What is Geotextile in Road Construction

Geotextile in road construction are a widely used component in road construction. Their ability to separate, filter, protect, and add tensile strength to soils by reinforcing makes poor soils more suitable for construction. 

In Dutum Construction Group, We are committed to creating and sustaining quality results that stand and that involve using the best quality materials for our infrastructural projects. 

In this article, we will explore the uses of geotextiles in road construction, as well as the benefits and why you should trust Dutum Group for your road construction projects. 

What is Geotextile in road construction? 

Geotextiles are permeable fabrics that are made from synthetic or natural materials. They are designed to interact with soil and other materials to provide separation, reinforcement, and filtration functions.

Types of Geotextiles

Geotextiles can be woven or non-woven and are available in various thicknesses and permeabilities. The most common materials used to manufacture geotextiles are polypropylene and polyester.   

1. Woven

Woven fabric geotextiles are the most common, and their manufacturing methods are similar to clothing textiles. This type of geotextile is made from two sets of parallel threads or yarns.

2. Nonwoven

Nonwoven geotextiles are made from continuous yarn filaments or short staple fibers. They are bonded with thermal, chemical, or mechanical techniques or a combination of techniques.

3. Knitted

Knitted geotextiles are created by interlocking a series of yarn loops together. These geosynthetics combine the knitting technique with other methods like weaving.

Uses of Geotextiles in road construction

1. Separation

Geotextiles play a crucial role in construction by preventing soil intermixing and preserving soil characteristics. When installed between different soil types, geotextiles stop water from causing soil contamination, ensuring the structural integrity of roads, railways, and other infrastructure. By separating soils and aggregates, geotextiles maintain drainage properties and strength. Their unique thickness and permeability properties allow water to flow while preventing contamination. Typical applications of geotextiles include:

• Landfills and stone base courses
• Paved and unpaved roads
• Railroads
• Geomembranes and sand drainage layers

2. Filtration

Geotextiles with filtration properties are used to facilitate bidirectional water movement, preventing fine aggregates from shifting between soil layers. These geotextiles, available in woven and nonwoven forms, rely on two key properties: porosity and permeability. By leveraging these properties, geotextiles can also promote lateral water flow, mitigating kinetic energy from groundwater capillary rise. Applications for these geotextiles include vertical and horizontal installations, effectively addressing drainage issues along roads and structures.

3. Reinforcement

When designing geotextiles to enhance soil properties, three crucial factors come into play: minimizing soil movement and friction, bearing loads, and boosting shear strength. Geotextile reinforcement serves a similar purpose to steel reinforcement in concrete, providing stability and support. Geotextiles are particularly useful for constructing embankments and roads on unstable soils, with design parameters guided by geotechnical engineering expertise.

4. Sealing

Geotextile fabrics can be treated with asphalt or other specialized mixes, rendering them impermeable and capable of blocking vertical water flow. For this specific use, nonwoven geotextiles are required. Impermeable geotextiles serve as a barrier to prevent pollutants from contaminating soil and groundwater, and can also help conserve potable water by minimizing evaporation losses.

Benefits of Using Geotextiles in Road Construction

The use of geotextiles in road construction offers several benefits, including:

1. Improved road stability and durability:

Geotextiles can improve the stability of soil and other materials, which reduces the risk of road instability and associated problems.

2. Reduced maintenance costs:

Geotextiles can reduce the need for frequent repairs and maintenance, which saves time and money.

3. Enhanced safety:

Geotextiles can improve road safety by reducing the risk of accidents caused by road instability and associated problems.

4. Environmental benefits:

Geotextiles can reduce the environmental impact of road construction by minimizing soil erosion and improving water quality.

5. Cost savings:

Geotextiles can provide cost savings by reducing the need for expensive repairs and maintenance and extending the roads’ lifespan.
