Misewu yayikulu yabweretsa mwayi kwambiri m'miyoyo ya anthu. Kukula kwapamwamba kwa makampani Rapem ndikosagwirizana ndi zida zapamwamba zapamwamba zapamwamba komanso zomangira zophatikizidwa bwino za phula. Kupanga kwa asphalt osinthidwa kumafuna ukadaulo wapamwamba kwambiri ndikupanga zida zapamwamba komanso zida zapamwamba. Njira yosavuta komanso yotheka kuyenda bwino ya zida za phula zosasinthika zimatha kukwaniritsa zotsatira za kukwaniritsidwa kwamphamvu, kupulumutsa mphamvu ndi kuwononga mphamvu. Magawo abwino kwambiri ophatikizidwa osinthika asphalt ayang'ana chidwi cha anthu. Kusintha kwa njira yosinthidwa phula losasinthika kumatha kuwunikira kusakhazikika kwa zida.

Pofuna kukonza mavuto wamba pokonza zomangira zophatikizira za masitedwe, kupanga kwa aspharation asphalted kumatsimikizidwa ndikupangidwanso, ndipo mphero za Emloid ndi Colloid ndizosintha. Kudzera pamayeso ndi nthawi yopanga, zimatsimikiziridwa kuti mavuto omwe ali pamwambawa atha kuthetsedwa kwathunthu.
Kusintha kwa njira ya njirayi kwasintha kwambiri pakupanga kwa asphalt osinthidwa. Cholinga chogwiritsa ntchito choyambirira kenako ndikupera ndikumachiritsa asphalt ndi sbs olimbikitsidwa koyamba kuchokera ku tambala yotupa musanalowe mchipinda cha mphero, kuchepetsa kugwiritsa ntchito mphamvu ya mphero, ndikusintha mphamvu ya Mphero. Kuyika mwanzeru ndi kuwonjezera kwa homogenizer yothamanga kumapereka chitsimikizo kuti musinthe bwino ntchito ndi kupanga kwa ma ephalsice osinthika.
