RWS has far-reaching ambitions in the field of sustainability. These ambitions can only be achieved

be realized if sustainable products, such as sustainable asphalt, can be used

within the works of RWS. Asphalt is one of the largest material flows at Rijkswaterstaat and

causes more than 30% of the CO2 emissions from RWS. Partly due to the establishment of the Transition Path

Sustainable Road Surfaces (to which the ITC contributes) RWS wants to ensure that this market this new

develops sustainable asphalt types and can then apply them. The requirement to be allowed to do so

is to be able to go through a successful validation process. The use of (test) knowledge

of TU Delft is necessary to be able to carry out these validation assessments properly. Within the

Transition path Sustainable Road Surfaces participate in a large number of components, in particular WVL, GPO,

PPO and the Region. The role of ITC (part WVL) is to supervise the (custom) validation

of innovative sustainable asphalts. Only after a successful conclusion
