In July 2015, a significant infrastructure project was carried out in Kolga-Jaani, involving the stabilization of a gravel-surfaced test road section. The goal of the project was to improve the quality and durability of the road segment by ensuring a dust-free, stable, and sufficiently strong surface capable of withstanding local traffic loads. In the second year, the road section was treated with a bitumen emulsion and crushed stone surface (a so-called chip seal), and in the fourth year, a 4 cm thick asphalt layer was added.<\/p>\n

StabilRoad Holding has continuously monitored the condition of the road segment over the past 10 years. As part of this monitoring, core samples have been taken from the road surface every two years to assess changes in the compressive strength of the stabilized soil through laboratory testing. The results show an average increase in compressive strength of 1.0 to 3.0 MPa over the ten-year period\u2014an exceptionally positive outcome. Visual inspections confirm that the appearance of the stabilized road surface has remained unchanged compared to its original condition. Based on current assessments, the same level of stability and strength is expected to persist for the next 50 to 100 years.<\/p>\n
