Types of roadworks

Microasphalt

  • Economical and preventative surface treatment for roads
  • Great in urban areas

Microasphalt is an economical way of resurfacing roads which are starting to show the first signs of wear and tear. This is used when the structure of the road is good but the very top surface is beginning to wear and needs sealing to stop water getting in, preventing major deterioration. Treatments usually take place between May and September.

Patching

Patching is the process of removing the defected areas of the carriageway to provide a cost-effective maintenance method to extend the life of the road where it is needed.

Regen on-site recycling process

This process rebuilds the road by reusing as much of the existing material as possible, reducing waste and improving sustainability.

How it works:

  1. Investigation and testing - Engineers carry out surveys, including cores and trial holes, to understand the thickness and condition of the existing road and the strength of the ground below. Traffic levels, particularly heavy vehicles, may also be assessed.
  2. Breaking up the existing road - The road is broken up (pulverised) to a depth typically between 150mm and 200mm using specialist machinery. The material is left in place.
  3. Adding binding material - A cement-based powder is spread over the broken material.
  4. Mixing and strengthening - The material is mixed with water and the cement powder to create a strong, stabilised base layer.
  5. Sealing the surface - The new layer is sealed with either a surface dressing or a layer of asphalt. This prevents water from entering and protects the new road structure.

Resurfacing

Resurfacing is the process of removing the existing surface course, and in some cases base layers, of the full width of the carriageway. The carriageway is then replaced with a new layers of material to extend the life of the road and ensure it remains safe for use.

Re-texturing

Road re-texturing is a restoration treatment where the carriageway is blasted, with either high pressure water or small ball bearings, to restore surface texture. The process is low cost and is generally used on roads in a good condition which just need improvements to skid resistance.

Roadmaster

  • An effective and efficient road surface treatment
  • Great for rural roads

The Roadmaster is an all-in-one spray injection chip patching system requiring just one person.

It treats surface defects effectively - sealing the target area, filling cracking and removing potholes whilst regulating the surface. It produces a better finish and it reduces the likelihood of road repairs failing prematurely.

Surface dressing

Surface dressing is the most cost-effective way to prolong the life of roads that show minor signs of deterioration. It improves the road surface, skid resistance and seals the surface to stop water getting in. This protects it from damage caused by severe winter weather conditions and traffic.

A thin film of bitumen is sprayed on to the road surface followed by one or two layers of chippings. The chippings are then rolled into the bitumen to form an interlocking, long lasting surface.

We close the road to carry out the work, but it's completed quickly and can be driven on straight away under reduced speed limits (to protect road workers and the public, as well as reduce the risk of damage from loose chippings).

Surface dressing process:

  1. A thin film of bitumen is sprayed onto the road surface
  2. Layers of chippings are applied
  3. The chippings are rolled into the bitumen using a heavy roller to create a durable, long-lasting surface
  4. Loose chippings are swept away after 24 hours and again after four to five days

Once this process is complete, the road will reopen with a temporary 20mph speed restriction.

Thermal road repairs

  • A great way to use existing materials
  • Tackles potholes

We use heat to reform carriageways to a very high standard. The thermal heat process ensures surrounding areas are not damaged. The process does not require the full use of planers, tippers, bitumen sprayers or loaders which means less noise. Jointless repairs use 80 to 90% recycled materials that eliminate landfill waste and lower the carbon footprint of the repair.
