塑料土工格柵在制造中聚合物的高分子會隨加熱延伸過程而重新排列定向，加強了分子鏈間的聯結力，達到了提高其強度的目的。其延伸率只有原板材的10%～15%。如果在土工格柵中加入炭黑等抗老化材料，可使其具有較好的耐酸、耐堿、耐腐蝕和抗老化等耐久性能。塑料土工格柵在試驗路檢測的使用。
Due to the polymer polymer reorientation and orientation along with the heating extension process in the manufacture of plastic geogrid, the bonding force between molecular chains is strengthened, and the purpose of improving its strength is achieved. Its elongation is only 10% - 15% of that of the original plate. If carbon black and other anti-aging materials are added to geogrids, they will have better durability such as acid, alkali resistance, corrosion resistance and aging resistance. The application of plastic geogrid in test road detection.
1.彎沉測定。試驗路鋪筑后，用BZZ-100型標準汽車、5.4m長桿彎沉儀，每隔50m測定混凝路面彎沉值。
1. Deflection measurement. After the test road is paved, the deflection value of concrete pavement is measured every 50m with bzz-100 standard automobile and 5.4m long rod deflectometer.
2.實側彎沉和平均彎沉L=11.50mm，均方差δ=2.21，代表彎沉L?代=15.14mm。
2. Real side deflection and average deflection L = 11.50mm, mean square deviation δ = 2.21, representing deflection l? Generation = 15.14mm.
3.按理論計算，在舊路上(δ=0.330mm)加鋪10cm瀝青混凝土，計算彎沉到達0.24mm，增加一層土工格柵計算彎沉值能達到0.14mm，相當于增加了8cm厚的瀝青混凝土，實測數據表明＞0.10mm的點占2.8%；≥0.15mm的點占2%，≥0.30點占1.1%。以上數據表明在瀝青混凝土中加設土工格柵作用明顯。
3. According to the theoretical calculation, when 10 cm asphalt concrete is paved on the old road (δ = 0.330mm), the calculated deflection reaches 0.24mm, and the calculated deflection value can reach 0.14mm by adding a layer of geogrid, which is equivalent to adding 8cm thick asphalt concrete. The measured data show that 2.8% points are more than 0.10mm, 2% are points ≥ 0.15mm, and 1.1% are points ≥ 0.30. The above data show that the effect of adding geogrid in asphalt concrete is obvious.
塑料土工格柵縱向搭接應依據瀝青攤鋪方向將前一幅置于后一幅之上。固定玻纖格柵時，不能將釘子釘于玻纖上，也不能用錘子直接敲擊玻纖，固定后如發現釘子斷裂或鐵皮松動，則應予以重新固定。玻纖格柵鋪設固定終了后，需用輕型膠輥壓路機適度碾壓穩定，使格柵與原路面粘結結實，并嚴厲控制車輛在其上行駛，嚴禁車輛在格柵層上急轉向、急剎車和傾倒混合腳料，以避免對塑料土工格柵形成損傷或毀壞。
The longitudinal lap of plastic geogrid should be based on the asphalt paving direction, and the former should be placed above the latter. When fixing the glass fiber grid, the nail shall not be nailed on the glass fiber, and the glass fiber shall not be directly hit with a hammer. If the nail is broken or the iron sheet is loose, it shall be re fixed. After the glass fiber grid is laid and fixed, it is necessary to roll and stabilize the glass fiber grid moderately with a light rubber roller, so that the grid and the original road surface are firmly bonded, and the vehicle driving on it is strictly controlled. It is strictly forbidden for vehicles to turn, brake and dump mixed materials on the grid layer, so as to avoid damage or damage to the plastic geogrid.
