Mwa njira zomangira misewu yayikulu yomwe yamalizidwa komanso yokonzedwa, yopitilira 95% ndi mipanda yolimba ya phula. Msewuwu uli ndi ubwino wake potengera mtengo womanga ndi kunyamula katundu, koma umakonda kung'ambika, kumasuka, matope, ndi kusokonekera. , subsidence, insufficient subgrade mphamvu, subgrade slippage ndi matenda ena ozama kwambiri. Sikophweka kuchiza matenda amsewu ozama kwambiri. Dongosolo lokonzekera lachikhalidwe nthawi zambiri ndi: musachiritse matenda ozama kwambiri atangoyamba kumene ndikusiya kuti akule; pamene matenda ozama kwambiri akukula kwambiri, aphimbe kapena kuwonjezera njira; ndipo pamene matenda ozama kwambiri ndi ovuta kwambiri kuti awononge magalimoto, ndiye kuti achite chithandizo chofukula, ndiko kuti, zomangamanga zazikulu ndi zazing'ono, ndi zovuta zomwe zimabweretsa ndizodziwikiratu, monga kukwera mtengo, kuwonongeka kwakukulu, Kukhudzidwa kwa magalimoto, kukhudzidwa kwa chilengedwe, ndi zina zotero. M'malo oterowo, kukulitsa moyo wautumiki wa misewu, kuchepetsa mtengo ndi zinyalala zomwe zimadza chifukwa cha kukonza misewu, komanso kukonza misewu yonse yakhala mitu yatsopano.
Ndi chitukuko chofulumira cha sayansi ndi luso lamakono, poyankha mavuto omwe ali pamwambawa, lingaliro lathu lalikulu ndikulimbitsa chitetezo cha tsiku ndi tsiku kukonza misewu, kuzindikira matenda ozama kwambiri, ndi kuchiza matenda ozama kwambiri.
Kukonzekera kodzitetezera kwa msewu ndikukonza kokonzekera bwino kwa msewu pamene njirayo ili bwino ndipo njirayo ikukwaniritsa zofunikira. Mosiyana ndi mfundo yachikhalidwe yokonza "osakonza msewu ngati sunathyoke", kukonza njira zodzitetezera kumatenda a asphalt kumadalira pa mfundo yakuti mapangidwe oyambirirawo sangasinthidwe kwenikweni, ndipo sikungofuna kupititsa patsogolo mphamvu za mpangidwe wapanjira. Pamene palibe kuwonongeka koonekeratu panjira kapena zizindikiro zazing'ono chabe za matenda, kapena ngati zidziwikiratu kuti matenda angayambe ndipo mkhalidwe wa pamsewu ukukumanabe ndi zofunikira za ntchito, yesetsani kukonza zowonongeka pamsewu.
Cholinga chachitetezo choteteza misewu ya phula ndikusunga mayendedwe abwino, kuchedwetsa kufota kwa msewu, kupewa kuchitika kwa matenda apamsewu kapena kufalikira kwa matenda ang'onoang'ono ndi zizindikiro za matenda; kukulitsa moyo wautumiki wapanjira, kuchepetsa kapena kuchedwetsa kuwongolera ndi kukonza matenda am'misewu; Mtengo wonse wokonza ndi wotsika pa nthawi yonse ya moyo wapanjira. Kuchulukitsidwa ndi kugwiritsa ntchito kukonza zodzitetezera kwapeza zotsatira za "kukonza pang'ono" kudzera mu "kukonza koyambirira" ndi "ndalama zochepa" kudzera mu "ndalama zoyamba".
Chosiyana ndi ukadaulo wamankhwala wopanda trenchless wa matenda akuya ndiukadaulo wakufukula. Ukadaulo wakufukula ndi njira yochizira yomwe imagwiritsidwa ntchito kwambiri pamatenda akuya amsewu ndipo nthawi zambiri imakhala njira yochizira. Popeza wosanjikiza m'munsi ndi pansi wosanjikiza pamwamba, njira mankhwala chikhalidwe amafuna kukumba pamwamba wosanjikiza pamaso pokonza m'munsi wosanjikiza. Monga tafotokozera pamwambapa, njirayi singotenga nthawi yaitali kuti imange, komanso imafuna kutsekedwa kwa magalimoto, zomwe zimakhudza kwambiri anthu komanso zachuma. Choncho, sikophweka kuzigwiritsa ntchito, ndipo zimatha kuchiritsidwa kokha pamene matenda ozama kwambiri m'mitsinje ayamba kukhala matenda aakulu kapena matenda oopsa kwambiri pamtunda. Ukadaulo wochizira matenda ozama kwambiri ndi ofanana ndi "opaleshoni yocheperako" m'zachipatala. Malo onse a ??"mabala" pochiza matenda a pamsewu nthawi zambiri saposa 10% ya ??matendawa. Choncho, zimapangitsa kuti msewu uwonongeke pang'ono, ndipo nthawi yomangayi ndi yaifupi komanso yokwera mtengo. Ndilochepa, silimakhudza kwambiri magalimoto pamsewu, ndipo silikonda zachilengedwe. Tekinolojeyi imayang'ana pa mawonekedwe a matenda okhazikika amisewu ndipo ndi oyenera kuchiza matenda ozama kwambiri m'misewu ya dziko langa. M'malo mwake, "Technical Regulations for Trenchless Treatment of Deep Road Diseases" isanalengezedwe, ukadaulo waukadaulo wothana ndi matenda am'misewu udagwiritsidwa ntchito nthawi zambiri m'dziko lonselo ndipo udapeza zotsatira zabwino.
Kukula kokhazikika kwamakampani okonza misewu sikungasiyanitsidwe ndi luso laukadaulo komanso malingaliro. Popanga zatsopano, zomwe zimatilepheretsa nthawi zambiri sikuti malingaliro ndi matekinoloje okha ndi abwino kwambiri, koma ngati tingayesetse kudutsa zopinga zachitsanzo choyambirira. Mwinamwake sichinapite patsogolo mokwanira ndipo chiyenera kusinthidwa pang'onopang'ono muzogwiritsira ntchito zamtsogolo, koma tiyenera kuthandizira ndi kulimbikitsa zatsopano.
