This Best Practice Guide has emerged from a working group (Pavement Foundations Group) to address the need for consistency in the implementation of LWD’s into UK practice. However, the guide does reflect best practice for a range of applications. It describes the industry best practice for using Lightweight Deflectometers to verify the construction quality of road foundations. The guide is seen as a statement of current knowledge, and includes recommendations for site operations. It is expected that this guidance will be updated periodically
