Would you like to contribute to the asphalt of the future as a laboratory technician? In our central laboratory, you will work on innovative asphalt mixtures that make the Netherlands more sustainable and circular. Not a sterile laboratory where your white coat stays spotless, but a practical environment in which you investigate construction materials, perform tests, and have a direct influence on the quality of roads and infrastructure.

Your job
As a laboratory technician, you will work in the central laboratory that supports the KWS branches and 6 asphalt plants. You investigate new construction materials, new asphalt mixtures, and conduct research to ensure mixtures can remain certified. In doing so, you do not work on a single standard product, but on hundreds of different asphalt recipes, each with its own properties and challenges.

Part of your work is investigating asphalt from ongoing projects or from the asphalt plants. When deviations are detected or specific research questions arise, you go in search of the cause. You perform tests independently, analyze results, and translate these into useful advice for colleagues and clients.

Additionally, you participate in innovation projects where new construction materials and raw materials are tested. Together with the team, you investigate whether these materials contribute to more sustainable asphalt, lower emissions, or a longer lifespan for roads. In this way, you contribute directly to the development of circular infrastructure and innovative applications within the infra sector.

You prepare test mixtures by collecting, weighing, and sieving construction materials and making large batches. In this, you work with specialized equipment such as a gyrator, compression tester, desiccator, and a large sawing machine. Within the team, you coordinate the planning and share results and the progress of the research.

You will join an expert and engaged team where colleagues help each other, share knowledge, and collaborate. Your day starts and ends at our central laboratory on the Bazeldijk in Hoogblokland, in the middle of the green polder. The laboratory is located on the same site as an asphalt plant. Because of this, we are directly connected to practice, and you can simply walk outside to collect your construction materials.
