Cement concrete modular pavements, also known as precast concrete pavements, designed for pedestrian and bicycle paths is the advanced next-generation technology characterised as high quality, durable, quickly built and easily maintained. Polypropylene fibre reinforced concrete mixture is more frequently used to improve the properties of concrete slabs and to reduce thickness. The thickness of the slab could be reduced to 8–10 cm using the appropriate fibre. This paper focuses on the selection of slab dimensions and verification of fibre reinforced concrete mixture production method when fibres are added to the factory-made concrete mixture (available from the concrete plant) and evaluation of different surface texture of concrete slabs produced by using special texture mats. Seven different combinations of concrete slabs have been developed, constructed and tested in 21 m length pedestrian pathway in Vilnius city. The analysis of mechanical and surface characteristics of these slabs are presented in this paper. The research revealed that the most suitable (pendulum test values ≥ 55) surface texture for the pedestrian pathway is formed by using texture mats.
