Current Research
- Scrap rubber tire in asphalt concrete. The main objective of this
research is to find a friendly use for vehicle rubber tires waste
in paving materials. This may, on the other hand, improves the properties
of asphaltic concrete. The research involves testing program of
asphalt concrete with different percentages of crumb rubber waste.
The testing program includes conventional as well as residual and
resilient characteristics.
- Retrofitting concrete structural elements using fiber reinforced
plastic. The technology of fiber reinforced plastic in construction
has been emerging in the past two decades. One important application
is the repair of concrete structural components which have been
exposed to overstraining, earthquake, overloading, etc. The research
is aimed at establishing the feasibility and the concepts of the
repair technique. It involves basic experimental program on cylindrical
elements and stressed beams. Theoretical analysis will be conducted
to better understand the empirical observations.
- Air entrainment in concrete is recommended for many applications,
principally to improve the resistance of concrete freezing and thawing.
However, there are other important benefits of entrained air in
both fresh and hardened concrete. In this research, concrete and
mortar are tested at different air contents for two conditions:
when water-cement ratio was maintained constant and when slump was
kept the same. Beside traditional testing, the testing program includes
permeability tests according to Cermann method, abrasion tests and
chemical durability tests using different salt solutions and acids.
- SUPERPAVE technology application. Roads in Egypt represent a major
portion of the nation's infrastructure affecting the varied activities
of the society on a day-to-day basis. Thus, rationalizing
the design and maintenance of roadways has a major effect on the
welfare of the public. The current methods used in designing and
building roads in Egypt lack the necessary technology that is needed
for a cost-effective infrastructure. The Egyptian infrastructure
can greatly benefit from the recent technology developed in the
U.S. in the area of highway engineering such as the SUPERPAVE technology.
The SUPERPAVE technology has been recently developed as part of
a U.S. Research project named Strategic Highway Research Program
(SHRP). SUPERPAVE research was highly focused on development of
pragmatic products of immediate use of highway agencies. The main
goal of the research project is to investigate the applicability
of the SUPERPAVE technology in Egypt.
