# Stabilization of Road Embarkments on Peat Soils Using Oil Shale Ash and Pozzolanic Additives
## Results and Discussion
### Initial Tests in Nature  
Five samples were taken, the phase composition and mineral compositions of which are outlined in Tables 10 and 11. The formation of crystalline phases proceeds relatively slowly under swamp conditions, and amorphous phases still make up approximately half of the total mass after 4 months. \begin{table}
