The need to protect natural mineral deposits used in the production of road aggregates requires the reuse of materials existing in existing surfaces. A specific example of the policy of reusing materials is obtaining them from asphalt granules from existing mineral and asphalt layers and using it to produce a new mineral and asphalt mixture. The use of asphalt granules reduces the consumption of new aggregates and reduces the amount of new asphalt used in the mixture. Unfortunately, the asphalt contained in the granulate has different properties than the new asphalt added in the production of a new mixture. In order to assess the impact of asphalt granules on the properties of the new asphalt mixture, it is required to conduct both laboratory and field observations and tests. The paper presents the results of research carried out at the research site, the aim of which was to observe two sections with surfaces that differ in their asphalt layer. An asphalt mixture made of new materials (the so-called reference mixture) and a mixture containing 40% of reclaimed asphalt were observed. In research, among others: Fiber optic sensors were used to measure deformations in mineral and asphalt layers.
