Mbere yo gutangira inyanja ya srerry, ugomba kwitegura kugenzura ubwiza bwibikoresho bya kaleya mbere yo kubaka. Imwe mu ngingo zingenzi ni ukugenzura niba ibikubiye byo guhinga Asfalt bishobora kuba byujuje ibisabwa, kandi imvange igomba kandi kuzuza ibisabwa. Nyuma yo kwemeza ibipimo ngenderwaho, reba niba umuhanda wubatswe ugomba kwuma, udafite imyanda, amazi, igorofa, nibindi.

Reba neza niba amavuta ya moteri yageze ku mubare runaka; Niba impinduro ya buto y'amashanyarazi itandukanye yizewe; Niba hari amazi ahagije mu kigega cy'amazi; Niba imbaho ​​zibice bitandukanye byumuvurako usebanya arimbaraga; Urunigi rukeneye kuminjakurwa n'amavuta akwiye kugira ngo ayo mavuta amenye; Niba umukandara wa convoye uri mumwanya ukwiye; Niba ingingo ya hydraulic ihujwe, niba amavuta ya hydraulic ari murwego rusanzwe rwo gukoresha; Niba pompe y'amazi na pompe ya asfalt ikora bisanzwe.
Mugihe utangiye kashe ya slurry, tangira moteri ya mazutu hanyuma ushire agasanduku ka paver mumwanya wakazi, hanyuma uhindure ubunini bwa pang. Koresha amazi kugirango utoshe agasanduku k'ibiti. Nyuma yo gutangira moteri ya hydraulic hanyuma uhindure uyobora, koresha Diesel kugirango utere agitator na pauda agasanduku kugirango ugabanye adsion. Umusazi usebanya akanda pedal clutch nkuru, yihutisha imitwaro itatu, kandi yihutisha guhita akingura amazi ya asfalt. Noneho noneho arekura buhoro buhoro pedal nkuru, hanyuma ushire imitako yose yimashini yose mugikorwa gukangura imvange yujuje ibyangombwa.
Seno Hofeer ni isosiyete ihindagurika mu gutanga ibisobanuro bitandukanye z'umuhanda uzwi cyane asfalt na asfalt ashyushye, abasemuzi b'abanyabwenge, bakwirakwiza asfalt, bakwirakwiza asfalt. Gutandukana byujuje ibisabwa byose mumishinga yo kubaka umuhanda.
