The research
discusses roads rehabilitation using foamed bitumen,which is a
relatively new method and hasn’t been used in Syria yet due to the
lack of the needed labrotory equipments ,and that’s why the main
aim of the research is to develop a mo
del to stimulate the labrotory
experiments needed to evaluate the performance of the rehabilitated
pavement (surface deflection – strain ). The model was developed
using the finite elements method with the help of ABAQUS
modelling software.
In this research, we present, a linear programming using model.
This model can define the optimal proposal ( with minimum cost
and high efficiency ) in both cases : new net design or exist net
modification.
This research introduce the public-private partnership (PPP), by determine the
difference between the types of PPP contracts, and lighting on the most important
experiences of main countries to identify responsibilities of each part of contract.
I
n order to study the possibility of using PPP in Syria, within the crisis since (2011).
To afford additional resources of funding, to improve the development process of
infrastructure projects, especially projects that related to the energy sector, specifically
electricity sector.
The electricity sector is one of the most sectors exposed to destruction, and it was the
first goal of any sabotage carried out by terrorists. this sector suffering by is more than 430
billion Syrian pounds loses, since the start of the crisis until the end of 2015, and this
amount is nominated to rise by the time according to many reasons, one of this reasons is
exchange rates fluctuations risk.
The amount ofdamages is very huge number, comparison to the size of funds that
dedicated by the government to finance investment. On the other hand, there is a serious
need to additional resources of funding, to finance the development and rehabilitation
process of infrastructure projects. Therefore, could the PPP provide these resources? That
is what the research is looking for.
This research related to the reappointment of the main roads and railways in the
event of loss (Axis elements in the horizontal projected: Straight lines. Circular curves.
Between these two elements are introduced Transit Curves), and also rehabili
tation,
commensurate with the developments taking place in the present time. The program is
designed to also facilitate this work using the language of MATLAB.
There are several questions present themselves:
- What are the requirements for work (Field or desktop)?
- What are the proposals for the development of the current reality of the road
network and railways in the study area and rehabilitation?
- What are the tools that allow transfer of theoretical study to a realistic work
progress on the ground?
