Ikozvino kambani yedu inokurudzira iyo yakanyanya kupfava petroleum resin ye thermoplastic road pendi indasitiri, uye nzvimbo yekupfavisa ingangoita 120 â,Inotevera ndiyo mhedzisiro yebvunzo yezvinhu zvitatu zvemijenya.
Izvi zvinotevera zvichangobva kuunganidzwa zveceramic neiyo tsvuku ceramic aggregates uye grey ceramic aggregates.
Iko kumisa template yeinopenya pavement. Usati wadururira kongiri, zviumbwa zveparutivi zvinofanira kugadzikwa, uye kugadzika kwe template kunofanira kusangana nezvinodiwa zvekugadzira, kunofanira kunge kwakadzika uye kwakasimba, uye simbi yesimbi inofanira kusarudzwa. Iyo hupamhi hwepavement inodarika 5 metres inofanirwa kuve yakakamurwa template, uye hupamhi hwechikamu kazhinji 4-6 metres. Chikamu chinofanira kusanganiswa nechinzvimbo chejojo yekuwedzera.
