ROAD CONSTRUCTION IN BOISE, ID

FROM ROAD EXCAVATION TO PAVING

Steps in the road construction process:

1. Planning: Road construction or expansion begins with a detailed planning phase. Our team of experienced professionals provides comprehensive assistance with project planning, drafting, and obtaining the necessary permits to ensure a smooth start.
2. Grubbing: Clearing the construction site is a significant task. All obstructions such as buildings, fences, and vegetation must be removed to create a clear path for the new roadway.
3. Excavation: After the site is cleared, heavy machinery is used to excavate the soil, creating a stable foundation for the road.
4. Grading: Proper grading is essential to ensure a solid base for the road and to facilitate adequate drainage. This final stage of site preparation is critical before the construction of the road’s layers begins.
5. Subgrade, Sub-base, and Base Layers: The road is built on a system of layers, starting with the subgrade and progressing to the sub-base and base. These compacted layers provide the foundational support needed to handle vehicle loads.
6. Binder Layer: This key middle layer transfers the load from the road's surface to the base, ensuring the road’s structural integrity.
7. Wearing Layer: The top layer, made from asphalt concrete, forms the visible driving surface and provides the road's characteristic appearance. 
8. Rigid Pavement: The rigid pavement acts as a load distributor, spreading pressure evenly across the road’s surface, prolonging its service life and minimizing strain on the subgrade.
9. Marking: Road markings such as lane lines are applied to guide traffic and enhance safety.
