Gufunga ibicu nuburyo bwo gufata neza umuhanda hamwe nuburyo bwinshi bwo gusaba. Ahanini bikoreshwa mumihanda ifite ihazabu yoroheje cyangwa igereranije igihombo cyangwa ibikoresho bidakabije. Kurugero, iyo pavement ya asfalt irekuye, igicu cyikimenyetso kirashobora gukemura ikibazo; nkubuso bwuruvange rwa asfalt rwinshi rwubusa hejuru yubusaza bwa pockmarked, hejuru yikimenyetso cya kaburimbo, hejuru yuruvange rwa asfalt ruvanze, nibindi. Byerekeza cyane cyane kukuba umuhanda watangiye kwerekana umunaniro muto. hamwe nigihombo cyiza, kandi amazi yacyo yariyongereye. Amazi ya kaburimbo azinjira mu mvange ya asfalt binyuze mu gucamo cyangwa kwangirika kwinshi, bitera gucikamo ibice, kumeneka, hamwe na Potholes nibindi bihe bya kaburimbo aho imiterere ya kaburimbo ikora neza.
Imashini yo gufata neza igihu: Igice kinini cya asfalt gisaza vuba mumyaka 2-4 yambere ikoreshwa, bigatuma hafi 1CM ya asfalt hejuru yumuhanda ihinduka gucika intege, bigatera gucika kare, kurekura nibindi byangiza hejuru yumuhanda, namazi yo hambere kwangirika hejuru yumuhanda. Indwara, nuko imyaka 2 kugeza kuri 4 nyuma ya asfalt pavement ifunguye mumodoka nigihe cyo gukomeza kashe ya gihu. Bikwiye kugenwa byumwihariko hashingiwe ku iperereza ryindwara zisanzwe zubatswe nimirimo ya pavement, indangagaciro ya pavement PCI, indangagaciro mpuzamahanga ya IRI, ubujyakuzimu bwubatswe, imiterere yambara nandi moko.
Igikorwa cyo gufunga igihu:
(1) Ingaruka zidafite amazi, zishobora kugabanya neza kwangirika kwamazi hejuru yumuhanda;
.

.
(5) Mu buryo bwikora gukiza ibice biri munsi ya 0.3MM;
(6) Igiciro cyo kubaka ni gito kandi ubuzima bwumuhanda burashobora kongerwa.
Uburyo bwo kubaka nuburyo bwo kwirinda:
