Txhawm rau kom ntseeg tau qhov sib tov zoo ntawm asphalt, tus nqi ntawm ntau yam khoom siv raw yuav tsum tau tswj, thiab lub ntsuas ntsuas yog qhov tseem ceeb. Tab sis dab tsi koj yuav tsum tau them sai sai rau thaum ntsuas asphalt tov khoom? Cia peb saib.
Thaum cov cuab yeej sib xyaw asphalt ua haujlwm metering, kev txav ntawm txhua lub qhov rooj tawm yuav tsum tau hloov pauv, txawm tias nws qhib lossis kaw; Nyob rau tib lub sijhawm, qhov smoothness ntawm txhua qhov tso tawm qhov chaw nres nkoj yuav tsum tau ua kom ntseeg tau, thiab yuav tsum tsis muaj sediment, thiaj li ua kom cov khoom tuaj yeem ntws sai thiab sib npaug thaum ntsuas.
Tom qab kev ntsuas kev ua haujlwm tiav, nws tsis tuaj yeem tshwm sim ntawm cov khoom siv kom tsis txhob cuam tshuam ntawm lub thoob vim cov khoom txawv teb chaws. Thaum lub sij hawm hnyav txheej txheem, txhua yam khoom cia siab rau qhov sib thooj hnyav sensor ua haujlwm, yog li lub zog yuav tsum tsis tu ncua los ua kom lub sensor rhiab heev.
