　　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

　　瀝li青qing路lu麵mian必bi須xu具ju有you一yi定ding的de承cheng載zai能neng力li，在zai規gui定ding的de時shi間jian內nei不bu能neng發fa生sheng疲pi勞lao破po壞huai。瀝li青qing路lu麵mian在zai直zhi接jie與yu車che輪lun接jie觸chu的de下xia麵mian層ceng受shou到dao壓ya力li，在zai輪lun載zai邊bian緣yuan以yi外wai的de區qu域yu，麵mian層ceng受shou到dao拉la力li作zuo用yong，由you於yu兩liang處chu受shou力li區qu域yu所suo受shou力li性xing質zhi不bu同tong，而er又you彼bi此ci緊jin靠kao，因yin此ci在zai兩liang塊kuai受shou力li區qu域yu的de交jiao界jie處chu即ji力li的de突tu變bian處chu發fa生sheng破po壞huai
，在zai長chang期qi荷he載zai的de作zuo用yong下xia，發fa生sheng疲pi勞lao開kai裂lie。

　　玻(bo)纖(xian)土(tu)工(gong)格(ge)柵(zha)在(zai)瀝(li)青(qing)麵(mian)層(ceng)中(zhong)

，能(neng)夠(gou)將(jiang)上(shang)述(shu)的(de)壓(ya)應(ying)力(li)與(yu)拉(la)應(ying)力(li)分(fen)散(san)，在(zai)兩(liang)塊(kuai)受(shou)力(li)區(qu)域(yu)之(zhi)間(jian)形(xing)成(cheng)緩(huan)衝(chong)帶(dai)

，減(jian)少(shao)了(le)應(ying)力(li)突(tu)變(bian)對(dui)瀝(li)青(qing)麵(mian)層(ceng)的(de)破(po)壞(huai)。同(tong)時(shi)玻(bo)璃(li)纖(xian)維(wei)土(tu)工(gong)格(ge)柵(zha)的(de)低(di)延(yan)伸(shen)率(lv)減(jian)少(shao)了(le)路(lu)麵(mian)的(de)彎(wan)沉(chen)量(liang)
，保(bao)證(zheng)了(le)路(lu)麵(mian)不(bu)會(hui)發(fa)生(sheng)過(guo)度(du)變(bian)形(xing)。

　　（2） 耐高溫車轍

　　瀝li青qing混hun凝ning土tu在zai高gao溫wen時shi具ju有you流liu變bian性xing，在zai車che輛liang荷he載zai作zuo用yong下xia，受shou力li區qu域yu產chan生sheng凹ao陷xian，車che輛liang荷he載zai撤che除chu後hou

，即ji產chan生sheng了le塑su性xing變bian形xing，在zai車che輛liang反fan複fu碾nian壓ya的de作zuo用yong下xia，塑su性xing變bian形xing不bu斷duan積ji累lei，形xing成cheng車che轍zhe。通tong過guo瀝li青qing麵mian層ceng結jie構gou分fen析xi可ke知zhi
，高gao溫wen下xia的de瀝li青qing混hun凝ning土tu在zai受shou到dao荷he載zai的de碾nian壓ya作zuo用yong，形xing成cheng了le微wei量liang的de波bo形xing流liu變bian，麵mian層ceng中zhong沒mei有you任ren何he可ke以yi約yue束shu瀝li青qing混hun凝ning土tu流liu變bian的de骨gu架jia材cai料liao，造zao成cheng瀝li青qing麵mian層ceng流liu變bian的de累lei積ji疊die加jia

　　（4） 延緩反射裂縫

　　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。
