ROAD SOIL STABILIZATION
THE PROBLEMS OF
UNSEALED ROADS: Many unsealed roads do not have the ideal
range and distribution of particle sizes to give a good
load bearing capacity when wet (coarser particles) or
sufficient plastic capability (clay) when dry to prevent
material from breaking loose. All gravel roads, when dry
suffer some surface abrasion loss resulting in dust
because, the adhesion between the particles is reduced.
Loose material on the road causes dust that blows away or
washes away under heavy rain. Over time, the amount of
fine binding soil in the road is reducedand gradually more
and larger particles break away. The loose surface becomes
prone to increased dust, pot holes and corrugation, making
the road uncomfortable and dangerous to drive upon.
The properties of the soil beneath the road structure are
mainly concerned. These soil properties, which influence
the ability to support load, are determined by the
presence of clay minerals. Swelling and shrinkage of clay
due to interaction with water causes serious failure like
cracking, rutting, depression and subsidence. The
properties and behavior of clay in fact depends on the
amount and type of constituent minerals. Ongoing
maintenance is expensive,and in time the fines are lost
and the road deteriorates faster requiring more regular
maintenance. To solve those problems, PCN has applied and
treated the road with Soil
Stabilization.
Why Road Soil
Stabilization ?
Reduce Construction Cost for NEW Roads
Reduce Maintenance Cost for EXISTING roads
Key Benefits
Increased Bearing Capacity
Increased Soil Workability
Long term Stabilization
Reduces re-adsorption of Water
Reduces gravel loss
Increase traficability in wet condition
Soil stabilization
products as an alternative to paving road is relatively
newtechnique of deeply mixing chemical additives into
unpaved roadbeds. The benefits of soil stabilization is
cost, endurance and repair ability. This work is based on
the 1 km long trial installation at the coal loading ports
in Batu Licin where stabilization products were applied to
the unpaved road
(Note: PCN has also
successfully applied soil stabilization to the access road
of palm oil plantation prior to treating the hauling coal
road with soil stabilization for trial installation).
A rigorous evaluation of road treatment performance
provided the basis for recommendation to the major hauling
coal road regarding improvements to the maintenance
practices for gravel roads. Results thus far indicate that
the introduction of soil stabilizers through deep mixing
is promising and providing cost-effective than maintaining
an unpaved road. Therefore, the purpose of this work was
to ascertain the feasibility of deeply mixing particular
soil stabilization materials into unpaved roadbeds with
the intent of maximizing the intervals of time between
required maintenance activities.
Road Soil Stabilization is not new technologies, but they
are relatively new to Indonesia. With road maintenance
costs rising and out of control for moststates, towns and
municipalities in these difficult economic times, combined
with the severe impact of this past years winter,
Environmental Construction Technologies has the right
solution at the right time.
With a new breakthrough in environmentally friendly soil
stabilization
construction technologies, we can save the road budget 50%
or more over asphalt and cement road resurfacing. With our
line of RP Soil Stabilization Systems, we can convert any
type of road soil composition into a high quality
completely waterproof surface that will significantly
reduce your construction and maintenance costs.
Soil Stabilization is non-toxic and environmentally safe.
