Road Construction

The Mandev team is well-versed in the complexities and demands of road construction, bringing a wealth of experience to every project. With a proven track record in delivering high-quality roadways, the team excels in all aspects of the construction process, from initial planning to final execution.

Sub-base Construction

Material Selection: Choose appropriate sub-base materials, typically consisting of crushed stone, gravel, or other aggregates.
Layering: Spread and compact the sub-base material in layers, usually 4 to 8 inches thick, ensuring each layer is adequately compacted before adding the next.
Quality Control: Regularly test the sub-base material for density, moisture content, and compaction to ensure it meets design specifications.

Base Course Construction

Material Placement: Place the base course material, typically made of crushed aggregate, on top of the sub-base.
Compaction: Compact the base course to provide a strong and durable foundation for the asphalt or concrete pavement. The thickness of this layer varies depending on the road design.
Grading: Ensure the base course is graded correctly, with appropriate slopes for drainage.

Surface Course Construction

Prime Coat (for asphalt roads): Apply a prime coat, usually bitumen or tar, to the base course to bind the base and surface layers together.
Asphalt Paving (for asphalt roads): Lay and compact the asphalt surface course in one or more layers, depending on the road design. This is typically done using paving machines and rollers.
Concrete Paving (for concrete roads): Pour and level the concrete surface course, followed by finishing, curing, and joint cutting to allow for expansion and contraction.

Curing (for Concrete Roads)

Curing: Ensure that the concrete pavement cures properly to achieve the required strength. This may involve covering the surface with a curing compound, wet burlap, or plastic sheeting to retain moisture.
