[1] Zvirwere zvakajairika zveasphalt pavement
Kune marudzi mapfumbamwe ekukuvadzwa kwekutanga kweasphalt pavement: ruts, makatsemuka, uye makomba. Zvirwere izvi zvakajairika uye zvakakomba, uye ndeimwe yematambudziko akajairika emapurojekiti emigwagwa.
1.1 Rut
Ruts inoreva migero yakareba yakaita sebhandi inogadzirwa padivi pemavhiri emigwagwa pamusoro pemugwagwa, ine hudzamu hunodarika 1.5cm. Rutting igororo rakaumbwa nebhandi rinoumbwa nekuunganidzwa kwechigarire deformation munzira yemugwagwa pasi pemitoro inodzokororwa yekutyaira. Rutting inoderedza kunaka kwenzira. Kana matinji asvika pahumwe hudzamu, nekuda kwekuungana kwemvura mumaruts, mota dzinowanzotsvedza uye kukonzera tsaona dzemotokari. Rutting inonyanya kukonzerwa nekugadzirwa kusina musoro uye kuwandisa kwemota.
1.2 Mitswe
Kune matatu makuru maitiro ekutsemuka: longitudinal cracks, transverse cracks uye network cracks. Kutsemuka kunoitika muasphalt pavement, zvichikonzera kuyerera kwemvura uye kukuvadza nzvimbo yepamusoro uye base layer.
1.3 Gomba uye groove
Makomba chirwere chinowanzoitika cheasphalt pavement, izvo zvinoreva kukuvadzwa kwegwara mumakomba ane kudzika kunodarika 2cm uye nzvimbo inopfuura 0.04㎡. Makomba anoumbwa zvakanyanya kana kugadzirwa kwemotokari kana mafuta emotokari achipinda munzira. Kusvibiswa kunoita kuti musanganiswa weasphalt usununguke, uye makomba anoumbwa zvishoma nezvishoma nekutyaira nekukunguruka.
1.4 Peeling
Asphalt pavement peeling (asphalt pavement peeling) zvinoreva kusvuura pasi penzvimbo yakarongwa, ine nzvimbo inopfuura 0.1 square metres. Chikonzero chikuru chekupenengura asphalt pavement kukuvara kwemvura.
1.5 yakasununguka
Kusununguka kweasphalt pavement zvinoreva kurasikirwa kwesimba rekubatanidza bhainda repavhu uye kusunungurwa kweaggregates, nenzvimbo inopfuura 0.1 square metres.

[2] Matanho ekuchengetedza ezvirwere zvakajairika zveasphalt pavement
Kune zvirwere zvinoitika mukutanga kweasphalt pavement, tinofanira kuita basa rekugadzirisa nenguva, kuitira kuti tideredze kukanganisa kwechirwere pakuchengetedza kwekutyaira kweasphalt pavement.
2.1 Kugadziriswa kwemarutsi
Nzira huru dzekugadzirisa asphalt road ruts ndedzinotevera:
2.1.1 Kana nzvimbo yemugwagwa yakasvibiswa nekuda kwekufamba kwemotokari. Nzvimbo dzakarukwa dzinofanirwa kubviswa nekucheka kana kugaya, uye ipapo iyo asphalt yepamusoro inofanira kudzoserwa. Wobva washandisa asphalt mastic gravel musanganiswa (SMA) kana SBS yakagadziridzwa asphalt imwe musanganiswa, kana polyethylene yakagadziridzwa asphalt musanganiswa kugadzirisa ruts.
2.1.2 Kana nzira yemugwagwa ikasundidzirwa nechekumberi uye ikaita lateral corrugated ruts, kana yakadzikama, iyo inobuda kunze inogona kutemwa, uye zvikamu zvechigero zvinogona kupfapfaidzwa kana kupendwa neasphalt yakasungwa uye kuzadzwa neasphalt musanganiswa, kuenzanisa, uye. compacted.
2.1.3 Kana rutting ichikonzerwa nekuderera kwechikamu chehwaro nekuda kwekusasimba kwesimba uye kusagadzikana kwemvura kwepasi, base layer inofanira kutanga yagadziriswa. Bvisa zvachose chikamu chepamusoro uye chigadziko chepamusoro
2.2 Kugadziriswa kwepakatsemuka
Mushure mekuputika kweasphalt pavement kuitika, kana zvose kana zviduku zviduku zvinogona kuporeswa munguva yekushisa kwepamusoro, hapana kurapwa kunodiwa. Kana paine akatsemuka madiki asingagone kuporeswa mukati memwaka wekushisa kwepamusoro, anofanirwa kugadziriswa nenguva kuti adzore kuwedzera kwekuwedzera kwepakatsemuka, kudzivirira kukuvara kwekutanga kwegwagwa, uye kuvandudza kugona kwekushandisa mugwagwa mukuru. Saizvozvo, kana uchigadzirisa makatsemuka mu asphalt pavement, yakasimba maitiro mashandiro uye zvakatemwa zvinodiwa zvinofanirwa kuteverwa.
2.2.1 Oiri yekuzadza nzira yekugadzirisa. Munguva yechando, chenesa zvakadzika uye zvakachinjika zvakatsemuka, shandisa liquefied gasi kupisa madziro anotsemuka kusvika kune viscous state, wobva wapfapfaidza asphalt kana asphalt dhaka (emulsified asphalt inofanira kupfapfaidzwa mumwaka wakadzika-tembiricha uye hunyoro) mumitswe, wobva wapararira. zvakaenzana Zvidzivirire nehupamhi hwematombo akaoma akachena machipisi kana jecha rakaoma re 2 kusvika ku5 mm, uye pakupedzisira shandisa roller chiedza kupwanya mineral materials. Kana iri kuputika kuduku, kunofanira kuwedzerwa mberi ne disc disc milling cutter, uye yozogadziriswa maererano nenzira iri pamusoro apa, uye zvishoma zvishoma zveasphalt zvine zvishoma zvishoma zvinofanira kushandiswa pamwe chete nekuputika.
2.2.2 Gadzirisa asphalt pavement yakatsemuka. Panguva yekuvaka, tanga wabvisa mitswe yakare kuti uite mukova wakaita V; zvino shandisa air compressor kuti ivhuvhute kunze kwezvikamu zvakasununguka uye guruva uye mamwe marara mukati uye kumativi ose eV-shaped groove, uye zvino shandisa extrusion pfuti kusanganisa zvakaenzana zvakasanganiswa Zvinhu zvekugadzirisa zvinodururwa mukuputika kuti zvizadze. Mushure mekunge zvinhu zvekugadzirisa zvasimba, ichave yakavhurika kune traffic mune rinenge zuva. Mukuwedzera, kana pane kuputika kwakakomba nekuda kwekusakwana kwesimba renheyo yevhu kana chigadziko chepamusoro kana slurry yemugwagwa, nheyo yepasi inofanira kurapwa kutanga uye ipapo iyo yepamusoro inofanira kugadziriswa zvakare.
2.3 Kuchengeta makomba
2.3.1 Nzira yekuchengeta kana chigadziko chepamusoro pemugwagwa chiripo uye chikamu chepamusoro chete chine makomba. Zvinoenderana nemusimboti we "round hole square repair", dhizainira iyo pothole kugadzirisa parallel kana perpendicular kumutsara wepakati wemugwagwa. Ita zvinoenderana nerectangle kana sikweya. Cheka pothole kune chikamu chakagadzikana. Shandisa air compressor kuchenesa pasi pe groove uye groove. Chenesa guruva uye zvikamu zvakasununguka zvemadziro, uye wozosasa tsvina yakasungwa yeasphalt pazasi kwakachena kwetangi; tangi rusvingo inobva yazadzwa neyakagadzirirwa asphalt musanganiswa. Wobva waikungurusa neruvoko rwemaoko, uchiita shuwa kuti iyo compaction force inobata zvakananga pamusanganiswa weasphalt wakagadzirwa. Nenzira iyi, kuputika, kuputika, nezvimwewo hazvizoitiki.
2.3.1 Gadzirisa nenzira inopisa yekubatisa. Motokari yekugadzira inopisa inoshandiswa kupisa mugwagwa mugomba nendiro yekudziya, kusunungura kupisa uye kupfava pavement layer, kupfapfaidza emulsified asphalt, wedzera musanganiswa weasphalt mutsva, wobva wabvongodza uye gadzira, uye woibatanidza nemugwagwa.
2.3.3 Kana iyo base layer yakakuvadzwa nekuda kwekushaikwa kwesimba renzvimbo uye makomba akaumbwa, iyo yepamusoro layer uye base layer inofanira kucherwa zvachose.
2.4 Kugadziriswa kwekupepeta
2.4.1 Pamusana pekusabatana kwakashata pakati peasphalt surface layer uye yepamusoro sealing layer, kana kusvuura kunokonzerwa nekusava nekugadzirisa kwekutanga, zvikamu zvakasvunurwa uye zvakasununguka zvinofanira kubviswa, uye ipapo chikamu chekuvhara chepamusoro chinofanira kuvandudzwa. Huwandu hweasphalt hunoshandiswa muvharo yekuisa chisimbiso hunofanirwa kunge huri Uye saizi yehukuru hwemamineral zvinhu zvinofanirwa kuenderana nehupamhi hwechisimbiso layer.
2.4.2 Kana kusvuura kukaitika pakati pematanho epamusoro easphalt, kusvuura uye zvikamu zvakasununguka zvinofanira kubviswa, nzvimbo yepasi yeasphalt inofanira kupendwa neasphalt yakasungwa, uye asphalt layer inofanira kuitwa zvakare.
2.4.3 Kana kusvuura kukaitika nekuda kwekusabatana kwakashata pakati pedenga repamusoro nenheyo yepasi, kusvuura uye kusununguka kunofanira kutanga kubviswa uye chikonzero chekusabatana kwakashata chinofanira kuongororwa.
2.5 Kuchengetedza kwakasununguka
2.5.1 Kana paine kushomeka kwegomba nekuda kwekurasikirwa kwezvinhu zvinokonzeresa, kana asphalt pamusoro peturu isina kupera mafuta, yakakodzera caulking zvinhu zvinogona kusaswa mumwaka wekushisa kwakanyanya uye kutsvairwa zvakaenzana nemutsvairo kuzadza maburi mudombo. nezvinhu zvinokonzeresa.
2.5.2 Panzvimbo dzakakura dzenzvimbo dzakaiswa pockmarked, pfapfaidza asphalt ine kusimba kwepamusoro uye mwaya zvinhu zvekukasira nemasaizi akakodzera. Iyo caulking zvinhu zviri pakati peiyo pockmarked nzvimbo inofanirwa kukora zvishoma, uye iyo yakatenderedza interface ine yepakutanga nzira yemugwagwa inofanira kunge yakatetepa zvishoma uye yakanyatso kuumbwa. Uye yakakungurutswa kuita chimiro.
2.5.3 Nzvimbo yemugwagwa haina kusimba nekuda kwekusanamatira zvakanaka pakati peasphalt nematombo ane acidic. Zvikamu zvese zvakasununguka zvinofanirwa kucherwa kunze uye ipapo iyo yepamusoro layer inofanira kugadzirwazve. Matombo ane acidic haafanirwe kushandiswa kana uchigadzirazve mineral zvinhu.
