Definitions and Examples

1. Asphalt: A mixture of dark bituminous pitch with sand or gravel, used for surfacing roads.
• The new road was covered in smooth, dark asphalt.
2. Bitumen: A black viscous mixture of hydrocarbons obtained naturally or as a residue from petroleum distillation, used for road surfacing and roofing.
• Bitumen is essential for waterproofing the new road.
3. Bulldozer: A powerful track-laying tractor with caterpillar tracks and a broad curved upright blade at the front for clearing ground.
• The bulldozer cleared the site for the new highway.
4. Cement: A powdery substance made by calcining lime and clay, used in building to make concrete.
• The workers mixed cement to prepare the foundation.
5. Concrete: A building material made from a mixture of broken stone or gravel, sand, cement, and water, which can be spread or poured into moulds and forms a stone-like mass on hardening.
• The bridge supports were constructed from reinforced concrete.
6. Construction: The building of something, typically a large structure.
• Construction of the new road is expected to take six months.
7. Contractor: A person or company that undertakes a contract to provide materials or labour to perform a service or do a job.
• The contractor was responsible for the entire road project.
8. Crane: A large, tall machine used for moving heavy objects by suspending them from a projecting arm or beam.
• A crane was used to lift the heavy concrete beams.
9. Culvert: A tunnel carrying a stream or open drain under a road or railway.
• The culvert was installed to prevent flooding on the roadway.
10. Curbstone: A long, narrow stone or concrete block, laid end to end with others to form a kerb.
• They placed curbstones along the edges of the pavement.
11. Drainage: The system or process by which water or liquid waste is drained from an area.
• Proper drainage is crucial to prevent waterlogging on the roads.
12. Earthwork: Engineering works created through the moving and processing of quantities of soil or unformed rock.
• The earthwork for the new road involved significant excavation.
13. Embankment: A wall or bank of earth or stone built to prevent a river flooding an area.
• The road was built on an embankment to elevate it above the floodplain.
14. Engineer: A person who designs, builds, or maintains engines, machines, or structures.
• Engineer Musa supervised the construction of the bridge.
15. Excavation: The process of digging up the ground to prepare a site for construction.
• The excavation revealed a layer of solid rock.
16. Grader: A machine with a long blade used to create a flat surface during the grading of roads.
• The grader smoothed the gravel surface of the road.
17. Gravel: A loose aggregation of small water-worn or pounded stones.
• The path was covered with gravel to improve traction.
18. Intersection: A point where two or more roads meet.
• Traffic lights were installed at the intersection to manage the flow of vehicles.
19. Kerb: A stone edging to a pavement or raised path.
• Pedestrians are advised to walk on the pavement and stay within the kerb.
20. Lane: A division of a road marked off with painted lines and intended to separate single lines of traffic according to speed or direction.
• The highway was expanded to include an additional lane.
21. Levelling: The process of creating a flat or even surface.
• The levelling of the site was completed before construction began.
22. Machinery: Machines collectively or the components of a machine.
• Heavy machinery was used to clear the land for the new road.
23. Maintenance: The process of maintaining or preserving someone or something, or the state of being maintained.
• Regular maintenance ensures the longevity of the road.
24. Marking: A sign or symbol made on a surface to indicate something.
• Road markings were applied to guide drivers.
25. Median: A strip of land between the lanes of opposing traffic on a divided highway.
• Trees were planted along the median to enhance the road’s appearance.
26. Milling: The process of grinding or crushing a substance.
• The old asphalt was removed through milling before the new layer was applied.
27. Mixer: A machine for mixing things, especially an electric machine for mixing cement or concrete.
• The cement mixer churned continuously to prepare the concrete.
28. Paving: The act of covering a surface with flat stones or bricks.
• The paving of the road was completed ahead of schedule.
29. Pedestrian: A person walking rather than travelling in a vehicle.
• Pedestrian crossings were added to improve safety.
30. Paver: A machine that applies asphalt or concrete to form roads.
• The paver evenly spread the asphalt over the road surface.
31. Pavement: A raised paved or asphalted path for pedestrians at the side of a road.
• The new pavement was wide enough to accommodate wheelchairs.
32. Piers: Vertical supports for a bridge or other structure.
• The bridge piers were reinforced to ensure stability.
33. Pile: A long, slender column typically driven into the ground to support a structure.
• The construction crew drove piles into the riverbed for the new bridge.
34. Planning: The process of making plans for something.
• Careful planning is essential for successful road construction.
35. Pothole: A depression or hollow in a road surface caused by wear or subsidence.
• Potholes were filled to ensure a smooth drive for commuters.
36. Project: An individual or collaborative enterprise that is carefully planned and designed to achieve a particular aim.
• The road project is expected to boost the local economy.
37. Reconstruction: The action or process of reconstructing or being reconstructed.
• The reconstruction of the old road improved traffic flow significantly.
38. Resurfacing: The process of laying a new surface on an existing road.
• Resurfacing of the highway reduced the number of accidents.
39. Roller: A large, heavy machine used for flattening or compressing surfaces.
• The roller compressed the gravel to create a solid base.
40. Roundabout: A road junction at which traffic moves in one direction around a central island to reach one of the roads converging on it.
• A new roundabout was constructed to improve traffic management.
41. Safety: The condition of being protected from or unlikely to cause danger, risk, or injury.
• Safety measures were implemented to protect the workers on site.
42. Sand: A loose granular substance, typically pale yellowish brown, resulting from the erosion of siliceous and other rocks and forming a major constituent of beaches, riverbeds, the seabed, and deserts.
• Sand was used to create the base layer for the road.
43. Scaffolding: A temporary structure on the outside of a building, made of wooden planks and metal poles, used by workers while building, repairing, or cleaning the building.
• Scaffolding was erected to support the workers as they constructed the bridge.
44. Section: Any of the more or less distinct parts into which something is or may be divided or from which it is made up.
• The project was completed in several sections, each handled by different teams.
45. Sidewalk: A paved path for pedestrians at the side of a road.
• Sidewalks were added to ensure pedestrian safety.
46. Sign: An object, quality, or event whose presence or occurrence indicates the probable presence or occurrence of something else.
• Traffic signs were installed to guide drivers.
47. Site: An area of ground on which a town, building, or monument is constructed.
• The construction site was busy with activity.
48. Slab: A large, thick, flat piece of stone or concrete, typically rectangular.
• Concrete slabs were used to form the base of the road.
49. Soil: The upper layer of earth in which plants grow, a black or dark brown material typically consisting of a mixture of organic remains, clay, and rock particles.
• The soil was tested to ensure it could support the new road structure.
50. Structure: A building or other object constructed from several parts.
• The structure of the new bridge was designed to withstand heavy traffic.
