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。

（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，瀝li青qing麵mian層ceng無wu法fa完wan全quan恢hui複fu原yuan狀zhuang態tai，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，這zhe是shi形xing成cheng車che轍zhe的de根gen本ben所suo在zai。
在zai瀝li青qing麵mian層ceng中zhong使shi用yong玻bo纖xian土tu工gong格ge柵zha，其qi在zai瀝li青qing麵mian層ceng中zhong起qi到dao骨gu架jia作zuo用yong，瀝li青qing砼tong中zhong集ji料liao貫guan穿chuan於yu格ge柵zha間jian，形xing成cheng複fu合he力li學xue嵌qian鎖suo體ti係xi，限xian製zhi集ji料liao運yun動dong，增zeng加jia了le瀝li青qing麵mian層ceng中zhong的de橫heng向xiang約yue束shu力li，瀝li青qing麵mian層ceng中zhong各ge部bu分fen彼bi此ci牽qian製zhi，防fang止zhi了le瀝li青qing麵mian層ceng的de推tui移yi，從cong而er起qi到dao抵di抗kang車che轍zhe的de作zuo用yong。
（3） 抗低溫縮裂

玻bo纖xian土tu工gong格ge柵zha置zhi於yu瀝li青qing中zhong，使shi得de瀝li青qing砼tong的de拉la伸shen強qiang度du大da大da提ti高gao，足zu夠gou抵di抗kang住zhu較jiao大da的de拉la應ying力li而er不bu致zhi發fa生sheng路lu麵mian破po壞huai，即ji使shi因yin為wei局ju部bu區qu域yu產chan生sheng微wei小xiao裂lie紋wen，裂lie紋wen處chu的de應ying力li集ji中zhong，經jing玻bo纖xian土tu工gong格ge柵zha的de傳chuan遞di而er消xiao失shi，裂lie紋wen不bu會hui發fa展zhan成cheng裂lie縫feng。
（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）defanfudiya，shuizailiefengzhongchanshengshuiya，shuibuduandechongjiliqinghunheliao，daozhiliefengkuoda。lingyizhongshijiumiancengyuanyouliefeng，lujicenghuoxiacenglujicengchanshengdeliefengxiangshangfanshe，xinzhaolumianwufachengshouyindicengyidongerchanshengdejianqielihekangshenyingli，daozhilumianmiancengliefeng。
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。
