Type 1 Subbase

Testing to assess the compliance of Type 1 subbase against Highways England specification

Type 1 subbase is one of the most common materials used in pavement and road construction. It has a specific constitution and to ensure you obtain the benefit of these it is important that the material complies with several mechanical, physical and chemical properties.

At Hixtra we can test for the full suite of properties including particle size, abrasion, soundness, sulphate levels, plasticity and frost heave.

Recycled Type 1

This has additional test requirements which we can provide including assessing its constituent particles

Sampled from anywhere in the UK

The sample is critical to a representative test result so we can do the sampling for you.

Cases of dispute

We can also sample from existing laid material to assess it compliance
