路(lu)(lu)牙(ya)石(shi)(shi)(shi)(shi)(shi)特點：路(lu)(lu)牙(ya)石(shi)(shi)(shi)(shi)(shi)根(gen)據(ju)用料的(de)(de)不同(tong)，一般(ban)情況下分(fen)為兩種(zhong)：即混凝土路(lu)(lu)牙(ya)石(shi)(shi)(shi)(shi)(shi)和石(shi)(shi)(shi)(shi)(shi)材路(lu)(lu)牙(ya)石(shi)(shi)(shi)(shi)(shi)。根(gen)據(ju)路(lu)(lu)牙(ya)石(shi)(shi)(shi)(shi)(shi)的(de)(de)截(jie)面尺寸復可(ke)以(yi)分(fen)為H型(xing)路(lu)(lu)牙(ya)石(shi)(shi)(shi)(shi)(shi)、T型(xing)路(lu)(lu)牙(ya)石(shi)(shi)(shi)(shi)(shi)、R型(xing)路(lu)(lu)牙(ya)石(shi)(shi)(shi)(shi)(shi)、F型(xing)路(lu)(lu)牙(ya)石(shi)(shi)(shi)(shi)(shi)、TF型(xing)立牙(ya)石(shi)(shi)(shi)(shi)(shi)和P型(xing)平牙(ya)石(shi)(shi)(shi)(shi)(shi)。辨別路(lu)(lu)沿(yan)石(shi)(shi)(shi)(shi)(shi)的(de)(de)方法可(ke)以(yi)用眼觀、尺量(liang)、耳(er)聽(ting)、實(shi)驗這(zhe)(zhe)幾種(zhong)方式。眼觀就是(shi)觀察石(shi)(shi)(shi)(shi)(shi)材的(de)(de)外表結構(gou)，好(hao)質量(liang)的(de)(de)石(shi)(shi)(shi)(shi)(shi)材其外表有(you)均勻的(de)(de)細(xi)料結構(gou)，看著有(you)細(xi)膩的(de)(de)質感。選(xuan)擇路(lu)(lu)沿(yan)石(shi)(shi)(shi)(shi)(shi)建議(yi)選(xuan)擇顏(yan)色花色比(bi)較(jiao)(jiao)一致和諧的(de)(de)，這(zhe)(zhe)樣鋪設下來也比(bi)較(jiao)(jiao)美觀。在挑選(xuan)路(lu)(lu)沿(yan)石(shi)(shi)(shi)(shi)(shi)的(de)(de)時(shi)候可(ke)以(yi)聽(ting)一聽(ting)路(lu)(lu)沿(yan)石(shi)(shi)(shi)(shi)(shi)的(de)(de)擊(ji)打的(de)(de)聲(sheng)(sheng)音，如果聲(sheng)(sheng)音很清脆(cui)那就質量(liang)比(bi)較(jiao)(jiao)好(hao)。

路(lu)(lu)牙(ya)(ya)石(shi)(shi)特(te)點(dian)(dian)：路(lu)(lu)牙(ya)(ya)石(shi)(shi)根(gen)(gen)據(ju)用料的不同，一般情況下分為兩種：即混凝土(tu)路(lu)(lu)牙(ya)(ya)石(shi)(shi)和(he)石(shi)(shi)材路(lu)(lu)牙(ya)(ya)石(shi)(shi)。根(gen)(gen)據(ju)路(lu)(lu)牙(ya)(ya)石(shi)(shi)的截(jie)面尺寸(cun)復可(ke)以分為H型路(lu)(lu)牙(ya)(ya)石(shi)(shi)、T型路(lu)(lu)牙(ya)(ya)石(shi)(shi)、R型路(lu)(lu)牙(ya)(ya)石(shi)(shi)、F型路(lu)(lu)牙(ya)(ya)石(shi)(shi)、TF型立牙(ya)(ya)石(shi)(shi)和(he)P型平(ping)牙(ya)(ya)石(shi)(shi)。路(lu)(lu)牙(ya)(ya)石(shi)(shi)它的形式(shi)有(you)(you)立式(shi)，斜式(shi)和(he)平(ping)式(shi)等。是(shi)花崗巖材質(zhi)，具(ju)有(you)(you)石(shi)(shi)質(zhi)堅(jian)硬，耐(nai)(nai)磨損、耐(nai)(nai)酸堿(jian)、的特(te)點(dian)(dian)。pc路(lu)(lu)牙(ya)(ya)的優點(dian)(dian):PC具(ju)有(you)(you)優異的電絕緣性(xing)(xing)(xing)(xing)、延伸性(xing)(xing)(xing)(xing)、尺寸(cun)穩定性(xing)(xing)(xing)(xing)、耐(nai)(nai)化學腐蝕性(xing)(xing)(xing)(xing)、耐(nai)(nai)熱性(xing)(xing)(xing)(xing)、耐(nai)(nai)寒性(xing)(xing)(xing)(xing)不掉色(se)等特(te)點(dian)(dian)。具(ju)有(you)(you)自熄、阻燃(ran)、***、可(ke)著色(se)。容易加工，價格(ge)低廉。路(lu)(lu)牙(ya)(ya)石(shi)(shi)用一般的實(shi)驗(yan)進行試一下，通常在(zai)(zai)路(lu)(lu)沿(yan)石(shi)(shi)的反面滴上一小滴墨(mo)水，如(ru)墨(mo)水很快四(si)處渙散浸出(chu)，即表明(ming)路(lu)(lu)沿(yan)石(shi)(shi)內部顆粒較(jiao)松或(huo)存(cun)在(zai)(zai)顯微(wei)裂隙，路(lu)(lu)沿(yan)石(shi)(shi)質(zhi)量欠(qian)好(hao)；反之(zhi)，若墨(mo)水滴在(zai)(zai)原處不動(dong)，則闡(chan)明(ming)路(lu)(lu)沿(yan)石(shi)(shi)細密質(zhi)地(di)好(hao)。
