彩(cai)(cai)色瀝(li)(li)青(qing)(qing)(qing)(qing)(qing)是(shi)如何(he)形成的(de)呢？橫州(zhou)瀝(li)(li)青(qing)(qing)(qing)(qing)(qing)站?——興通(tong)(tong)瀝(li)(li)青(qing)(qing)(qing)(qing)(qing)今天(tian)就給大家(jia)介紹下(xia)。1、瀝(li)(li)青(qing)(qing)(qing)(qing)(qing)結合料(liao)著色在瀝(li)(li)青(qing)(qing)(qing)(qing)(qing)或瀝(li)(li)青(qing)(qing)(qing)(qing)(qing)混(hun)合料(liao)中(zhong)(zhong)添加(jia)無機金屬鹽顏料(liao)代替同體積的(de)礦(kuang)粉，可以得(de)(de)到(dao)(dao)幾(ji)種彩(cai)(cai)色瀝(li)(li)青(qing)(qing)(qing)(qing)(qing)路面(mian)材(cai)(cai)料(liao)。例如，在瀝(li)(li)青(qing)(qing)(qing)(qing)(qing)混(hun)合料(liao)中(zhong)(zhong)加(jia)入占(zhan)集料(liao)總重量5%~7%的(de)氧化鐵(俗稱(cheng)紅土(tu))，可獲(huo)得(de)(de)紅色瀝(li)(li)青(qing)(qing)(qing)(qing)(qing)路面(mian)材(cai)(cai)料(liao)；添加(jia)5%~10%氧化鉻可獲(huo)得(de)(de)深綠色瀝(li)(li)青(qing)(qing)(qing)(qing)(qing)路面(mian)材(cai)(cai)料(liao)。但(dan)該方(fang)法得(de)(de)到(dao)(dao)的(de)彩(cai)(cai)色瀝(li)(li)青(qing)(qing)(qing)(qing)(qing)路面(mian)材(cai)(cai)料(liao)色調較低，亮(liang)度較暗，建(jian)議不要在瀝(li)(li)青(qing)(qing)(qing)(qing)(qing)混(hun)合料(liao)含石(shi)量大、交通(tong)(tong)磨耗(hao)
