Edge breaking in road pavement, also known as edge cracking or edge raveling, occurs due to several factors:

1. Insufficient Shoulder Support: If the road shoulders are not properly constructed or maintained, the edges of the pavement are unsupported and more prone to breaking under traffic loads.

2. Erosion: Water runoff can erode the soil supporting the pavement edge, leading to a loss of support and subsequent breaking.

3. Traffic Load: Vehicles, particularly heavy trucks, traveling close to the edge of the pavement exert significant stress on the unsupported edge, causing it to crack and break.

4. Poor Drainage: Inadequate drainage allows water to accumulate at the pavement edges, weakening the subgrade and base layers, leading to edge failure.

5. Narrow Roads: Roads that are too narrow force vehicles to drive close to the edge, increasing the stress and likelihood of edge breaking.

6. Vegetation: Roots from nearby plants and trees can grow underneath the pavement, disrupting the support and causing cracks and breaks at the edges.

7. Freeze-Thaw Cycles: Similar to other pavement issues, freeze-thaw cycles can cause expansion and contraction at the edges, leading to cracks and breaking.

8. Aging and Wear: Over time, the materials at the pavement edge can degrade and lose their structural integrity, making them more susceptible to breaking.

Regular maintenance, proper shoulder construction, adequate drainage, and managing vegetation near the roadway can help prevent edge breaking in road pavements.

The foundation depth of skyscrapers is a critical aspect of their structural design, as it determines the stability and safety of the building. The depth of the foundation for a skyscraper depends on various factors, including the height of the building, the type of soil and bedrock below the site, local building codes, and environmental conditions.

For tall buildings, especially skyscrapers, deeper foundations are usually required to ensure the structure can distribute the weight of the building safely to the ground. There are different types of foundations used for skyscrapers, including shallow foundations like spread footings or mat foundations, as well as deep foundations like piles or caissons.

In some cases, skyscrapers are built on sites with challenging soil conditions, such as soft clay or loose sand, which may necessitate even deeper foundations to reach more stable soil or bedrock layers. Engineers and architects work together to conduct thorough geotechnical investigations to determine the optimal foundation design for the specific site conditions.

The foundation depth of a skyscraper is a crucial consideration during the planning and construction phases to ensure the building's long-term stability and safety. Deep foundations are designed to transfer the loads from the building to the ground in a way that prevents settlement or excessive movement, thereby ensuring the structural integrity of the skyscraper.

Retaining walls are structures that are built to hold back soil or other materials and prevent them from sliding or eroding. There are many reasons why retaining walls may be necessary, such as:
- To prevent a slope from collapsing.
- To create level ground for a building or other structure.
- To create a raised garden bed or other landscape feature.
- To divert water away from a structure or area.
- To support a driveway or other paved surface.
- To create a barrier between two different types of soil.
