Asphalt e kopanyang limela le bapala karolo ea bohlokoahali ho kahong ea litsela tsa ka. Boleng ba lisebelisoa tsena bo ama tsoelo-pele le boleng ba morero. Sesebelisoa sena ke sesebelisoa sa ho hlahisa konkreite ea asphalt ka melemo e mengata, empa liphoso tse ling li ntse li tla khotsofatsoa nakong ea ts'ebeliso. Sengoliloeng sena se tla hlalosa hakhutšoanyane le mathata a tloaelehileng a asphalt limela le tharollo tse tsamaellanang.

E 'ngoe ea liphoso tse tloaelehileng tsa lijalo tsa asphalt, ke ho hloleha ha sesebelisoa sa ho fepa thepa e jang. Ka kakaretso, ho hloleha hoa ho fepa ka lisebelisoa tse batang ho bolela bothata ba ho koaloa ha lebaba le thata la metsi. The main reason for this phenomenon is that there are too few raw materials in the cold material hopper, which makes the loader have too much impact on the belt when feeding, so the cold material feeding device will stop working due to overload. Tharollo ea bothata bona ke ho netefatsa hore palo ea thepa e tala e bolokiloeng sesebelisoa sa ho fepa e lekane.
Ho sitoa ha motsoako oa konkreiti oa semela se kopanyang le ho kopanya hape ho e 'ngoe ea mathata a tloaelehileng. Ka kakaretso, e bakoa ke mosebetsi o fetelletseng o bakang lerata le sa tloaelehang mochining. Tharollo ea bothata bona ke ho lekola khafetsa ho netefatsa hore na ho na le bothata. Haeba ho na le, boithabiso bo tsitsitseng bo hloka ho nkeloa sebaka.
