Chemical stabilisation is the mixing of various chemicals into the pavement and not just the mere spraying of chemicals to the surface of the road.
The action of chemical binders in the pavement and subgrade materials are
|Adhesion:||Act as a glue in bonding particles|
|Adsorption:||To attract atmospheric moisture to reduce dust emission|
|Dilatant||To dispel water when compacted under vibration|
|Dispersant||Separates fine particles from each other|
|Ionic||Bonding from a reversing of the electrostatic charge on some soil platelets|
|Surfactant||To reduce surface tension.|
