How To Use Soil Stabilization In Road Construction In 2019

Aug 21, 2019· Agglomeration of host soil particles leads to the larger effective grain sizes. Pozzolanic reaction results in cementitious materials, usually calcium silicate hydrate and calcium aluminate hydrate gels. These kinds of processes of soil stabilization in road construction are very time-dependent and can continue over a long period of time.
