2.2 Ndozi nke mgbape
Mgbe pavement asphalt gachara, ọ bụrụ na enwere ike gwọọ ihe niile ma ọ bụ ọtụtụ n'ime obere mgbape n'oge oke okpomọkụ, ọ dịghị ọgwụgwọ achọrọ. Ọ bụrụ na enwere obere mgbawa na-enweghị ike ịgwọta n'oge okpomọkụ dị elu, a ghaghị imezi ha n'oge iji chịkwaa mgbasawanye nke mgbawa ahụ, gbochie n'oge na-emebi pavement, ma melite arụmọrụ nke iji okporo ụzọ. N'otu aka ahụ, mgbe ị na-arụzi mgbape na pavement asphalt, a ghaghị ịgbaso usoro ọrụ siri ike na nkọwa nkọwa.
2.2.1 Usoro mmezi ndochi mmanụ. N'oge oyi, hichaa mgbape kwụ ọtọ na nke kwụ ọtọ, jiri gas na-ekpo ọkụ mee ka mgbidi mgbawa ahụ kpoo ọkụ na steeti viscous, wee fesaa asphalt ma ọ bụ ngwa agha asphalt (emulsified asphalt kwesịrị ịgbasa na obere okpomọkụ na oge iru mmiri) n'ime mgbawa ahụ, wee gbasaa.
