The area of ​​Hrvatsko Zagorje (i.e. Croatian upland) is the most prone to landslides in the Republic of Croatia, with landslides occurring practically every day, caused either by natural or anthropogenic factors. Many of these landslides are activated along the network of state and local roads that pass through numerous cuttings mostly without any or with inadequate slope stabilization measures. Implementation of investigation works, design and rehabilitation works are all accompanied by numerous challenges. Designing effective landslide remediation measures requires a thorough understanding of geological, hydrological, and environmental factors influencing slope stability. This paper presents investigation works and rehabilitation design of a road landslide in Hrvatsko Zagorje in Croatia, where the landslide occurred downhill slope of the road.
