RWS asked Boer & Croon to reassess the stakeholder analysis from 2019 and investigate how the Soil, Road, Engineering, and Hydraulic Engineering (GWW) sector views the transition towards sustainable road pavements. In doing so, Boer & Croon was asked to compile the input into a report and provide advice on ways in which the transition could be realised and accelerated.

Boer & Croon started with the recalibration of the stakeholder analysis that was conducted in 2019. The question had changed from whether a transition should take place to how the transition should take place. A new stakeholder analysis was compiled by interviews with asphalt plants, contractors, municipalities, provinces, universities, research institutions, and those responsible for RWS. This looked at each party's needs, confidence in achieving the objectives and their influence on the transition path. The content of the interviews was then used to compile a report and formulate recommendations to achieve and, where possible, accelerate the transition.

In addition to providing more insight into the current state of the sustainable road paving sector, Boer & Croon also provided a number of targeted and concrete recommendations at RWS's request that RWS can work on in 2024 and beyond.

Perhaps the most impactful is the advice to create a single joint platform where stakeholders in the sector can come together, conduct research, provide practical assistance and solutions for a successful transition and support answers to public and private stakeholders in the industry. In addition, through this platform - with the working name the Asphalt Expertise Centre (ECA) - subsidy, validation and certification of new mixtures and techniques can take place. In addition to the advice for the ECA, B&C has also written opinions on reducing the number of asphalt mixtures in the Netherlands and extending the service life through the applications of rejuvenation creams, both aimed at making the asphalt sector and Dutch society as a whole more sustainable.
