瀝(li)青(qing)(qing)(qing)混(hun)合(he)料(liao)(liao)的強度主(zhu)要(yao)(yao)表(biao)(biao)現在兩個方(fang)面(mian)。一是瀝(li)青(qing)(qing)(qing)與礦粉形成的膠結(jie)(jie)料(liao)(liao)的粘(zhan)結(jie)(jie)力(li)；另一是集(ji)料(liao)(liao)顆(ke)粒間的內(nei)摩(mo)阻力(li)和(he)(he)鎖結(jie)(jie)力(li)。礦粉細顆(ke)粒（大(da)多小(xiao)于0.075毫米）的巨大(da)表(biao)(biao)面(mian)積使(shi)瀝(li)青(qing)(qing)(qing)材料(liao)(liao)形成薄膜，從而提高了瀝(li)青(qing)(qing)(qing)材料(liao)(liao)的粘(zhan)結(jie)(jie)強度和(he)(he)溫度穩定(ding)性；而鎖結(jie)(jie)力(li)則主(zhu)要(yao)(yao)在粗集(ji)料(liao)(liao)顆(ke)粒之間產生(sheng)。選擇瀝(li)青(qing)(qing)(qing)混(hun)凝土礦料(liao)(liao)級配(pei)(pei)(pei)時要(yao)(yao)兼顧兩者(zhe)，以(yi)達(da)到(dao)加入適(shi)(shi)(shi)量(liang)瀝(li)青(qing)(qing)(qing)后混(hun)合(he)料(liao)(liao)能(neng)形成密實(shi)、穩定(ding)、粗糙度適(shi)(shi)(shi)宜、經久耐(nai)用(yong)(yong)(yong)的路(lu)面(mian)。配(pei)(pei)(pei)合(he)礦料(liao)(liao)有(you)多種方(fang)法，可以(yi)用(yong)(yong)(yong)公(gong)式(shi)計算，也(ye)可以(yi)憑經驗(yan)(yan)(yan)規定(ding)級配(pei)(pei)(pei)范(fan)圍，中(zhong)(zhong)國采(cai)用(yong)(yong)(yong)經驗(yan)(yan)(yan)曲線(xian)的級配(pei)(pei)(pei)范(fan)圍。瀝(li)青(qing)(qing)(qing)混(hun)合(he)料(liao)(liao)中(zhong)(zhong)的瀝(li)青(qing)(qing)(qing)適(shi)(shi)(shi)宜用(yong)(yong)(yong)量(liang)，應以(yi)試驗(yan)(yan)(yan)室試驗(yan)(yan)(yan)結(jie)(jie)果和(he)(he)工地實(shi)用(yong)(yong)(yong)情況來確(que)定(ding)，一般(ban)在有(you)關(guan)規范(fan)內(nei)均列有(you)可資參考的瀝(li)青(qing)(qing)(qing)用(yong)(yong)(yong)量(liang)范(fan)圍作為試配(pei)(pei)(pei)的指(zhi)導。當礦料(liao)(liao)品種、級配(pei)(pei)(pei)范(fan)圍、瀝(li)青(qing)(qing)(qing)稠度和(he)(he)種類、拌和(he)(he)設施、地區(qu)氣候(hou)及交通特征較固定(ding)時，也(ye)可采(cai)用(yong)(yong)(yong)經驗(yan)(yan)(yan)公(gong)式(shi)估算。
