| 总结: | Depression or bump that occurs between end of bridge approach slab and
road pavement interface always arises a great concern among motorists. The
occurrence of the bump that motorist feel as they leaves or approaches the bridge is
caused by the differential settlement problem. This problem becomes more apparent
particularly over soft soil condition such in Batu Pahat district. Currently, there is no
guideline and specification provided by the Public Work Department in designing a
proper bridge approach model, which has exceptional transition toward road
pavement. The current conventional model used in many projects was reported to be
less effective since the problem is still noticeable and it requires regular maintenance
work when the problem reappears recurrently. Practically, it is clear that the problem
is still unresolved and this is due to the complexity of the design problem itselfthat
merge the structural and geotechnical perspectives in design. The studies on
simulation modelling for approach slab and road pavement design also have been
rare. It is essential since such design analysis, which is based on numerical analysis,
could have advantages in providing preliminary expected outcomes for the modelling
purpose. In conjunction to this matter, the modelling of several approach slab and
road pavement concepts have been successfully conducted to verify the result
expectancies using this approach in order to provide better understanding on the
recurrent problem.
