Research Aim and Objectives
Aim: The aim of the research is to analyze by means of
case study, the construction efficiencyand durability of
decks with pre-cast, pre-stressed concrete deck planks
case study chosen has been paper is to discuss the
deck replacements that were carried out in 1999
Illinois Department of transportation. The case study analysis
considers the construction and early performance element for
the two deck planks. These bridge deck reaplcements
weredone by means of precast, prestressed concrete (PPC)
deck planks.
Research Objectives:
To identify by means of the case study the issues that
had existed for the original deck planks so as to
compare how prestressed and precast concrete deck
planks outrate.
To identify the early performance specifics of the
precaset prestressed concrete deck planks
To recommend based on case study analysis, the
and mean that precast, prestressed deck planks can add
to the durability of the deck planks
4. Literature Review
Precast and Prestressed Concrete Slabs:
Precast and prestressed concrete slabs are usually hollow
core clabs, these either have topping and are importatn
structural elements when it comes to indsutr
constructions [2]. Slabs are either prodcued by means of
casting beds or by means of using pretenisoning elements
There are various forms of pre-tensioning available.
They will be cut to more shorter span lengh
construction that is being planned out. In some cases they
would also be provided free support. Free support ensures
that there are transverse walls and beams between the
systems. There are different form of precast, pre tensioned
cored slabs used in practice. Some of the more popular ones
are that of the 2000 mm nominal width that has been used
with a lenght of 3.6 to 6.4 meters [9]. Economical hollow
cavities have been used as well alone with round cavity slabs.
