- Design speed: the speed at which vehicles are expected to travel
- Curve radius: the sharpness of the turn
- Road surface: the type of pavement and its frictional characteristics
- Vehicle characteristics: the type of vehicles using the road and their dynamic properties

⭐️Types of Super Elevation;

There are two main types of super elevation:

- Linear super elevation: a constant rate of banking along the curve
- Parabolic super elevation: a varying rate of banking along the curve, with the maximum banking at the midpoint

⭐️Importance of Super Elevation;

Super elevation is a critical component of road design, as it directly affects the safety and comfort of drivers. Well-designed super elevation can:

- Reduce the risk of accidents
- Improve traffic flow
- Enhance driver comfort and safety
- Increase the overall safety of the road

📜Conclusion;

In conclusion, super elevation is a vital element in road design, requiring careful consideration of factors such as design speed, curve radius, and road surface. By providing a safe and comfortable driving experience, super elevation plays a critical role in reducing the risk of accidents and improving traffic flow.

👉The Ethiopian Roads Authority (ERA) has specific standards for compaction degrees in road construction, ensuring optimal performance and durability. These standards typically vary depending on the layer type and material properties.

💫General Guidelines:

* Subgrade: 95-98% of the maximum dry density (MDD) as determined by Standard Proctor or Modified Proctor test.
* Subbase: 95-98% of the MDD, similar to the subgrade.
* Base Course: 98-100% of the MDD, requiring higher compaction for load-bearing capacity.
* Capping Layer: 95-98% of the MDD, depending on the material used and its function within the pavement structure.

💫Factors Influencing Compaction Degree:

* Material Type: Different materials have varying compaction characteristics.
* Layer Thickness: Thicker layers may require more effort to achieve desired compaction.
* Moisture Content: Proper moisture content is crucial for optimal compaction.
* Equipment Type: The type of compaction equipment used can influence the achievable density.
* Traffic Load: Higher traffic loads may necessitate higher compaction degrees in lower layers.
Importance of Compaction:
* Stability: Adequate compaction provides stability and resistance to deformation under traffic loads.
* Durability: Well-compacted layers contribute to the overall durability of the pavement structure.
* Drainage: Proper compaction can improve drainage characteristics, reducing the risk of water damage.
* Uniformity: Consistent compaction ensures uniform support for the overlying layers.

⭐️ERA Standards:

For precise and up-to-date compaction requirements, it's essential to refer to the specific ERA standards and specifications applicable to the project.

These documents will provide detailed guidelines based on the latest research and industry best practices.

By adhering to these standards, road construction projects in Ethiopia can achieve high-quality pavements that are safe, durable, and resilient to the challenges of the local environment and traffic loads.

👉African Development Bank renews and expands agreement to use FIDIC standard contracts for a further five years

🏷FIDIC has renewed and expanded a major agreement with the African Development Bank Group that will now see the multilateral development bank employ ten FIDIC standard contracts for the next five years. The bank is the leading source for development financing in Africa and is committed to supporting inclusive and sustainable growth and good governance across the continent.

📜Under the terms of the agreement, FIDIC has granted the bank a non-exclusive license to refer to ten major FIDIC contracts for projects they finance and the documents will be used in the bank’s main standard bidding documents. The list of contracts now includes reprints of the 2022 FIDIC Rainbow Suite, the latest FIDIC Green Book 2021 and the reprint of Emerald Book 2023 contract for Underground Works and the Dredgers contract 2016.

⏺The suite of contracts covered by the agreement with FIDIC covers a wide range of international construction and infrastructure work.

⏺The Bank’s initiative represents a further key endorsement for FIDIC contracts from a major international funding organisation, following similar agreements signed with the World Bank and many other multilateral development banks around the world.

💫FIDIC president Catherine Karakatsanis MESc PEng FCAE ICD.D LL.D D.Eng said: “I am delighted that the AfDB has renewed and expanded its agreement with FIDIC to be used as an accepted form of contract for use with their standard bidding documents. As well as this being another major development for FIDIC, we hope that this move will create more certainty in the market, as by facilitating the use of FIDIC contacts on major projects the AfDB is saying that they endorse the fair and balanced approach that these documents offer to parties on major construction contracts.

“We know that the certainty FIDIC contracts bring makes it easier to get projects underway, as many of the common commercial risks are clearly addressed in the contracts and all parties understand their obligations and responsibilities. FIDIC looks forward to the AfDB’s continuing endorsement of these contracts providing additional reassurance to the financial, institutional and private equity investors operating in the global market to adopt the use of FIDIC standard procurement contracts as an effective tool to mitigate the risks associated with major infrastructure projects and assets.”

⏺Commenting on the signing of the agreement, Frank Mvula, director, fiduciary and inspection department at the African Development Bank, said: “We are glad to have concluded this agreement that will enable us to incorporate FIDIC contracts in our main standard bidding documents.

⏺There is no doubt that the use of the internationally recognised FIDIC contracts is a step towards enhancing equity and economy, as well as efficient and effective contract management, as emphasised under the bank’s procurement framework. We look forward to working with FIDIC for another five years.”

👉How is a reinforcement bar in hardened concrete structure exposed to corrosion?

💫ሙሉ በሙሉ ጥንካሬውን ያገኘ የ ኮንክሪት ስትራክቸር ውስጥ ያለ ወይም የተሰራበት reinforcement bar እንዴት ሊዝግ ይችላል? በምን ምክንያቶችስ ሊሆን ይችላል?

🏷3 መሰረታዊ የሆኑ ሁኔታዎች reinforcement ባራችንን በበቂ ሁኔታ ጥንካሬውን ባገኝ የ አርማታ ስትራክቸር ውስጥ ባለበት ሊያዝጉት ይችላሉ (corrosion እንዲፈጠር ሊያደርጉት ይችላሉ)

⭐️1. የመጀመሪያው carbonation ይባላል

⏺እንደሚታወቀው concrete strongly alkaline nature አለው። ይህም የሆነበት ምክንያት Ca(OH)2 ስላለው።

⏺pH value ደግሞ about 13 ነው። 

▶️due to this high alkalinity nature ኮንክሪቱ reinforcement ባሩን ከ corrosion ለመከላከል a thin passivating layer በባሩ ዙሪያ በመፍጠር ብረቱን ከዝገት ይከላከላል። ይህም process passivation በመባል ይታወቃል።

▶️As we know CO2 በራሱ reactive አይደለም። ግን in the presence of moisture( እርጥበት) ወደ dilute carbonic acid ይቀየራል። ከዛም concrete form ያደረገውን passivating layer መብላት ወይም ማፈራረስ ይጀምራል። በመጨረሻም PH value ን  ወደ 8.3 - 9 ያደርሰዋል። ልክ PH value ከ 11 ማነስ ሲጀምር ብረቱ በቀላሉ መዛግ ይጀምራል።

🏷2. ሁለተኛው ደግሞ chloride attack ነው

⏺በተመሳሳይ መንገድ ልክ carbonation passivating layer ን ማፈራረስ እንደሚችል chloride attack ም ያንን በበለጠ ማድረግ ይችላል።

▶️chloride attack is more serious reason than any other
▶️in the presence of water and oxygen, chloride can destroy the passivating layer and leads to corrosion.
▶️chloride በቀላሉ ወደ ኮንክሪቱ ሊገባ ይችላል።

⚡️ለምሳሌ በ cement,water,aggregate and sometimes from admixtures or from environment by diffusion.

🏷3. ሶስተኛው በ electrochemical process ነው

⏺ይሄኛው ደግሞ when there is a difference in electrical potential along the steel reinforcement in concrete.

⏺ብረቱ ውስጥ አንደኛው part anode ሌላኛው part ደግሞ cathode ሲሆን ነው።

👉Calculating Maximum Dry Density (MDD) and Optimum Moisture Content (OMC) of Coarse Aggregate for Base Course On Road Construction

💫Understanding MDD and OMC

🏷Before we delve into the steps, let's clarify what MDD and OMC signify:

* Maximum Dry Density (MDD): This is the highest density a soil can achieve in a controlled laboratory environment under specific compaction efforts.
* Optimum Moisture Content (OMC): This is the moisture content at which a soil reaches its maximum dry density under those same compaction efforts.
Why are MDD and OMC important?
* Achieving Adequate Compaction: By knowing the MDD and OMC, engineers can ensure that the soil used in the base course of a road is compacted to its maximum potential, leading to a more durable and stable road structure.
* Preventing Over-Saturation: Compacting soil that is too wet can lead to excessive water content, which can weaken the soil and reduce its load-bearing capacity.
* Ensuring Proper Drainage: If the soil is too dry, it can be difficult to compact properly, and it may not be able to effectively drain water, which can lead to frost heave and other problems.
Steps to Determine MDD and OMC
The standard method for determining MDD and OMC is the Proctor Compaction Test. Here's a simplified overview of the process:
* Sample Preparation: A representative soil sample is collected and prepared according to standard laboratory procedures.

* Moisture Content Determination: A portion of the soil sample is oven-dried to determine its natural moisture content.
* Compaction: The remaining soil sample is divided into several portions, each with a different moisture content. Each portion is placed in a cylindrical mold and compacted using a standardized hammer and number of blows.
* Bulk Density Calculation: The weight and volume of each compacted soil sample are measured to calculate its bulk density.
* Dry Density Calculation: The bulk density is then converted to dry density by accounting for the moisture content.
* Plotting the Compaction Curve: The dry density values are plotted against their corresponding moisture contents to create a compaction curve.
* Determining MDD and OMC: The peak of the compaction curve represents the maximum dry density (MDD), and the corresponding moisture content at this peak is the optimum moisture content (OMC).
Visual Representation:
Key Considerations for Coarse Aggregates:
* Modified Proctor Test: For coarse-grained materials like those used in base courses, the Modified Proctor test is typically used, which involves a heavier hammer and more blows than the Standard Proctor test.
* Field Compaction: The MDD and OMC values obtained from the laboratory test serve as targets for field compaction. Field density tests are performed to ensure that the actual compaction achieved in the field meets the specified requirements.

⏺By following these steps and understanding the significance of MDD and OMC, engineers can ensure that the base course of a road is constructed with the optimal moisture content and maximum density, leading to a more durable and long-lasting pavement structure.

👉What is the Difference Between Beam and Lintel ?

🏷Beams and lintels are both horizontal structural members used in construction, but they serve distinct purposes and have some key differences:

💫Beams

⏺Function

* Primarily used to support vertical loads over long spans.
* Transfer loads from floors and roofs to columns and walls.

⏺Location:

* Typically run parallel to the length of the building.
* Can be found in various locations within the structure, including floors, roofs, and basements.

⏺Span:

* Generally have longer spans compared to lintels.

💫Lintels


⏺Function:

* Specifically used to support the weight of masonry (bricks, stone, etc.) above openings like doors and windows.
* Transfer the load to the sidewalls of the opening.

⏺Location:

* Positioned horizontally above openings in walls.

⏺Span:

* Have shorter spans, typically spanning the width of an opening.

❇️In essence:

* All lintels are beams, but not all beams are lintels.
* Lintels are a specific type of beam with a specialized function and location within a structure.

👉Concrete roads are a very expensive choice in the desert for several main reasons:

💫1. The cost of the raw materials :

Concrete needs high-quality materials, such as cement that is resistant to salt, sand, and lime, which increases cost compared to asphalt roads.

💫2. A special design to withstand desert conditions:

To ensure concrete resists cracking and corrosion due to heat and sand, expensive components such as fibers and chemical additives are added, as well as designing more complex extension spacers.

💫3. Transport costs:

Desert project sites are often far from material sources, resulting in a significant increase in transportation costs.

💫4. THE NEED FOR A STRONG FOUNDATION :

Sand soil in the desert requires a strong and stable foundation, which adds an extra cost to the preparatory work.

💫5. Long term maintenance:

Although concrete roads last longer, the cost of maintaining them in a harsh desert environment is high due to the need to periodically address erosion and cracking.

💫6. The cheaper alternatives:

Asphalt driveways are considered significantly less costly to build and maintain, making them the most common choice in desert areas, unless the need requires long-term infrastructure.

⭐️High cost makes concrete roads a less attractive option in desert projects, unless the goal is to invest in an infrastructure that lasts for decades without the need for major changes.

👉What is Asphalt Road Construction?

🚧Asphalt road construction: involves the use of asphalt, a mixture of aggregates, binder, and filler, to build and maintain roads, highways, and other pavement surfaces.

🏷The components of asphalt include aggregates, binder, and filler. Aggregates are the inert materials that provide strength and bulk to the asphalt mixture.

⏺Common aggregates used include crushed rock, sand, gravel, or slags.

The binder is the adhesive substance that holds the aggregates together, with bitumen being the most common binder used.

Fillers are fine materials that fill the gaps between the aggregates and binder, such as limestone dust, cement, or hydrated lime.

The asphalt mixture is created by combining the aggregates, binder, and filler in specific proportions. The mixture is then heated to a high temperature (around 300°F) to facilitate mixing and application.

The asphalt road construction process typically involves several steps. First, the site is prepared by clearing the area, removing debris, and grading the surface. Next, a layer of compacted aggregate material is laid down to provide a stable base.

The heated asphalt mixture is then applied to the base course using a paver or spreader.

After the asphalt mixture is applied, it is compacted using rollers or compactors to achieve the desired density and smoothness. Finally, the surface is finished with a layer of asphalt emulsion or sealcoat to protect it from the elements.

Asphalt road construction is used for a wide range of applications, including highways and roads, parking areas, railway tracks, ports and airport runways, bicycle lanes and sidewalks, and playgrounds and sports areas.

Asphalt is a popular choice for road construction due to its durability, flexibility, and resistance to heavy traffic and harsh weather conditions.
