Uqhagamshelwano oluphinda: injongo kukuthi wenze ubunzima bomxube, obuqinisekileyo nobumbilini, oluyinkqubo yesitshixo ukuqinisekisa ukuqinisekisa ukuqinisekisa ukuqinisekisa ukuqinisekisa ukuqinisekisa kwe-asphalt concrete pavement.Ngenxa yoko, kufuneka kuxhotyiswe kufutshane nokujikeleza okuqala. Ubushumi obujikelezayo buba 115 ~ 135 °C, isantya buba 4 km / h, kwaye umqhubi womqhubi weshumi elinesithandathu usetyenziswa ukujikeleza amaxesha amathandathu. Ngexesha lokujikeleza, uyajikeleza ukusuka phantsi ukuya phezulu, kwaye amabhantshi okujikelezayo aphezulu nga1 / 3 ~ 1 / 2.
