Given:
- Moisture content of soil at borrow area = 14%
- Moist unit weight of soil = 17 kN/m³
- Specific gravity of solids for soil = 2.7
- Finished compacted volume = 2000 m³
- Dry unit weight of compacted soil = 18 kN/m³
- Moisture content of compacted soil = 16%
- Capacity of dump truck = 150 kN
To find:
i) Number of trips required to transport soil to the construction site
ii) Amount of water in kN to be added to borrow soil to achieve desired compaction
Solution:
1. Calculation of Dry Unit Weight:
The dry unit weight of soil can be calculated using the following formula:
Dry unit weight (γd) = Moist unit weight (γ) - (Moisture content (w) × Unit weight of water (γw))
Given:
Moist unit weight (γ) = 17 kN/m³
Moisture content (w) = 14%
Unit weight of water (γw) = 9.81 kN/m³ (approximate value)
Substituting the values:
γd = 17 - (0.14 × 9.81) = 17 - 1.3734 = 15.6266 kN/m³ (approximate value)
2. Calculation of Water Content:
To calculate the water content, we need to find the weight of water present in the soil. The weight of water can be calculated using the following formula:
Weight of water = (Moisture content (w) × Dry unit weight (γd) × Volume)
Given:
Moisture content (w) = 16%
Dry unit weight (γd) = 18 kN/m³
Volume = 2000 m³
Substituting the values:
Weight of water = (0.16 × 18 × 2000) = 5760 kN
3. Calculation of Amount of Water to be Added:
To achieve the desired compaction, we need to add water to the borrow soil. The amount of water to be added can be calculated using the following formula:
Amount of water to be added = Weight of water required - Weight of water present
Given:
Weight of water required = 0 (since the desired moisture content is already given)
Weight of water present = (Moisture content (w) × Dry unit weight (γd) × Volume)
Substituting the values:
Weight of water present = (0.14 × 15.6266 × 2000) = 4393.84 kN
Amount of water to be added = 0 - 4393.84 = -4393.84 kN
4. Calculation of Number of Trips:
To calculate the number of trips required to transport the soil, we need to divide the total weight of soil by the capacity of the dump truck.
Total weight of soil = Dry unit weight (γd) × Volume
Number of trips = Total weight of soil / Capacity of dump truck
Given:
Dry unit weight (γd) = 18 kN/m³
Volume = 2000 m³
Capacity of dump truck = 150 kN

- Moisture content of soil at borrow area = 14%
- Moist unit weight of soil = 17 kN/m³
- Specific gravity of solids for soil = 2.7
- Finished compacted volume = 2000 m³
- Dry unit weight of compacted soil = 18 kN/m³
- Moisture content of compacted soil = 16%
- Capacity of dump truck = 150 kN
To find:
i) Number of trips required to transport soil to the construction site
ii) Amount of water in kN to be added to borrow soil to achieve desired compaction
Solution:
1. Calculation of Dry Unit Weight:
The dry unit weight of soil can be calculated using the following formula:
Dry unit weight (γd) = Moist unit weight (γ) - (Moisture content (w) × Unit weight of water (γw))
Given:
Moist unit weight (γ) = 17 kN/m³
Moisture content (w) = 14%
Unit weight of water (γw) = 9.81 kN/m³ (approximate value)
Substituting the values:
γd = 17 - (0.14 × 9.81) = 17 - 1.3734 = 15.6266 kN/m³ (approximate value)
2. Calculation of Water Content:
To calculate the water content, we need to find the weight of water present in the soil. The weight of water can be calculated using the following formula:
Weight of water = (Moisture content (w) × Dry unit weight (γd) × Volume)
Given:
Moisture content (w) = 16%
Dry unit weight (γd) = 18 kN/m³
Volume = 2000 m³
Substituting the values:
Weight of water = (0.16 × 18 × 2000) = 5760 kN
3. Calculation of Amount of Water to be Added:
To achieve the desired compaction, we need to add water to the borrow soil. The amount of water to be added can be calculated using the following formula:
Amount of water to be added = Weight of water required - Weight of water present
Given:
Weight of water required = 0 (since the desired moisture content is already given)
Weight of water present = (Moisture content (w) × Dry unit weight (γd) × Volume)
Substituting the values:
Weight of water present = (0.14 × 15.6266 × 2000) = 4393.84 kN
Amount of water to be added = 0 - 4393.84 = -4393.84 kN
4. Calculation of Number of Trips:
To calculate the number of trips required to transport the soil, we need to divide the total weight of soil by the capacity of the dump truck.
Total weight of soil = Dry unit weight (γd) × Volume
Number of trips = Total weight of soil / Capacity of dump truck
Given:
Dry unit weight (γd) = 18 kN/m³
Volume = 2000 m³
Capacity of dump truck = 150 kN
