Base Build-up Course - Tarmac

Open Grade Tarmacadam Resin Bound Base Build Up For Domestic Driveways

It is important to understand the base that you are working with before planning your Resin Bound system. This guide is to help you understand the Tarmac base course.

This base course is permeable and therefore SUDS compliant

Purpose:

To provide an attractive, durable and seamless natural stone or gravel finish. 

Advantages:

An attractive and durable surface that allows water to pass through the surface and is easy to clean. 

Further Information:

  • Resin Bound can be overlaid onto existing macadam surfaces of suitable construction for the traffic expected. Joints or cracks should be broken out to a minimum of 200mm depth and filled in with well-compacted macadam base layers as above.
  • We always recommend the use of a geotextile membrane or ground stabilisation membrane. A ground stabilisation membrane helps maintain the stability of the subbase as the membrane prevents stone from migrating into the subsoils.

Important

The specification is based on normal good practice for flexible surfacing and does not absolve the specifier from designing a construction suitable for the expected traffic and ground conditions pertaining on a given site. Areas that may be heavily trafficked by heavy vehicles should have structure layers designed according to DoT requirements.

The thickness of the sub base layer required is dependent on sub grade soil conditions.

Actual details should be developed by the project designers taking into account the specific circumstances of the intended application.
