Throughout the world, concrete, the backbone of the infrastructure development of a nation, is
being widely used for the construction of most buildings, bridges, etc. And cement which is
ingredient of concrete has ...
Concrete strength depends on the quality of concrete-making materials selection. The
concrete-making materials selection should satisfy the requirement stated in the standards.
Mixing and curing water is one of the ...
Concrete, as the world’s most implemented construction material, is increasingly being used
because of the rapid development of industrialization and urbanization. Limited resources and
progressive depravation of the ...
In the present scenario, no construction activity can be imagined without concrete. To make
concrete using mix of three ingredients; aggregates, cement, and water are usual. Many
structures show premature and excessive ...
Concrete is one of the most widely used construction materials in the world.it is a heterogeneous
composite material consisting of cement, water, fine aggregate, and coarse aggregates. The
binder of coarse aggregate ...
In the present scenario, due to less availability of space and more population, in multi-storey
buildings (both residential and commercial) an open space is reserved for parking, assembly
hall or for auditorium purposes ...
The structural composite construction techniques find increasingly wide applications in bridges,
ramp, buildings and other different area throughout the world focusing on the composites systems.
Composite structures ...
Urban traffic is growing from day to day following a high demand along the roads. This traffic
growth contributes a bottleneck at bridge approaches with constricted widths. In Jimma town,
vehicles passing the town are ...
Currently, a huge amount of reclaimed asphalt pavement is produced each year worldwide due to different
reasons. These materials are generated when asphalt pavements are removed for reconstruction,
resurfacing, or to ...
Traffic accidents which has happened at the signalized intersections are one of the locations that the crashes
used to occur compared to the roundabouts and any other roads because it is intersection. Nowadays, it’s the ...
The structural behavior of pavements can be affected by seasonal variation in
environmental factors such as temperature and moisture content. In Ethiopia the design,
construction and maintenance process of roads mostly ...
Ethiopia’s highway network showed that a high percentage of roads are suffering from fatigue,
creep, and rutting in the long term. These stresses may have occurred due to the shortage in the
mechanistic properties of ...
One of the inputs for the economic development of a country is the expansion of the road
network, which is important for the transportation of people and freights from place to place.
With this expansion, the occurrences ...
The properties of clayey soils can be problematic due to the damage it can bring to civil
engineering structures such as roads, buildings and others infrastructures. This is because the
clayey soil swell when contact ...
Expansive soils are the most abundant soils in the world, and in Ethiopia, this expansive soil
covers more than 40% of the total land area. Road construction along in such types of soils
causes significant damage to ...
The road pavement construction industry of consumes a large amount of virgin aggregate and Solid
waste material has impacts on environmental problem. Therefore, this investigation aims to explore
the suitability of ...
Asphalt concrete road construction is now an important aspect of Ethiopia's growth and
transformation plan for developing a high-performance transportation network to support the
country's economic development. Aggregate, ...
Filler, as one of the components in asphalt mixtures, plays an effective role in their properties and
behavior, especially regarding binding and aggregate interlocking effects. Mineral fillers and
different aggregate ...
Expansive soils mostly cause significant damage to structures such as buildings, pavements and
bridges. Therefore, the objective of this study was to quantify the improvements achieved on the
weak subgrade soil strength ...
Expansive soils have considerable volume changes, which related to the change in its moisture
content. The sudden change of the volume in the expansive soil can cause major damages to the
overlying structures such as ...
