The paper discusses the use of Polypropylene Fiber Reinforced - Latex Modified Mortar (PFR-LMM) for installation of granite paving blocks (GPBs) on various road sections in Slovenia. The following four examples are considered: two inner rings of roundabouts on both sides of the bridge over the Sava River on the bypass near Krško, a roundabout in front of the entrance to the Šoštanj thermal power plant and one part of a street in Ljubljana. GPBs were installed on a slab made with Steel Fiber Reinforced Concrete (SFRC). The workability of the fresh PFR-LMM had to be such that it filled the joints between the GPBs. Hardened PFR-LMM, however, must provide a good bond between the GPBs to ensure resistance to traffic loads and resistance to constantly changing weather and temperature influences. The age of the subject applications is between 5 and 11 years.
