Microasphalt

Our Microasphalt process is a cold applied low carbon alternative compared to conventional surfacing treatments.

The process offers the use of a range of versatile materials, depending on the clients' specifications. Bitutex, Bitumac, Ralumac 1000, Ralumac 2000 and Ralumac HT (High Texture)all offer unique engineering and application benefits.

Colas' Microasphalt Surfacing treatment is accredited to the National Sector Scheme 13b and ISO 9001.

Depending on the materials specified Microasphalt can be utilised on Carriageways, Airfields and Car Parks.
Using bespoke plant and equipment; all materials are combined in-situ and applied on any given surface. The range of materials offered allows the filling of any ruts and deformations in a single pass.

The design of the application provides a reduction in traffic noise, improved appearance and skid resistance and a high resistance to rutting. Through forming a protective sealant over the existing surface, reducing deterioration of the existing surface and increasing skid resistance the process offers clients enhanced durability and a uniformed finish.

Bitutex

Bitutex is a high quality slurry surfacing ideal for roads and car parks where it provides a clean, dense sealed surface as an alternative to surface dressing or as a pad coat.

Bitutex offers

• Excellent adhesion to a wide variety of surfaces
• Enhances durability
• Resistance to the ingress of water and potential frost damage
• Trafficable within 15-20 minutes

Bitumac

Bitumac is ideal for use where a hard wearing and longer lasting surface is required. Suitable sites include urban and rural roads, which are subjected to greater levels of traffic.

Bitumac offers 

• Improved skid resistance
• Uniformed finish
• High performance
• Resistance to the ingress of water and potential frost damage
• Reduced traffic noise
• Trafficable within 20 - 30 minutes

Ralumac

Ralumac is a cold applied polymer modified treatment suitable for a wide variety of sites particularly appropriate for restricted sites with limited access and high speed sites with heavier levels of traffic.

Ralumac offers

• Longer life expectancy
• The ability to fill ruts and deformations in a single pass
• High resistance to rutting
• Reduced traffic noise
• Reduced site occupation

Ralumac 2000

Ralumac 2000 is a cold applied 0/6mm wearing course which incorporates a polymer modified bitumen emulsion and cellulose fibres, fibreglass can be added as a SAMI to reduce the effect of reflective cracking, with high quality aggregates.

Ralumac 2000 offers

• Ideal for high traffic volumes and speeds
• Enhanced laying capacity
• Greater resistance to cracking
• Meshtrack can be used to provide greater strength and durability

Ralumac HT

Ralumac HT is a cold applied surfacing designed and developed by Colas Ltd. The material specification has been enhanced and Ralumac HT also incorporates the use of cellulose fibres. Fibreglass can be added as a SAMI to reduce to reduce the effect of reflective cracking.

Ralumac HT offers

• Ideal for high traffic volumes and speeds (BBA HAPAS Approved)
• High texture finish and quality
• Greater strength and durability
• High resistance to rutting

Benefits

• Versatile surfacing treatment
• Cold mix properties reduce energy consumption and carbon emissions
• Resolves wheel track rutting and deformations
• Specialist machines carry all the components of the treatment and can complete them in a single pass Double Coat Application
• Low noise characteristics
• Can withstand heavily trafficked roads and principle routes
• Uniformed and sealed finish.

Footway maintenance

For footway maintenance we offer footway slurry and Fibredec. Our footway slurry treatments are Bitutex FP, Paveseal and Pavecoat .

Bitutex FP is a rapid setting hand applied slurry surfacing, hand applied the cost effective treatment consists of a blend of bitumen emulsion and aggregate, mixed to specific proportions.

Paveseal is apremium fibre enhanced slurry surfacing suitable for sites which require regulating and for the refurbishment of worn concrete surfaces.

Pavecoat is a cold applied, polymer modified, fibre enhanced slurry surfacing suitable for sites with significant levels of deterioration. Pavecoat can be applied to all types of asphalt, macadam and worn concrete surfaces.

Fibredec consists of a matrix of chopped glass fibres between two layers of bitumen emulsion. The surface is immediately dressed with aggregate. The glass fibres, which are chopped in situ be specifically designed applicator vehicles, give tensile strength to the surface and resist cracking.
