Uku kugona kwekubatanidza kwakakosha pakuchengetedza nzvimbo dzakatsetseka uye dzakachengeteka dzemumugwagwa wepamusoro kwenguva yakareba sevhisi.
Bhitumini yemumugwagwa inokosheswawo nekushanduka kwayo. Migwagwa mikuru inoratidzwa nekusiyana kwetembiricha izvo zvinoita kuti zvinhu zviwedzere uye zvibvumirane. Bhitumini yemumugwagwa inobvumira mapavha kuti agadzirise kune aya mafambiro pasina kutadza kukuru kwechimiro. Nekuda kweizvozvo, migwagwa yakagadzirwa nepamusoro-soro bhitumeni yemugwagwa inoratidza kusimudzira kupikisa kuneta uye deformation.
Mukuwedzera, bhitumini yemugwagwa inobatsira pakudzivirira mvura. Nokugadzira chitubu chisingapindi mvura, bhitumini yomumugwagwa inobatsira kudzivirira mwando kuti usapinda mugwagwa, izvo zvinoderedza kukukurwa uye kurebesa upenyu hwomumugwagwa. Iri basa rekudzivirira rakakosha zvakanyanya munzvimbo dzinonaya mvura zhinji kana chando chechando.
Kuvakwa kwemigwagwa mikuru yemazuva ano kunotsamira pamagiredhi akanyatsosarudzwa ebhitumini yemugwagwa kuti aenderane nemitoro yemotokari uye nemamiriro ekunze.
