Numuhanda wingenzi wurugendo rwacu rwa buri munsi, umuhanda munini uragenda uhabwa agaciro kubwiza bwabo. Kugenzura niba imikoreshereze yabo isanzwe igira uruhare runini mukubungabunga umutekano wumuhanda. Muri tekinoroji yo kubungabunga uyumunsi, tekinoroji yo kubungabunga ibidukikije ni ngombwa cyane. Mu rwego rwo kugabanya ibiza byo mu muhanda, kubungabunga imihanda minini mbere y’ibiza bizaba bizamura ubuzima n’imirimo y’imihanda. Ingingo y'ingenzi yo kubungabunga iri mu nyirabayazana w'indwara. Ibyo bita "kwandika imiti ikwiye" birashobora kugira ingaruka nziza.
Umuhanda wa asfalt ubu nuburyo nyamukuru bwo gutunganya umuhanda munini mugihugu cyanjye. Gukoresha kwagutse kwinshi biterwa nibyiza byo kuringaniza, kwambara birwanya, kubaka byoroshye, no kubitaho byoroshye. Ibintu byose bifite impande ebyiri, na pavement ya asfalt nayo ifite amakosa yayo. Indwara zizabaho kubera ubushyuhe bukabije. Kurugero, ubushyuhe bwinshi mugihe cyizuba bizatera koroshya, nubushyuhe buke mugihe cyimbeho bizatera ibice. Bitewe ninenge zayo, kaburimbo nyabagendwa ikunze kurwara indwara zikurikira:

Ibice birebire: Ibice bibaho mumihanda nyabagendwa kubera isaranganya ry'ubutaka butaringaniye hamwe no guhangayika kutaringaniye. Ahanini ni ibice birebire. Hariho impamvu zibiri: umuhanda wumuhanda ubwawo, gutuza kuringaniza umuhanda, biganisha kumyanya ndende; ingingo ndende zifatwa nabi mugihe cyo gutunganya asfalt, kandi umutwaro wikinyabiziga hamwe n’imihindagurikire y’ikirere mu gihe cyo gukoresha bituma habaho gucika.
Guhinduranya ibice: Asifalt ya beto iragabanuka cyangwa igatandukana muburyo butandukanye nubushyuhe bwimbere bwimbere, bigatera kaburimbo. Byombi birebire kandi birebire ni indwara zo mu bwoko. Hariho ubwoko bwinshi bwimyenda ihindagurika. Ibisanzwe birimo gutandukanya gutandukanijwe, imitwaro ijyanye nu mutwaro hamwe nuburyo bukomeye. ibice byerekana
Umunaniro ucika: Ingaruka yibidukikije byo hanze bigira uruhare runini rwo gushiraho umunaniro. Umuhanda nyabagendwa uhura nizuba igihe kinini mugihe cyizuba. Ubushyuhe bwo hejuru buhoraho buzoroshya asifalt ya kaburimbo. Mugihe cyimvura, amazi yimvura azakaraba kandi yinjire, bizihutisha kwangirika kwubwiza bwa kaburimbo ya asfalt. Imizigo yimodoka, koroshya ubuso bwumuhanda biziyongera, ubushobozi bwambere bwo gutwara hejuru yumuhanda bizagabanuka, kandi kuzenguruka igihe kirekire bizatera umunaniro.
Ibice byerekana: ahanini bifitanye isano no gusohora imbere no kugabanuka kwa kaburimbo. Ibice bitatu byumuhanda, umuhanda, umuhanda shingiro hamwe nubuso bwubuso, byashyizwe kumurongo kuva hejuru kugeza hasi. Igice fatizo kiri hagati yumuhanda nu gice cyo hejuru. Gukuramo no kugabanuka kurwego rwibanze bizatera ibice. Ibice biri murwego rwibanze bizagaragarira kumurongo wumuhanda no hejuru yubuso, kimwe nubundi buso bwo hanze. Ingaruka, zigaragaza ibice bigaragara.
Kwangirika kwimbuto: Hariho ubwoko butatu bwangirika bwurutoki: urusenda rudahungabana, ibiti byubatswe hamwe nigituba. Guhindura imitekerereze biterwa ahanini nimiterere yibikoresho bya asfalt ubwayo. Ku bushyuhe bwinshi, asfalt iba idahindagurika, kandi ibikorwa bikomeza byimodoka kumuhanda wa asfalt bitera ihinduka ryigihe kirekire rya kaburimbo. Ibikoresho bya asfalt bigenda bitembera neza mukibazo, bigatera urusenda. Imiterere yombi izagira ingaruka hejuru yumuhanda.
Umwuzure wamavuta: Igishushanyo mbonera cya asfalt nigikorwa kirimo asfalt nyinshi, kuvanga ntabwo bigenzurwa neza, kandi asfalt ubwayo ifite umutekano muke. Iyo ushyizeho kaburimbo ya asfalt, ubwinshi bwamavuta yumutambiko ntagenzurwa neza kandi amazi yimvura arinjira, bigatuma amavuta yuzura mugihe cyanyuma. Mu gihe cy'ubushyuhe, asfalt igenda gahoro gahoro kuva hepfo no hepfo yuruvange kugeza kurwego rwo hejuru, bigatuma asfalt yegeranya. Byongeye kandi, amazi yimvura atera asfalt guhora yikuramo kandi ikagenda, kandi asfalt ikabije irundanya hejuru yumuhanda, bikagabanya ubushobozi bwumuhanda wo kurwanya skid. Nindwara idasubirwaho inzira imwe.
