki.
Ukuba kukho ingxaki ngesinye okanye ngaphezulu kwezithathu zabenzi boluvo kwibhakethi yesikali, i-deformation ye-strain gauge ayiyi kufikelela kwisixa esifunwayo, kwaye ubunzima bokwenene bezinto eziza kulinganiswa buya kuba bukhulu kunexabiso eliboniswa ikhompyutha enobunzima. Le meko inokujongwa ngokulinganisa isikali kunye neentsimbi eziqhelekileyo, kodwa kufuneka kuqatshelwe ukuba isikali sokulinganisa kufuneka silinganiswe kwisikali esipheleleyo. Ukuba ubunzima bulinganiselwe, kufuneka bungabi ngaphantsi kwexabiso eliqhelekileyo lokulinganisa.
Ngexesha lenkqubo yokulinganisa, ukuguqulwa kwenzwa ye-gravity sensor okanye ukufuduka kwebhakethi yesikali kwicala lobunzima kuya kunqunyulwa, oku kunokubangela ukuba ubunzima bokwenene bezinto eziphathekayo bube bukhulu kunexabiso eliboniswe yikhompyutheni. Abasebenzi bomenzi wesityalo se-asphalt kufuneka baqale baphelise oku kunokwenzeka ukuze baqinisekise ukuba ukuguqulwa kwenzwa yomxhuzulane okanye ukufuduswa kwebhakethi yesikali ukuya kwicala lomxhuzulane akuthintelwanga kwaye akuyi kubangela ukutenxa kobunzima.
Izityalo zokuxuba i-asphalt kufuneka zisebenzise izixhobo zokusetyenziswa kwamandla aphantsi. Ukuveliswa kwe-asphalt kunye nezixhobo zokuthutha ezinobuchwepheshe obubalaseleyo njengengxolo ephantsi, ukusetyenziswa kwamandla aphantsi, kunye nokukhutshwa okuphantsi kunye nokulungelelaniswa komthamo wokuvelisa kufuneka kukhethwe. Ukusebenzisa inkqubo yokuxuba eqhelekileyo, i-peak current yomphathi wokuxuba malunga ne-90A. Ukusebenzisa inkqubo yokuxuba amatye e-asphalt, i-peak current ye-hosting host i-70A kuphela. Ngokuthelekisa, kufunyenwe ukuba inkqubo entsha inokunciphisa i-peak current yomphathi wokuxuba malunga ne-30% kunye nokunciphisa umjikelezo wokuxuba, ngaloo ndlela ukunciphisa ukusetyenziswa kwamandla kwinkqubo yokuvelisa izityalo ze-asphal.
