How many meters apart are highway expansion joints?

[AdamRose]

Highway expansion joints are spaced every 10-15 meters. Below are detailed explanations about highway expansion joints: 1. Definition: An expansion joint, also known as a construction joint, is a structural gap designed to prevent building components from cracking or being damaged due to climate-induced temperature changes (thermal expansion and contraction). It is set along an appropriate part of a building or structure's construction joint direction. Expansion joints divide building components above the foundation, such as walls, floors, and roofs (excluding wooden roofs), into two independent sections, allowing the building or structure to expand and contract horizontally along its length. 2. Function: To prevent buildings from cracking due to climate changes. The method involves leaving gaps at regular intervals along the length of the building, completely separating all above-ground components like roofs, walls, and floors. The building foundation, being buried underground and less affected by temperature changes, does not need to be separated. The width of expansion joints is generally 20 to 30 millimeters, filled with thermal insulation material. The spacing between two expansion joints is clearly specified in building structural codes.
