👉Segregation in Asphalt Roads

1. Definition:

🚧Segregation in asphalt roads refers to the separation of coarse aggregates from the finer materials within the asphalt mix.

This leads to areas of the road surface that have a non-uniform texture, which can affect the structural integrity and durability of the pavement.

2. Causes of Segregation

- Improper Mixing: If the asphalt mixture is not thoroughly mixed, larger aggregates may separate from the finer particles.

- Poor Handling and Transportation: During transportation or handling, the heavier aggregates might settle, causing uneven distribution.

- Inadequate Laying Techniques: If the asphalt is not laid evenly or is spread too quickly, segregation can occur.

- Compaction Issues: Inconsistent compaction can result in areas with varying densities, leading to segregation.

3. Effects of Segregation:

- Reduced Pavement Strength: Areas with segregation are often weaker and more prone to cracking and other forms of damage.

- Increased Water Permeability: Segregated areas allow more water to penetrate, which can lead to further degradation of the pavement.

- Rough Surface Texture: Segregation can cause an uneven surface, leading to discomfort for drivers and increased wear on vehicles.

4. Solutions to Prevent and Address Segregation: 

- Proper Mixing: Ensure that the asphalt mix is properly blended to achieve a uniform consistency before laying.

- Careful Handling and Transportation: Transport the mix in a manner that minimizes the settling of aggregates. Use proper loading and unloading techniques.

- Controlled Laying Procedures: Lay the asphalt mix at a consistent speed and thickness to avoid segregation. Use proper spreading and paving techniques.

- Effective Compaction: Use consistent and appropriate compaction methods to ensure uniform density across the pavement.

- Inspection and Quality Control: Regularly inspect the mix during production and before laying. Implement quality control measures to identify and address potential issues early.

- Corrective Measures: For existing segregated areas, corrective measures such as milling and overlaying or surface treatment can be used to restore uniformity and strength.

▶️Addressing segregation promptly can significantly enhance the lifespan and performance of asphalt roads, reducing maintenance costs and ensuring safer driving conditions.

👉Causes of foundation failure and removal measures

🚧Poor Ground Preparation

▶️Cut and fill situations should be properly prepared before the structure is started or it may result in improperly compacted soil beneath the foundation.

🚧Transpiration

⏺Vegitation, such as trees, shrubs, or other plants, near a foundation can affect moisture levels.

▶️Tree roots can dehydrate the soil beneath a home causing soil shrinkage and settlement of the home.

▶️Site clearance ላይ 20cm top layer ላይ ያሉ organic materials በደንምብ  ማስወገድ ምክንያቱም organic property of soil affects engineering properties of the soil

🚧Drainage

⏺Improper drainage will lead to excess moisture build-up, which could erode or consolidate soils.

▶️Excessive moisture may cause heaving of expansive clay soils.

⏺Remedial measure is proper drainage and compaction

🚧Poor Building Site Preparation

⏺Cut and fill situations, where the soil is removed from part of the building site and stacked on another, needs proper soil stabilization before a structure is built; otherwise unexpected movements of the soil beneath the foundation may occur.

🚧Poor Ground Preparation

▶️Cut and fill situations should be properly prepared before the structure is started or it may result in improperly compacted soil beneath the foundation.

🚧Poor Soil Conditions

⏺Poor soil, organics.....etc., may cause expansion or consolidation, which contribute to foundation failures.

▶️Using the correct foundation repair system can counteract the above conditions.

⏺Steel piers and helical piers are often the solutions for your basement or foundation.

👉Every Quantity Change a Variation?

🚧According to the FIDIC 1999 Red Book

🏷The Simple Answer is No.

▶️Sub-Clause 13.1: Right to Vary Pursuant to this Sub-clause the Engineer has been given the right to initiate a Variation at any time prior to issuing the Taking-Over Certificate.

However, not all quantity changes will necessarily constitute a Variation. The specific events where changes are recognized as Variations are detailed under Sub-Clause 12.3.

▶️Sub-Clause 12.3: Evaluation of Variations Pursuant to this sub-clause, scenarios where changes in quantities can lead to rate adjustments or be considered variations are detailed.

💫Specifically, it outlines the following conditions for such changes.

• Change Exceeds 10% : In case the measured quantity of an item changes by more than 10% from the Contract Bill of Quantities.

These changes are being considered for rate adjustments. Significant deviation can be a cause for a variation.

• Cost Impact Exceeding 0.01%:If the Cost of a variation(Changes in Quantity) exceeds 0.01% of the Accepted Contract Sum.

This threshold ensures that even minor changes with significant financial implications are evaluated for possible rate adjustments.

• Cost per Unit Changes by More than 1%: In case of the quantity changes are affecting to the cost per unit of the item by more than 1%, this event is considered as a variation and cause for a contract rate adjustment.

• Non-Fixed Rate Items: Quantity changes for the Items which have not been stated as “fixed rate item”, can be considered as a variation and Contract rate adjustment is acceptable.

🚧The FIDIC 1999 Red Book's approach to handling quantity changes through Sub-Clauses 12.3 and 13.1 provides a balanced mechanism for managing Variations and rate adjustments.
