Okwangoku, iipeyinti zokumakisha zendlela zangaphandle zisekelwe emanzini kwaye ziphuhliswa ngokukhawuleza. Ngaphezulu kwe-90% yeepeyinti zophawu lwendlela kumazwe aphuhlileyo anjenge-United States, iJamani, iSpain, iSweden, neFinland asebenzisa iimveliso ezisekwe emanzini. Ngenxa yokuqalisa kwangethuba kweendlela zokumakisha zendlela yangaphandle kunye nophuhliso olukhawulezayo lwetekhnoloji, i-nanometer yokumakisha indlela yokumakisha, iicandelwana ezimbini zokumakishwa kwendlela yokumakisha, i-pigment-coated-coated yendlela yokumakisha, njalo njalo.
Kwiinyanga ezimbalwa okanye neentsuku ezimbalwa emva kokuveliswa, kuya kubakho utshintsho olukhulu kwi-viscosity, i-skin skinning, njl., okukhokelela ekusebenzeni kakubi kokutshiza kwengubo kunye nesiphumo esibi sokuvula; ixesha lokungabambeleli alikwazi ukuhlangabezana neemfuno zangempela zokwakhiwa kweendlela kunye nokuchaphazela ukwakhiwa Ukuhamba kakuhle kwezithuthi ngelo xesha.
Ngoku kukho iifektri zepeyinti zepeyinti ezikhulu nezincinci eziphawula indlela eTshayina. Imizi-mveliso emininzi emikhulu enamandla ngokwentelekiso yobugcisa nayo sele iqalisile ukuvelisa iipeyinti zokuphawula zendlela ezisekwe emanzini. Ukuqinisekisa umgangatho weepeyinti zokuphawula ezindleleni, iSebe lezoThutho liqulunqe amashishini afanelekileyo. Imigangatho ikhuthaza ngamandla iindlela zokumakishwa kweendlela ezisekelwe emanzini. Uhlalutyo lwengcaphephe yomgangatho womgangatho: Ngophuhliso lweshishini lezothutho lwendlela yaseTshayina kunye nokwanda ngokukhawuleza kobunini bezithuthi, imfuno yokumakisha iya kunyuka. Ngokunyuka kolwazi lwabantu malunga nokukhuselwa kwendalo kunye nenkxaso yemigaqo-nkqubo yesizwe kunye nemimiselo, imfuno yokumakishwa kweendlela ezisekelwe emanzini Isixa sikhulu.
Iimveliso zepeyinti zepeyinti zelizwe ezisekelwe emanzini zisetyenzisiwe kulwakhiwo lwezikhululo zeenqwelomoya, oohola bendlela, kunye nezinye iiprojekthi, ezikwaveze imiqobo ethile yobugcisa. Iingxaki ezikhoyo ngoku zeendlela ezibonisa indlela ezibonakala ngayo zibandakanya: ukukrazuka okulambathayo kunye nokumelana nemozulu, kwaye kufuneka zicocwe kwakhona kwisithuba se-1a; ukunganyangeki kwamanzi kunye nokuchasana kwe-alkali, ukungakwazi ukuhlangabezana neemfuno zangempela zendlela yokungena emanzini; ukunganyangeki kwebala, kunye nomphezulu wokumakisha kulula ukuqokelela uthuli. Ukuchaphazela i-coefficient ye-retroreflective kunye nokunciphisa umphumo wokubonakalisa; uzinzo olulambathayo lokugcina.
