Kukonza njira zodzitetezera kungathandize kupewa matenda apamsewu ndipo kwakhala chinthu chofunikira kwambiri pakukonza misewu. Imachedwetsa kuwonongeka kwa njira yodutsamo, imakulitsa moyo wautumiki wapanjira, imapangitsa kuti panjirayo ikhale yogwira ntchito bwino, ndikusunga ndalama zokonzera ndi kukonza. Nthawi zambiri amagwiritsidwa ntchito pazinthu zomwe sizinachitike. Panjira yomwe yawonongeka kapena yomwe ili ndi matenda ochepa chabe.

Njira yodzitetezera pokonza msewu ndi njira yosamalira bwino yomwe yalimbikitsidwa kwambiri m'dziko langa m'zaka zaposachedwa. Lingaliro lake ndikutenga miyeso yoyenera pa nthawi yoyenera pa gawo loyenera la msewu pamene msewu sunawonongeke mwadongosolo ndipo ntchito yautumiki yatsika kwambiri. Njira zosamalira zimachitidwa kuti mayendedwe apangidwewo azikhala bwino, kukulitsa moyo wautumiki wapanjirayo, ndikusunga ndalama zokonzera njira. Pakadali pano, matekinoloje odzitetezera omwe amagwiritsidwa ntchito kunyumba ndi kunja amaphatikiza chisindikizo cha chifunga, chisindikizo cha slurry, micro-surfacing, nthawi yomweyo miyala yamtengo wapatali, fiber seal, zokutira zopyapyala, chithandizo cha asphalt regeneration ndi njira zina zokonzera.

Panthawi yoyeserera yopanda katundu ya osakaniza phula, makinawo adagwa mwadzidzidzi, ndipo vuto loyambiranso lidalipo. Izi zingapangitse ogwiritsa ntchito kukhala ndi nkhawa, ndipo ntchitoyo idzachedwa. Vutoli liyenera kuthetsedwa posachedwa.

Chofalitsa cha chip mwala cholendewera ndi chinthu chatsopano chomwe kampani yathu idapanga ndikuchipanga bwino potengera zofalitsa zamwala zomwe zimagwiritsidwa ntchito pamsika pano. Makinawo atakhazikitsidwa pamsika, adalandira mayankho abwino kwambiri kuchokera kwa ogwiritsa ntchito.

Pali mitundu yambiri ya emulsion phula (kupangidwa: asphaltene ndi utomoni) zida. Emulsion phula (kupangidwa: asphaltene ndi utomoni) zida zikhoza kugawidwa mu intermittent ntchito mtundu, theka-yopitiriza ntchito mtundu, ndi Kupitiriza mitundu itatu opaleshoni, kudziwa za mitundu yosiyanasiyana ya emulsion phula chomera?
