Dukurikije ubushakashatsi bwakozwe mbere n’ubushakashatsi bwakozwe, umurima wa asfalt uterwa no guhindagurika, kwinjizwa, okiside, hamwe n’amafoto ya fotokimike ya kaburimbo, kandi igipimo cya asfalt kigabanuka cyane mugihe cyambere cyo gusaza, bikaviramo umuhanda woroshye kandi woroshye. Hamwe no gutwarwa nisuri ya asfalt, pavement ishaje igereranije irerekana ibiyirimo. Umuhanda wa asfalt winjira mugihe cyo gusaza kubera guhora ushwanyagurika hamwe nikirere, aho amabuye ahura nuduce duto kuri pavement.

Mugihe cyo gusaza, guhindagurika nimbaraga zuburyo bwa kaburimbo bigabanuka. Amaherezo, umuhanda munini wa kaburimbo ubaho muburyo bwo gutondekanya umurongo, gucamo alligator, ibinogo no gutemba. Iyi nzira igabanya cyane ubukonje nubukonje, byongera guhindagurika no guhinduka, kandi bigatuma asfalt idakunda gucika no kwangirika.
Bitandukanye na kashe ya kera yashaje, ikoreshwa rimwe ryikizamini cyo kuvugurura asfalt cyinjira muri kaburimbo kugirango ugarure kandi usimbuze igitereko na asfalt yatakaye kubera ubuso bwa okiside munsi ya asifalt ikingiwe. Irafunga kandi ikarinda kaburimbo amazi, urumuri rwizuba hamwe n’imyanda ihumanya, bigatera imbere cyane kuramba, ubuzima no kugabanya ubwiza bwa asfalt. Abakora ivanga rya asfalt bakwibutsa ko kubungabunga neza arirwo rufunguzo rwo kurinda asfalt kubintu byo hanze byambara.
