Testing & Technical Data
We ensure that our recycled aggregates are tested against and comply with the relevant European Standard, as well as national specifications (Highways England SHW). All of our testing is carried out at independent UKAS accredited laboratories and the results are available to customers on request.
We hold a comprehensive library of technical data from our third-party suppliers for all quarried and dredged natural aggregates that we supply. For more information please contact our Technical department.
As of 1st July 2013, under the Construction Products Regulations (CPR) 2011, it became mandatory for manufacturers to draw up a Declaration of Performance (DOP) and apply CE marking to any of its construction products that are covered by a Harmonised European Standard (HEN).
Materials such as Specification for Highway Works Clause 803 Type 1 and Specification for Highway Works 600 Series Capping, and fill materials do not require CE marking as they are not harmonised at this time.
