Using GISUsing GISObjective
The objective of the project is to predict the soil series along the route SH 130 that are presumed to heave after lime stabilization.

Using GISUsing GISOverview
A pavement surface course is generally one of the two forms: Portland cement concrete or asphalt concrete.
Lime stabilization comes into picture when the
subgrade soil is very soft.
The problem of heaving is common when sulfate is present in the subgrade soil.
A secondary mineral called ETTRINGITE is formed under favorable conditions.
