Njengendlela ebalulekileyo yezothutho kuhambo lwethu lwemihla ngemihla, oohola bendlela baya bexatyiswa ngakumbi kumgangatho wabo. Ukuqinisekisa ukusetyenziswa kwazo okuqhelekileyo kudlala indima ebalulekileyo ekugcineni ukhuseleko ezindleleni. Kwitekhnoloji yogcino lwanamhlanje, iteknoloji yokukhusela ibaluleke kakhulu. Ukuze kuncitshiswe iintlekele zoohola bendlela, ukugcinwa kohola bendlela ngaphambi kokuba kwenzeke iintlekele kuya kuphucula umgangatho kunye nobomi benkonzo yoohola bendlela. Inqaku eliphambili lokugcinwa lilele kwisizathu sesi sifo. Oko kubizwa ngokuba "kukumisela iyeza elichanekileyo" kunokuba nefuthe elingcono.
Ipavumente yeasphalt ngoku yeyona ndlela iphambili yendlela yendlela kwilizwe lam. Ukusetyenziswa kwayo okubanzi kungenxa yeenzuzo zayo zokulala, ukuxhathisa ukunxiba, ukwakhiwa okufanelekileyo, kunye nokugcinwa okulula okulandelayo. Yonke into inamacala amabini, kwaye i-asphalt pavement ineziphene zayo. Izifo ziya kwenzeka ngenxa yobushushu obugqithisileyo. Umzekelo, amaqondo obushushu aphezulu ehlotyeni aya kubangela ukuthamba, kwaye amaqondo obushushu aphantsi ebusika aya kubangela iintanda. Ngenxa yokusilela kwayo, iindlela zokuhamba zendlela zihlala zinengxaki yezi zifo zilandelayo:

Iintanda zoLongitudinal: Iintanda zenzeke kuhola wendlela ngenxa yokungalingani kokusasazwa komhlaba kunye noxinzelelo olungalinganiyo. Ngokusisiseko ziintanda zelongitudinal. Kukho izizathu ezibini: i-roadbed ngokwayo, ukuhlaliswa okungalinganiyo kwendlela, ekhokelela ekuveleni kweentanda ze-longitudinal; iintambo ze-longitudinal ziphathwa ngendlela engafanelekanga ngexesha le-asphalt paving process, kunye nomthwalo wesithuthi kunye nefuthe lemozulu ngexesha lokusetyenziswa likhokelela ekuveleni kweentanda.
Ukuqhekeka okuguquguqukayo: Ikhonkrithi ye-asphalt iyacutheka okanye ihlalise ngokwahlukileyo phantsi kwesenzo sokwahluka kobushushu bangaphakathi, okubangela ukuqhekeka kwendlela. Zombini iintanda ze-longitudinal kunye nee-longitudinal cracks zizifo zohlobo lokuqhekeka. Kukho iintlobo ezininzi zeentanda ezinqamlezileyo. Ezona ziqhelekileyo ziquka ukuqhekeka kokuhlaliswa okwahlukileyo, ukuqhekeka okunxulumene nomthwalo kunye neengqimba ezisisiseko eziqinileyo. Ukuqhekeka okubonakalayo
Ukudinwa kukuqhekeka: Impembelelo yendawo yangaphandle ibangela umlinganiselo omkhulu wokwakheka kweentanda zokudinwa. Uhola wendlela ohamba ngeenyawo ubekwa elangeni ixesha elide ehlotyeni. Ubushushu obuqhubekayo obuphezulu buya kuthambisa ipavumente ye-asphalt yekhonkrithi. Ngexesha leemvula, amanzi emvula aya kukhukuliseka aze agqobhoze, nto leyo eya kukhawulezisa ukuthotywa komgangatho wepavumente ye-asphalt yekhonkrithi. Umthwalo wesithuthi, ukuthotywa kwendlela kuya kuqinisa, umthamo wokuqala wokuthwala umgca wendlela uya kuncitshiswa, kwaye ukujikeleza kwexesha elide kuya kubangela ukuchithwa kokukhathala.
Ukuqhekeka okubonakalayo: ikakhulu kunxulumene ne-extrusion yangaphakathi kunye ne-shrinkage ye-pavement. Amacandelo amathathu omgwaqo omkhulu, i-roadbed, i-base layer kunye ne-surface layer, ibekwe ngokulandelelana ukusuka phezulu ukuya phezulu. Uluhlu lwesiseko luphakathi kwendlela kunye nomgangatho ophezulu. I-Extrusion kunye ne-shrinkage ye-base layer iya kubangela ukuqhekeka. Ukuqhekeka kwinqanaba lesiseko kuya kubonakaliswa kwi-roadbed layer kunye ne-surface layer, kunye nezinye iindawo zangaphandle. Ukuchaphazeleka, iintanda ezikhanyayo zivela.
Umonakalo weRut: Zintathu iindidi zomonakalo werut: iiruti zokungazinzi, iiruti zesakhiwo kunye neruts. I-rutting deformation ibangelwa ikakhulu kwiipropati zezinto ze-asphalt ngokwayo. Kwiqondo lokushisa eliphezulu, i-asphalt iba yinto engazinzile, kwaye isenzo esiqhubekayo sezithuthi kwi-asphalt pavement kubangela ukuguqulwa kwexesha elide kwi-pavement. Izinto ze-asphalt zihamba ngokuhamba kwe-viscous phantsi koxinzelelo, kubangela i-ruts. Nayiphi na ifom iya kuba nefuthe kumphezulu wendlela.
Ukukhukula kwe-oyile: Uyilo lomxube we-asphalt kunye nemveliso iqulethe i-asphalt eninzi, ukuxuba akulawulwa kakuhle, kwaye i-asphalt ngokwayo inozinzo olubi. Xa ubeka i-asphalt pavement, isixa se-oyile encangathi encangathi ayilawulwa kakuhle kwaye amanzi emvula ayangena, okukhokelela kwizikhukhula ze-oyile kwinqanaba lamva. Kwimozulu eshushu, i-asphalt ihamba ngokuthe ngcembe ukusuka ezantsi kunye nenxalenye esezantsi yomxube ukuya kumaleko angaphezulu, ibangela ukuba i-asphalt iqokelele. Ukongeza, amanzi emvula abangela ukuba i-asphalt iqhube kwaye ihambe, kwaye i-asphalt eninzi iqokelelana kwindlela, inciphisa amandla e-anti-skid. Sisifo sendlela enye esingenakuguqulwa.
