　　玻纖應用於瀝青道路時
，可在以下幾方麵發揮作用。

　　（1）抗疲勞開裂

　　（4） 延緩反射裂縫

　　裂(lie)縫(feng)產(chan)生(sheng)的(de)反(fan)射(she)有(you)兩(liang)種(zhong)，一(yi)種(zhong)是(shi)麵(mian)層(ceng)產(chan)生(sheng)裂(lie)縫(feng)後(hou)，裂(lie)縫(feng)向(xiang)下(xia)反(fan)射(she)
，破(po)壞(huai)下(xia)層(ceng)結(jie)構(gou)，降(jiang)低(di)路(lu)麵(mian)結(jie)構(gou)強(qiang)度(du)
，在(zai)雨(yu)水(shui)時(shi)節(jie)，水(shui)進(jin)入(ru)裂(lie)縫(feng)中(zhong)，在(zai)交(jiao)通(tong)荷(he)載(zai)（輪胎壓力）的(de)反(fan)複(fu)抵(di)壓(ya)
，水(shui)在(zai)裂(lie)縫(feng)中(zhong)產(chan)生(sheng)水(shui)壓(ya)，水(shui)不(bu)斷(duan)的(de)衝(chong)擊(ji)瀝(li)青(qing)混(hun)合(he)料(liao)

，導(dao)致(zhi)裂(lie)縫(feng)擴(kuo)大(da)。另(ling)一(yi)種(zhong)是(shi)舊(jiu)麵(mian)層(ceng)原(yuan)有(you)裂(lie)縫(feng)，路(lu)基(ji)層(ceng)或(huo)下(xia)層(ceng)路(lu)基(ji)層(ceng)產(chan)生(sheng)的(de)裂(lie)縫(feng)向(xiang)上(shang)反(fan)射(she)
，新(xin)罩(zhao)路(lu)麵(mian)無(wu)法(fa)承(cheng)受(shou)因(yin)底(di)層(ceng)移(yi)動(dong)而(er)產(chan)生(sheng)的(de)剪(jian)切(qie)力(li)和(he)抗(kang)伸(shen)應(ying)力(li)，導(dao)致(zhi)路(lu)麵(mian)麵(mian)層(ceng)裂(lie)縫(feng)。

　　在瀝青罩麵層中加鋪玻纖土工格柵夾層，抑製應力，釋放應變
，增強瀝青混凝土整體強度
，達到防止裂縫向上或向下反射的目的。
