What specific considerations should be taken into account during the construction of Zhejiang short-filament geotextiles to enhance their utilization?

2020-12-29
Adding an asphalt overlay on existing cement concrete pavement is a commonly used pavement rehabilitation technique. It offers several advantages, including short construction time, low cost, minimal disruption to traffic, and excellent restoration of the pavement's service performance. However, a major issue with this method is the frequent occurrence of reflective cracks in the asphalt overlay, which can undermine the long-term durability of the repaired surface. Zhejiang Shaoxing Short-Fiber Geotextile It is one of the primary measures to delay reflective cracking.
During the construction of the overlay layer, special attention was paid to the following aspects:
1. Construction Preparation: Choose a hot weather period, and before laying the geotextile, thoroughly clean the existing cement concrete pavement. For areas where the original slabs are damaged, first remove the broken concrete, then use a 6% cement-stabilized gravel mixture to level and compact the surface—ensuring that the final surface meets the required smoothness standards.
2. Asphalt Application: Use ordinary hot asphalt as the tack coat, with the asphalt application rate determined through testing—typically controlled between 0.9 and 1.1 kg/m². The asphalt will be applied using an asphalt distributor, and the application rate must be pre-tested to ensure compliance. Additionally, the width of the asphalt layer should be set slightly wider than required. Zhejiang Shaoxing Short-Fiber Geotextile 20 cm; the spreading rate depends on the actual speed of geotechnical material placement and compaction. For areas where asphalt is applied in excess, remove it promptly.
3. Laying out Zhejiang Shaoxing Short-Fiber Geotextile : Zhejiang Shaoxing Short-Fiber Geotextile The paving is scheduled to take place before the asphalt loses its adhesion. Zhejiang Shaoxing Short-Fiber Geotextile Laying requirements include being smooth, free of folds and wrinkles; after installation, use a tire roller to compact the surface thoroughly for tight bonding. Zhejiang Shaoxing Short-Fiber Geotextile The overlap length is 15 cm; in areas where the short-fiber geotextile from Shaoxing, Zhejiang, shows poor bonding and adhesion, it should be removed and re-laid. Zhejiang Shaoxing Short-Fiber Geotextile In areas with wrinkles, manually flatten them or apply asphalt by brushing, then carefully reattach the folded sections so that, after rolling, the top and bottom layers align properly. Zhejiang Shaoxing Short-Fiber Geotextile Stuck together.
4. Asphalt Mixture Paving: At Zhejiang Shaoxing Short-Fiber Geotextile After paving, hot asphalt mixture should be spread immediately, with its temperature kept below 160°C. Since the road remains open to traffic, and to ensure smooth passage for other vehicles, Zhejiang Shaoxing Short-Fiber Geotextile Sprinkle some sand or hot stone chips on top; immediately after the asphalt mixture is spread, begin rolling until it meets the requirements of the construction technical specifications.
For Zhejiang Shaoxing Short-Fiber Geotextile The connection work must not be carried out arbitrarily—there are many issues that require careful attention. Only after performing a proper and accurate connection can we achieve the desired results. Under normal circumstances, there should be no horizontal connections on the slope surface (connections must follow the slope’s contour without intersecting it), except in areas designated for repairs. If this is not addressed… Zhejiang Shaoxing Short-Fiber Geotextile The connection is made using stitching, and the sewing thread must be made of the same material as or a superior grade to the short-fiber geotextile from Shaoxing, Zhejiang. Additionally, the stitching thread must be resistant to chemicals and UV radiation.
Surgical sutures and Zhejiang Shaoxing Short-Fiber Geotextile There should be a noticeable color difference for easy inspection. During installation, pay special attention to the seams to ensure that no soil or gravel from the surrounding layers makes its way into the middle of the Zhejiang Shaoxing short-fiber geotextile. Zhejiang Shaoxing Short-Fiber Geotextile Damage and repairs at the stitching joints require resewing and patching, ensuring that the ends of any skipped stitches are properly reattached. Once you become familiar with these processes, it will greatly enhance the efficiency of our work.
