The bidirectional flat compactor bụ tumadi eji na compaction arụmọrụ, karịsịa maka compaction arụmọrụ na warara ọwara, na ike ga-eji maka compaction nke engineering ntọala na asphalt pavement. O nwekwara njirimara ụfọdụ, nke bụ:
(1) Ọ dị mfe ịmalite na ịrụ ọrụ dị nro;
(2) Efere ala nke kọmpat dị larịị bụ nke manganese alloy steel ma ọ bụ ihe ductile iron, nke nwere nguzogide dị mma;
(3) E jirila plastik fesa elu ya, nke nwere ọdịdị magnesium na-egbuke egbuke, ọ pụkwara igbochi nchara na corrosion.
Ụkpụrụ na-arụ ọrụ nke compactor flat-bidirectional bụ nke a: injin dị na kọmpat dị larịị na-eme ka eccentric na-emepụta vibration site na njigide na pulley, na efere ala na eccentric na-edozi ọnụ. Iji gbanwee ntụziaka nke ịma jijiji, enwere ike ime ya site n'ịtụgharị ngọngọ eccentric. Ọzọkwa, iji nweta ịma jijiji na-aga n'ihu, ịma jijiji nọ n'ebe, na ịma jijiji azụ.
