Presented a complex case study corresponding to a road embankments
upto10m height placed at Iassy (Romania).
The analysis shows high strain and low bearing capacity for soils in
flooded state.

LGV EST section 41 : measured
and calculated settlements under
embankments

Six embankments are monitored to measure the settlements and the
time of consolidation.
The preconsolidation pressure of the soil is estimated from the
undrained cohesion C
u
and the coefficient of consolidation C
v
used in
the design was ten times the C
v
measured with laboratory test.
Influence of installation damage
on the tensile strength of asphalt
reinforcement products
Touole L.S. and
Thesseling B.
Germany
The effective tensile strength of asphalt reinforcement products,
considering installation damage was analysed.
A considerable difference in loss of tensile strength, due to the effects
of installation damage was observed.
Influence of Mechanical Indices
for Soil Basement on Strength of
Road Structure
Teltayev B.
Kazakhstan
Moisture value and its phase content in soil basement of the highway
vary substantially in annual cycle and according to the depth of
basement.
The maximum values of sagging, tensile stress and vertical deformation
of cement concrete pavement occur in summer and autumn seasons.

The CBR values indicated variations between 8% and 12%, which are
below the contract special specification minimum value of 15%. This
was therefore considered as having marginal quality for its intended
purposes.
Results obtained from the field evaluation indicated high CBR and
bearing resistance values including insignificant settlement.

To fulfill stability and settlement analysis, the road at Zone 1, and 3
should be strengthened by secant pile walls combined with raising of
0.7 m.
The road at Zone 2 should be strengthened by concrete sheet piles and
ground anchor.
Deformation Performance and
Stability Control of Multi-stage
Embankments in Ireland
Buggy F.J.
Ireland
Deformation ratios offer a reliable method for controlling stability of
multi-stage embankments when used in conjunction with pore pressure
instrumentation. For the specific conditions at Limerick Tunnel, a limit
deformation ratio of 0.6 was shown to give satisfactory performance
and acceptable stability.
Excessive lateral deformation related to local failure occurred at several
locations in the vicinity of creeks, ditches and historical excavations
located within 10 m of the embankment toe.
