Imishini yezitshalo yokuxuba i-asphalt ingakhiqiza ingxube ye-asphalt, ingxube ye-asphalt eshintshiwe, kanye nengxube ye-asphalt enemibala, ehlangabezana ngokugcwele nezidingo zokwakha imigwaqo emikhulu, imigwaqo emikhulu, imigwaqo kamasipala, izikhumulo zezindiza, amachweba, njll. Ngenxa yesakhiwo sayo esiphelele, ukulinganisa okulungile, ukulinganisa okuphezulu ukunemba, ikhwalithi enhle yezinto eziqediwe, nokulawula okulula, kuyamukelwa kabanzi kumaphrojekthi we-asphalt pavement, ikakhulukazi amaphrojekthi womgwaqo omkhulu, kodwa ngezinye izikhathi ukukhubeka kwenzeka ngesikhathi somsebenzi, ngakho-ke yini okufanele siyenze uma lesi simo senzeke?

Ngomxube we-asphalt wesikrini esidlidlizayo: sebenzisa uhambo olulodwa ngaphandle komthwalo, bese uqala kabusha uhambo futhi. Ngemva kokushintsha i-thermal relay entsha, iphutha lisekhona. Hlola othintana naye, ukumelana kwe-motor, ukumelana ne-grounding kanye ne-voltage, njll, futhi azikho izinkinga ezitholakele; yehlisa ibhande lokudlulisela, qala isikrini esidlidlizayo, i-ammeter ikhombisa okujwayelekile, futhi ayikho inkinga ngokukhubeka imizuzu engama-30 ngaphandle kokusebenza komthwalo. Iphutha alikho engxenyeni kagesi. Ngemva kokufaka kabusha ibhande lokudlulisela, isikrini esidlidlizayo sitholwe sihlulwe kakhulu yi-eccentric block.
Nqamula i-eccentric block, qala isikrini esidlidlizayo, i-ammeter ibonisa iminyaka engu-15; imitha kazibuthe igxiliswe epuleti lebhokisi lesikrini elidlidlizayo, ukuphuma kwe-radial kuhlolwa ngokumaka i-shaft, futhi ukuphuma kwe-radial okuphezulu ngu-3.5 mm; i-ovality ephezulu yobubanzi obungaphakathi obuthwele yi-0.32 mm. Miselela i-abheri yesikrini esidlidlizayo, faka i-eccentric block, qala kabusha isikrini esidlidlizayo, futhi i-ammeter ikhombisa okwejwayelekile. Alusekho uhambo.
