A variety of resources have been generated during the course of the project, designed to be of use to different audiences. These cover publications and deliverables produced as the project progressed, scientific papers and training materials for end users.
Project Deliverables
-
This document (D2.1) provides an inventory of good practice and makes recommendations for approaches that can be adopted by NRAs to accelerate their transition to circularity. It is based on the results of an extensive review of academic and industry literature, a questionnaire survey with follow up interviews of selected NRAs in Europe and workshop discussions with industry experts.

This document carries out the objectives outlined in Work Package 2, Task 2.2 of the CERCOM project. Accomplishing the task’s primary aim of facilitating the data collection necessary for developing the CERCOM Risk Based Assessment Framework (RBAF) in WP3 will require the completion of five key objectives, the results of which are described throughout this document:
- Establishing data requirements of WP3
- Mapping available data
- Evaluating available data quality
- Reviewing existing data management systems (DMS)
- Recommendations for integration of data across Asset Management systems (AMS)

Deliverable 3.1 encompasses the work performed as part of CERCOM Tasks 3.1 – 3.3 and delivers a roadmap to the application of the work carried out as part of these work packages. As such, this document details the stages involved in developing the Risk Based Analysis Framework (RBAF) as well as guidance on the application of the framework within current public procurement practices. A key part of this work is the development of KPIs used within the RBAF to aid the move from a linear to circular economy.

This report provides a detailed description of the Risk-Based Analysis Framework (RBAF) Software Tool developed as part of CERCOM Work Package 3 and Deliverable 3.2. The aim of the framework is to facilitate procurement of circular solutions for road construction and maintenance while assessing the risk of doing so.
For this project, it was essential to integrate circularity factors into procurement practices. However, when considering procurement, it is necessary to also consider more traditional criteria such as Performance, Cost, Environmental and Social factors. As such, the RBAF was developed to take account of all these factors. As with any tender evaluation, weight factors provided by the user are used to quantify priorities of each NRA for a specific project/scheme. The Software Tool not only considers performance but also the uncertainty associated with performance given the use of new or less proven materials or construction and production technologies. -
The major objective of this report is to demonstrate the validity of the Risk-Based Analysis Framework (RBAF) developed as part of the CERCOM project (in Deliverables D3.1 and D3.2) through technical case studies covering a range of pavement maintenance options. The steps associated with the quantification of risks in adopting a particular maintenance strategy such as life extension (R4), refurbishing (R5 or R6), and use of recycled materials (R8) were detailed. In addition, the different assessment categories that must be utilized to understand the circularity and sustainability potential of various strategies were elucidated along with the development of specific technical, environmental, economic, circularity, and social Key Performance Indicators (KPIs) relevant to the case studies examined as part of deliverables D4.1 & D4.2.

D4.3 presents the third of three case studies carried out in Work Package 4 and explores the practical implementation of RE and CE principles in the delivery of road infrastructure projects. The objective was to identify strategies adopted by NRAs to embed RE and CE thinking in their organisation and supply chain. The results are presented in two parts: section 2 presents an in-depth investigation of the approach adopted by the UK National Highways (NH) to make CE an integral part of road infrastructure management. Section 3 presents brief descriptions of five initiatives that are in early stages of development from 4 countries (UK, Netherlands, Ireland and Sweden) representing constituent aspects with potential to contribute to CE:
- Initiative 1: Resource exchange mechanism (UK) – (In1)
- Initiative 2: Circular road partner programme (NL) – (In2)
- Initiative 3: Sweating the pavement asset (IE) – (In3)
- Initiative 4: Living document / route map to energy reduction in tunnels (NL) – (In4)
- Initiative 5: Interactive decision support tool for climate action (SE) – (In5)
-
The major objective of this report is to present the feedback gathered from members of the participating NRAs and road construction and maintenance stakeholders on the various tools developed as part of the CERCOM project.
-
This aim of this document is to provide an overview of the developed material and to outline how and where the material can be accessed. The Resource Pack encompasses the developments and advances of the CERCOM project and provides resources that NRAs can use to implement the necessary changes towards the adoption of circular economy practices in road construction and maintenance.

Implementation of the circular economy and resource efficiency has the potential to significantly contribute to decarbonisation targets, while using fewer natural resources, maintaining or enhancing biodiversity and providing regenerative design for generations to come. The CERCOM project has developed an innovative risk-based framework and management tool to facilitate a step change in the adoption of Resource Efficiency (RE) and Circular Economy (CE) principles in procurement and multi-lifecycle management by National Road Authorities (NRAs) across Europe.Original publication here >
Resources for road authorities
The following information resources have been developed during the CERCOM project to help road authorities identify and adopt strategies that lead to greater resource efficiency:
-
01. Introduction to circularity and resource efficiency for road authorities
-
02. Good practice and case studies in improving circularity and resource efficiency
-
03. Framework for assessing progress in transitioning to circular economy
-
04. Interactive framework for assessing progress in transitioning to circular economy.
-
05. Introduction to KPIs and data for monitoring resource efficiency
-
06. Introduction to the risk based assessment framework (RBAF) for evaluating circular maintenance options
-
07. Principles and functionality of the RBAF software
-
08. RBAF software
-
09. RBAF user manual
-
10. Demonstration of the RBAF software
-
11. Case studies in the application of the RBAF
These CERCOM case studies will test the validity of the risk-based approach developed in WP3 over a range of technical areas (new material applications, recycling, and innovative technologies) at different levels of development and maturity.
A sensitivity analysis will be undertaken to evaluate the robustness of the model results, identify the model boundaries (sensitivity to uncertain parameters), and assess the availability and reliability of the input data. The analysis of the case studies will uncover the difficulties and highlight the opportunities for the implementation of RE & CE principles.
