，完wan全quan滿man足zu瀝li青qing路lu麵mian的de要yao求qiu，目mu前qian許xu多duo工gong程cheng已yi使shi用yong玻bo纖xian土tu工gong格ge柵zha。
　　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。

　　（3） 抗低溫縮裂
　　嚴yan寒han時shi期qi，瀝li青qing混hun凝ning土tu麵mian層ceng的de溫wen度du近jin於yu氣qi溫wen
，瀝li青qing砼tong遇yu冷leng收shou縮suo

，產chan生sheng拉la應ying力li

，在zai受shou到dao荷he載zai反fan複fu作zuo用yong下xia，拉la應ying力li進jin一yi步bu增zeng加jia，當dang拉la應ying力li超chao過guo瀝li青qing砼tong拉la伸shen強qiang度du時shi
，產chan生sheng裂lie紋wen，在zai裂lie紋wen兩liang端duan處chu
，拉la應ying力li更geng加jia集ji中zhong，裂lie紋wen逐zhu步bu形xing成cheng裂lie縫feng，造zao成cheng病bing害hai。
　　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

，zaiyushuishijie，shuijinruliefengzhong，zaijiaotonghezai（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。
