Revitalise Your Tracks: Road Reclamation Explained

The Problem with Worn Tracks

Bashing and crashing along worn-out farm tracks is a pretty tedious pastime, but it is one many farmers will endure for years, fearing that the cost of putting it right will be extortionate. However, as long as your roadway has a decent quantity of stone in its construction, it won’t necessarily be that expensive to put right. Across the length and breadth of the country there are now several contractors offering to reclaim your existing tracks, rather than correcting them by bringing in vast quantities of new stone. This basically involves ripping up and crushing the motley collection of stones and aggregate you already have, before consolidating them into a decent surface.

What is Road Reclamation?

Road reclamation, often referred to as track renovation or recycling, is a sustainable and cost-effective method of repairing and maintaining existing road surfaces, particularly prevalent in agricultural, forestry, and rural settings. Instead of the traditional approach of excavating and importing large volumes of new aggregate, road reclamation focuses on utilising and reprocessing the existing materials of the track. This process breathes new life into tired and damaged surfaces, transforming them into durable and reliable pathways.

Companies like PSM Plant and Agricultural Services and Renutrack specialise in this field. They offer a comprehensive service that ranges from simple maintenance to more intensive interventions such as surface scarifying, deep ripping, and crushing. The ultimate goal is to create a rejuvenated and robust road surface from the materials already present.

Can Any Track Be Restored?

The good news is that, according to experts in the field, almost any track can be restored. However, the complexity and cost can vary depending on the existing construction. The simplest and most straightforward restorations are typically for tracks that are predominantly made of stone, with a depth of at least 10 inches (25cm). A good width is also beneficial, as it allows vehicles to vary their wheel marks, distributing wear more evenly and prolonging the life of the surface.

Tracks that are primarily stone but have a few thinner sections can also be effectively repaired. This often involves excavating any underlying soil and redistributing material from thicker parts of the track, or supplementing with new material if necessary. Even heavily damaged tarmac roads can be successfully crushed and resurfaced using reclamation techniques.

For tracks with a minimal stone content, stabilisation methods involving hydrated lime and cement can be employed to create a durable earth roadway that performs well in certain conditions. In cases where the existing material is insufficient or unsuitable, starting from scratch may be the only viable option to achieve a high-quality finish.

Key Track Maintenance Tips:

• Keep the track free from soil and vegetation.
• Vary wheelings to prevent the formation of ruts or potholes.
• Drive sensibly on new or reclaimed tracks until they have properly bedded in.
• Remove encroaching grass verges and ensure drainage channels are kept clear.

The Road Reclamation Process: A Step-by-Step Guide

The process of road reclamation is a multi-stage operation designed to transform a degraded surface into a smooth, stable, and long-lasting track. Here’s a breakdown of the typical steps involved:

1. Soil and Vegetation Removal

Soil and vegetation are detrimental to the integrity of a farm track. Grass and weeds take root, and their root structures degrade the surface. These plants also retain moisture, further weakening the track. Grass verges are particularly problematic as they impede water drainage and gradually encroach onto the road, narrowing its effective width. Therefore, the first crucial step is to meticulously scrape off all soil, vegetation, and verges. This is often done using excavators equipped with hydraulic tilt buckets. Any usable stone that may have been pushed into the verge can be dragged back onto the track, reducing the need for imported materials.

2. Drainage Management

Water is the enemy of any road surface. Pooling water exacerbates existing damage and creates new problems. If the existing roadway does not sit proud of the surrounding ground, drainage channels must be excavated along the sides. These can be simple earth ditches, but for a more durable solution, French drains, incorporating gravel and land-drainage pipes, are recommended. A critical aspect of the final surface is the implementation of a camber, or cross-fall, which ensures that surface water quickly drains into these channels.

3. Deep Ripping

Once the surface is cleared and drainage is addressed, the track undergoes deep ripping. This is typically carried out using a heavy-duty ripper, often with multiple legs. The ripper’s primary function is to break up the compacted surface and bring useful stone from deeper within the track’s construction to the surface. Over time, this process can unearth surprising items, but most commonly, it reveals usable stone, concrete, or tarmac. The ripper also loosens the hard edges around existing potholes, a key factor in preventing water from pooling and leading to their reformation. This stage is demanding on machinery, requiring regular replacement of wear parts like ripper points and potentially stressing components like auto-reset springs.

4. Crushing and Material Processing

This is arguably the most transformative stage of the reclamation process. A specialized crusher, fitted with numerous tungsten-carbide hammers, pulverizes the ripped-up material into fine, usable road-building aggregate. The crusher breaks down stones, concrete, and tarmac of various sizes into a consistent material. As it works, the crusher naturally segregates the material, pushing larger particles towards the base and allowing finer material to settle on top. Multiple passes may be made, with grading in between, to achieve the desired consistency. If a finer finish is required, the ripper can be employed again to bring more material to the surface for crushing.

5. Levelling, Shaping, and Stabilisation

With the material crushed and processed, the next step is to level and shape the track. Graders, either tractor-mounted for smaller adjustments or larger excavators for significant material movement, are used to create an even surface. During this stage, the crucial camber is introduced to ensure effective water runoff. Further passes with the crusher can refine the surface finish. Water may be added from a bowser to suppress dust and aid consolidation.

For enhanced durability and a longer-lasting surface, cement can be incorporated. This is spread evenly across the surface using a specialized hopper and then mixed into the full depth of the track (typically 10-12 inches or 25-30cm) using the crusher. Adding water from a bowser creates a finish akin to a concrete road, significantly increasing the track’s strength and longevity. The typical rate for cement stabilisation is around 1 tonne for every 10 metres of track.

6. Compacting

The final stage of the physical work involves compacting the newly formed surface. This is achieved using a tractor-mounted vibrating plate or a vibrating roller, which makes several passes to consolidate the material. Proper compaction is essential for creating a dense, stable surface that will resist wear and the formation of future defects.

7. Bedding In and Ongoing Maintenance

Once the physical work is complete, the track needs a period to fully settle and bed in. This typically takes a couple of months. During this crucial bedding-in period, it is vital to drive on the track at sensible speeds, especially on corners. Aggressive acceleration, harsh braking, and erratic driving can compromise the new surface before it has fully stabilised. Furthermore, repeatedly driving in the same wheel tracks can create channels where water can pool, eventually leading to the formation of ruts and potholes. Therefore, varying wheelings is essential to ensure the entire surface is compacted evenly and integrates properly.

What About Potholes?

Potholes are a persistent challenge for unmaintained tracks. Their compacted edges and bases tend to trap water, meaning that any material added to fill them is often quickly displaced or washed away. While attempts to repair individual potholes by ripping up their edges can sometimes exacerbate the problem, the beauty of the road reclamation process lies in its holistic approach. By ripping up and crushing the entire surface, existing potholes are eliminated, and a uniform surface is created, significantly reducing the likelihood of them reforming.

Cost Considerations

The cost of road reclamation can vary depending on the extent of the work required and whether additional materials or stabilisation methods are needed. As a general guide:

Q2: What is the lifespan of a reclaimed track?

With proper reclamation and the potential addition of cement stabilisation, a reclaimed track can offer a significantly extended lifespan, often rivalling or exceeding that of a conventionally laid surface. Regular maintenance and sensible usage are key to maximising its longevity.

Q3: Can road reclamation be done in wet weather?

While some aspects of the process can be carried out in light rain, heavy or prolonged wet weather can hinder certain stages, particularly those involving compaction and the effectiveness of cement stabilisation. It is best to consult with the service provider regarding optimal weather conditions for your specific project.

Q4: Is road reclamation environmentally friendly?

Yes, road reclamation is an environmentally friendly process as it prioritises the recycling and reuse of existing materials, significantly reducing the need for quarrying and transporting new aggregate. This minimises the carbon footprint associated with road construction and maintenance.

Q5: What is the difference between road reclamation and resurfacing?

Road reclamation involves breaking down and reprocessing the existing track material to create a new surface, often without importing significant amounts of new material. Traditional resurfacing typically involves laying a new layer of material (like tarmac or gravel) on top of the existing surface, which may or may not have been repaired first.
