REMARKS
Swelling soils, also known as expansive soils,
are ones that swell in volume when subjected to
moisture. These swelling soils typically contain
clay minerals that attract and absorb water.
When water is introduced to expansive soils, the
water molecules are pulled into gaps between
the soil plates. As more water is absorbed, the
plates are forced further apart, leading to an
increase in soil pore pressure (Handy, 1995). If
this increased pressure exceeds surcharge
pressure (including the weight of the overlying
pavement) the soil will expand in volume to a
point where these pressures are once again in
balance. Swelling pressures can be on the order
of 100 – 200 kPa (14.5 – 29 psi) and have been
measured as high as 1000 kPa (145 psi). Table
1 gives a general idea of the types of expansion
that can be expected.
