[1] Indwara zisanzwe za asfalt pavement
Hariho ubwoko icyenda bwo kwangirika hakiri kare kuri kaburimbo ya asfalt: inkeri, ibice, n'ibinogo. Izi ndwara zikunze kugaragara kandi zikomeye, kandi nikimwe mubibazo bisanzwe byumushinga wimihanda.
1.1 Rut
Imbuto bivuga umukandara muremure wumukandara ukorwa kumurongo wibiziga hejuru yumuhanda, hamwe nubujyakuzimu burenga 1.5cm. Rutting nigitereko kimeze nkigitereko cyakozwe no kwegeranya guhindagurika kumiterere yumuhanda munsi yimizigo myinshi. Kunyerera bigabanya ubworoherane bwumuhanda. Iyo urusenda rugeze ku burebure runaka, bitewe no kwegeranya amazi muri ruts, imodoka zirashobora kunyerera kandi zigatera impanuka zo mumuhanda. Kunyerera biterwa ahanini nigishushanyo kidafite ishingiro no kurenza urugero rwimodoka.
1.2 Ibice
Hariho uburyo butatu bwingenzi bwibice: ibice birebire, ibice byambukiranya imiyoboro. Ibisate biboneka muri kaburimbo ya asfalt, bigatera amazi kandi bikangiza igice cyo hejuru nubutaka bwibanze.
1.3 Urwobo
Ibinogo ni indwara ikunze kubaho ya asfalt pavement, bivuga kwangirika kwa kaburimbo mu myobo ifite ubujyakuzimu burenga 2cm hamwe nubuso bwa ?? burenga 0.04㎡. Ibinogo bikozwe cyane cyane iyo gusana ibinyabiziga cyangwa amavuta yimodoka yinjiye mumuhanda. Umwanda utera imvange ya asfalt irekura, kandi ibinogo bigenda bikorwa buhoro buhoro mu gutwara no kuzunguruka.
1.4
Gukuramo pavement ya asfalt bivuga gukuramo ibice hejuru yubuso bwa kaburimbo, hamwe nubuso bwa ?? burenga metero kare 0.1. Impamvu nyamukuru itera pevement ya asfalt ni kwangiza amazi.
1.5 irekuye
Kurekura kaburimbo ya asfalt bivuga gutakaza imbaraga zihuza za kaburimbo ya pavement no kurekura agregate, hamwe nubuso bwa metero zirenga 0.1.

[2] Ingamba zo gufata neza indwara zisanzwe za asfalt pavement
Ku ndwara zibaho mugihe cyambere cya pavement ya asfalt, tugomba gukora imirimo yo gusana mugihe, kugirango tugabanye ingaruka zindwara kumutekano wo gutwara ibinyabiziga bya asfalt.
2.1 Gusana ibiti
Uburyo nyamukuru bwo gusana umuhanda wa asfalt nuburyo bukurikira:
2.1.1 Niba umurongo unyuze hejuru kubera kugenda kwimodoka. Ubuso bubi bugomba gukurwaho mugukata cyangwa gusya, hanyuma ubuso bwa asfalt bugomba gusubukurwa. Noneho koresha asfalt mastique ivanze (SMA) cyangwa SBS yahinduwe asifalt imwe ivanze, cyangwa polyethylene yahinduwe asifalt ivanze kugirango usane inkeri.
2.1.2. yegeranye.
2.1.3. Kuraho burundu hejuru yubuso nuburinganire
2.2 Gusana ibice
Nyuma yo guturika kwa asfalt kabaye, niba ibice byose cyangwa byinshi byoroheje bishobora gukira mugihe cyubushyuhe bwinshi, nta muti usabwa. Niba hari uduce duto duto tudashobora gukira mugihe cyubushyuhe bwo hejuru, bigomba gusanwa mugihe kugirango bigenzure kurushaho kwaguka, gucika ibyangiritse hakiri kare, no kunoza imikorere yimikoreshereze yimihanda. Mu buryo nk'ubwo, mugihe cyo gusana ibice muri kaburimbo ya asfalt, hagomba gukurikizwa ibikorwa bikomeye kandi bisabwa.
2.2.1 Uburyo bwo kuzuza amavuta uburyo bwo gusana. Mu gihe c'itumba, sukura ibice bihagaritse kandi bitambitse, koresha gaze ya lisukari kugirango ushushe inkuta zacitse kugirango ugaragare neza, hanyuma utere minisiteri ya asfalt cyangwa asifalt (asifalt emulisifike igomba guterwa mugihe cy'ubushyuhe buke n'ibihe by'ubushuhe) mubice, hanyuma bigakwirakwira. kuringaniza Kurinda hamwe nigice cyumye cyumye cyumye cyangwa umucanga utubutse wa mm 2 kugeza kuri 5, hanyuma ukoreshe uruziga rworoshye kugirango umenagure ibikoresho byamabuye y'agaciro. Niba ari agace gato, kagomba kwagurwa hakiri kare hamwe no gukata disiki, hanyuma bigatunganywa hakurikijwe uburyo bwavuzwe haruguru, hanyuma umubare muto wa asfalt ufite ubudahangarwa buke ugomba gushyirwa kumurongo.
2.2.2 Gusana kaburimbo ya asfalt. Mugihe cyo kubaka, banza ukuremo ibice bishaje kugirango ube umuringoti wa V. hanyuma ukoreshe compressor yo mu kirere kugirango uturike ibice byangiritse hamwe n ivumbi hamwe nindi myanda mumashanyarazi ya V na hafi yayo, hanyuma ukoreshe imbunda yo kuvanga kugirango uvange kivanze neza Ibikoresho byo gusana bisukwa mumacenga kugirango wuzuze. Ibikoresho byo gusana bimaze gukomera, bizakingurwa mumodoka mugihe cyumunsi. Byongeye kandi, niba hari ibice bikomeye kubera imbaraga zidahagije zubutaka bwubutaka cyangwa igiti fatizo cyangwa umuhanda wumuhanda, igice cyibanze kigomba kubanza kuvurwa hanyuma igice cyo hejuru kigomba kongera gukorwa.
2.3 Kwita ku byobo
2.3.1 Uburyo bwo kwitaho mugihe igice cyibanze cyubuso bwumuhanda kidahwitse kandi igice cyo hejuru gusa gifite ibinogo. Ukurikije ihame ryo "gusana umwobo uzengurutswe", shushanya urucacagu rwo gusana ibinogo bisa cyangwa bitandukanijwe n'umurongo wo hagati w'umuhanda. Kora ukurikije urukiramende cyangwa kare. Kata ibinogo kugeza igice gihamye. Koresha compressor yumuyaga kugirango usukure hepfo yigitereko. Kwoza umukungugu n'ibice by'urukuta, hanyuma utere urwego ruto rwa asfalt ihambiriye munsi yisuku; urukuta rwa tank noneho rwuzuyemo ivangwa rya asfalt. Noneho uzenguruke ukoresheje uruziga rw'intoki, urebe neza ko imbaraga zo gukwega zikora ku buryo butaziguye ivanze rya asfalt. Hamwe nubu buryo, gucamo, gucamo, nibindi ntibizabaho.
2.3.1 Gusana nuburyo bushyushye. Imodoka yo gusana ishyushye ikoreshwa mu gushyushya hejuru yumuhanda mu cyobo hamwe nisahani yo gushyushya, kurekura pavement ishyushye kandi yoroshye, gutera asifalt emulisifike, kongeramo imvange nshya ya asfalt, hanyuma ukabyutsa na pave, hanyuma ukabishyira hamwe na roller.
2.3.3.
2.4 Gusana ibishishwa
2.4. Ingano ya asfalt ikoreshwa murwego rwo gufunga igomba kuba Kandi ingano yubunini bwibikoresho byubutare bigomba guterwa nubunini bwikimenyetso.
2.4.2.
2.4.3.
2.5 Kubungabunga neza
2.5.1. hamwe nibikoresho.
2.5. Ibikoresho bya kawkingi hagati yikibanza cyagenwe bigomba kuba binini cyane, kandi intera ikikije hamwe nubuso bwambere bwumuhanda igomba kuba yoroheje kandi ikozwe neza. Kandi yazungurutse mu buryo.
2.5.3 Ubuso bwumuhanda burarekuye kubera gufatana nabi hagati ya asfalt na acide. Ibice byose birekuye bigomba gucukurwa hanyuma igice cyo hejuru kigomba gusubirwamo. Amabuye ya acide ntagomba gukoreshwa mugihe hagaragaye ibikoresho byamabuye y'agaciro.
