A Conventional Road

Road construction using Consolid soil stabilisation
Soil stabilisation using Consolid offers massive benefits during road construction. There is no need to change the design of the road. All the project work remains the same. Only the construction material in the subbase and base course is changed.
The CONSOLID soil stabilisation system deals with the in-situ soil. The soil behaviour changes dramatically
because it keeps the softening effect of water out of the treated soil.
The plate bearing pressure, e.g. CBR, increases substantially up to 3 to 5 times
compared with the untreated soil and in more than 50% of applications, plate
bearing pressure is more then 5 times higher.
Through the fact that the in-situ soil is used, there is no need to carry all
the soil of the embankment away and replace it with costly prepared material
from another place. Also the thickness of wearing course is reduced to 3 to 5
cm.
In our experience, the CONSOLID soil stabilisation system speeds up the road construction of about 1 km a day, it saves you 20% to 50% of the construction cost and it saves you in the future costs for maintenance. |

Have
you ever seen anything like that?
In 1975
a heavy-duty road was built in South Africa with CONSOLID and CONSERVEX,
using in-situ soil material. The road was in use during 5 years without
any repair work done, nor required, carrying a total load of about 5
mio. tons of coal. Subsequently it was abandoned 15 years ago and replaced
by a railroad. In spite of not being used for 10 years, when the photo
was taken, the road has not decayed and does not oven show signs of grass
or shrub growth. Usually nature takes over such roads within months.

Since soil once treated
remains treated and can be reused any time, it was planned to rip off
the road and reapply the treated material some place else. However, the
soil had turned to mineral concrete, so that the tooth of the ripping
equipment were not able to rip open the soil layer - they merely scratched
its surface. The pictures show this attempt at rousing the material performed
In 1990 - and the permanence of a soil treatment with the CONSOLID soil stabilisation system. |

Heavy Haulage Road made of 80% in situ sand + 20% clay.
A soil mix of 80% of the in-situ sea sand made cohesive by adding 20%
clayey soil was the base of this road; other construction material cannot
be found locally. The finally compacted, treated soil mix layer got a
pavement of 1. 5 " hot asphalt mix.

HOLLAND: REHABILITATION OF AN ASPHALT ROAD; Length: 3,5 km, 12'250 m2 at
Kraayensteinsedijk, Sommelsdijk by Rasenberg Wegenbouw BV
The worn asphalt road, in part positioned on a dike, had to be
rehabilitated. The existing embankment of the subbase and base courses is
upgraded with the CONSOLID soil stabilisation system in two thirds of the length in 300 mm
depth and one third of the length, 400 mm deep.
Thorough mixing has been done by three passes of the mixer to achieve the
desired homogeneous treatment.
The treated, compacted embankment received a new pavement by applying 5 cm
STAB mix 0/16 mm and 3 cm SMA toping 0/11 mm. Construction time for the
whole 3.5 km road was done in only three days. |
