Basalt fiber geogrid kev ua tau zoo thiab kev tsim kho
Cov khoom ntawm Basalt Fiber Geogrid
(1)Siab tawg zog: Lub zog tawg ntawm basalt fiber ntau geogrid nyob rau hauv ob qho tib si warp (longitudinal) thiab weft (transverse) cov lus qhia yog siab dua li ntawm cov iav fiber ntau geogrid nyob rau hauv tib linear ceev.
(2)Tsawg Elongation: Qhov tawg elongation ntawm basalt fiber ntau geogrid hauv warp thiab weft cov lus qhia yog ≤3%.
(3)Lub cev zoo heev thiab Tshuaj Kev ruaj ntseg: Basalt fiber nws tus kheej muaj zog tiv thaiv acids, alkalis, thiab corrosion. Lub geogrid tuaj yeem tiv taus cov tshuaj yaig, kev puas tsuaj ntawm lub cev, kev hloov pauv huab cua, thiab kev puas tsuaj lom yam tsis muaj kev poob haujlwm.
(4)Creep Resistance: Basalt fiber, raws li cov khoom siv txhawb zog, tsis nkag mus. Nws lub peev xwm los tiv thaiv deformation nyob rau hauv lub sij hawm ntev loads kom lub sij hawm ntev kev ua tau zoo tuav.
(5)Kub-kub Resistance: Tom qab cua sov ntawm 170 ° C rau 1 teev, qhov ruaj khov tensile tawg lub zog nyob rau hauv warp thiab weft cov lus qhia tseem ≥90%.
(6)Tsawg-kub Resistance: Tom qab khov ntawm -40 ° C rau 1 teev, qhov ruaj khov tensile tawg lub zog nyob rau hauv warp thiab weft cov lus qhia tseem ≥80%.
(7)Aggregate Interlocking thiab txwv: Ob-dimensional grid qauv ntawm geogrid mechanically interlocks thiab txwv kev txav ntawm asphalt mix aggregates. Nyob rau hauv lub load, qhov no txhim khu lub peev xwm load-bearing, txhim kho compaction, optimizes load hloov, thiab txo deformation.
Qhov zoo ntawm Basalt Fiber Geogrid hauv Asphalt Pavements
Asphalt-coated basalt fiber ntau geogrid txuas ntxiv lub neej qaug zog ntawm cov txheej txheem pavement, txo cov nqi, thiab txhim kho cov peev txheej engineering. Qhov no yog vim nws lub peev xwm los tiv thaiv kev tawg tawg, txhim khu kev tiv thaiv rau transverse shear tsis ua hauj lwm, thiab dissipate tawg zog zoo. Nrog nce tsheb thauj mus los thiab tsheb thauj khoom, cov pavements ntsib kev puas tsuaj loj, tshwj xeeb yog vim muaj tsheb loj. Reflective cracking nyob rau hauv asphalt overlays ntawm cov laus pavements tseem yog ib qho teeb meem tseem ceeb. Txawm hais tias qhov tawg ntawm lawv tus kheej tsis tuaj yeem cuam tshuam kev ua haujlwm ntawm txoj kev pavement, ib puag ncig yam tseem ceeb (xws li, plua plav, ya raws, oxidation) ua kom tawg tawg, ua kom luv luv overlay lifespan. Basalt fiber geogrids txo qhov no los ntawm kev faib cov kev ntxhov siab, txhim kho lub zog tensile, ncua kev cuam tshuam kev tawg, thiab ua kom lub neej ntev kev pab cuam pavement.
Kev tsim kho txoj hauv kev rau Basalt Fiber Geogrid hauv Asphalt Pavements
(1)Kev xaiv Binder: Siv ceev ceev-setting emulsified asphalt los yog nruab nrab-/ceev-kho kua asphalt rau lub tsho tiv no.
(2)Yuav tsum tau nruab: Xyuas kom lub hauv paus nto yog tiaj, compact, thiab huv si. Tso lub geogrid smoothly tsis overlaps, curling, los yog twisting. Overlap nyob ib sab geogrids los ntawm 0.3 m transversely, txuas lawv txhua txhua 1.5 m nrog No. 8 steel hlau. Ruaj ntseg geogrid rau hauv av nrog U-puab ntsia hlau spaced 1.3-2 m sib nrug.
(3)Kev npaj nto: Tshem tawm cov kab mob (piv txwv li, plua plav, roj, noo noo) txhawm rau txhim kho kev sib raug zoo. Siv tack coat emulsified asphalt sparingly tom qab kho tag nrho. Orient cov dej-soluble rov qab downward thaum lub installation.
(4)Overlap Specifications: Longitudinal overlaps yuav tsum ≥20 cm, thiab transverse overlaps ≥15 cm. Muab cov geogrid ua ntej dhau ib qho tom ntej hauv kev taw qhia ntawm asphalt paving. Tsis txhob ntsia ncaj qha rau hauv geogrid lossis hammering nws. Rov kho cov ntsia hlau xoob lossis daim hlau. Tom qab kev teeb tsa, maj mam compact lub geogrid nrog cov roj hmab-log cov menyuam kom paub meej adhesion.
(5)Sijhawm Compaction: Tam sim no dov minimizes yoj tsim. Kev tswj hwm nruj thiab kev ua haujlwm txawj yog qhov tseem ceeb rau kev ua haujlwm zoo.
Cov lus xaus
(1) Basalt fiber ntau geogrid outperforms pa geogrids nrog siab modulus, lub zog, tsis muaj creep, tawg tsis kam, laus / corrosion kuj, thiab customizable tsim, ua rau nws zoo tagnrho rau txoj kev engineering.
(2) Nws siv txo qhov ntim ntawm kev tsim kho, ua kom nrawm dua, thiab txo cov nqi.
(3) Nws txo cov nqi kho mob thiab txuas ntxiv asphalt pavement lifespan.
