Methods and compositions for the installation of scientifically engineered and constructed unpaved runways are disclosed herein. The compositions are heterogeneous mixtures produced by blending aliphatic or cyclic organic compounds with binders that chemically react with gravel, aggregate, and soil particles to create permanent bonds, resulting in a strengthened and stabilized surface. When blended into the aggregate of a runway surface, the organic compounds act as a carrier fluid, distributing the binder system evenly so particles of all sizes are thoroughly and uniformly coated with the composition. Once the composition is distributed, an adhesion promoting compound reacts with constituents in the aggregate to increase the formation and strength of chemical bonds between particles.
