Coloured asphalt, inozivikanwawo sesimende yeruvara, simende inoteedzera zvikamu zve petroleum asphalt uye inogadziriswa nekusanganisa petroleum resin neSBS modifier uye zvimwe zvinhu zvemakemikari. Iyi asphalt pachayo haina ruvara kana isina ruvara, asi Rima brown, mumakore achangopfuura, iri pamwe chete inonzi colored asphalt nekuda kwemaitiro emusika. Parizvino, China ane mavara asphalt kongiri pavements inogona kukamurwa kuva maviri makuru marudzi: mhando yokutanga inoumbwa nokushandisa läpinäkyvä kana translucent asphalt binder sebinder, uyezve kuwedzera inorganic pigments kumusanganiswa asphalt; mhando yechipiri ndiyo Inogadzirwa nesemende inoonekera kana inopenya. Inobva yaumbwa nekusanganisa yakasikwa colored mineral materials as aggregates. Saka ndeapi maitiro emavara asphalt kongiri pavement?

Shongedza guta, vandudza mamiriro emigwagwa, uye ratidza maitiro emadhorobha. Inonyanya kushandiswa mumigwagwa yevanofamba netsoka, nzvimbo dzenzvimbo, masikweya, mapaki, migwagwa nedzimwe nzvimbo. Inopindirana neuswa hwakasvibirira hwakapoteredza, miti, maruva, nezvimwewo, nekudaro kushongedza nharaunda uye kupa vanhu pfungwa yemaitiro. Nakidzwa nekunaka. Iine basa rekuronga nekudzora traffic, uye rinonyanya kushandiswa kusiyanisa zvikamu zvemigwagwa uye nzira dzine mabasa akasiyana ekusimudzira kucherechedzwa kwenzvimbo yemugwagwa, huwandu hwetraffic hwemugwagwa uye kuchengetedzwa kwemigwagwa. Iine maitiro akanaka emugwagwa. Pasi pesimba rekushisa kwakasiyana-siyana uye mamiriro ekunze, kugadzikana kwayo kwepamusoro-kupisa, kusagadzikana kwekukuvara kwemvura uye kusimba kwakanaka kwazvo, uye hairatidzi kuderera, asphalt film peeling, nezvimwewo, uye ine mukaka wakanaka unobatana nehwaro hwepasi. . Muvara wakajeka uye unogara kwenguva refu, hauperi, unogona kumira kutonhora kwakanyanya kwe77 ° C uye kutsika kwakadzika kwe -23 ° C, uye zviri nyore kuchengetedza. Nesimba rakasimba rekunyudza mutsindo, matayi emotokari haaburitse ruzha rwakasimba nekuda kwekudzvanywa kwemhepo kana ichikunguruka nekumhanya kukuru mumugwagwa, uye inogonawo kutora imwe ruzha kubva kunze kwenyika. Iine elasticity yakanaka uye kushanduka, kunzwa kwakanaka kwetsoka, kwakakodzera kufamba nevakwegura, uye ine yakanaka anti-slip performance munguva yechando.
