What Is The Construction Process Of A Concrete Road?
Concrete roads are built with a mixture of Portland cement, coarse aggregate, sand, and water. The most significant benefit of a Concrete Road is its long service life due to its outstanding resilience.
They are far less prone to wear and tear flaws such as rutting, cracking, stripping texture loss, and potholes that may occur on flexible pavement surfaces. One of the primary advantages of concrete pavements is their minimal maintenance demand.
Concrete pavements that have been well-designed have required little or no upkeep. Less maintenance also means fewer traffic delays, which greatly benefits some of our already overcrowded roadways.
The following steps are involved in the building of a concrete road:
- Subgrade preparation- formed and leveled. It is cleaned and then prepared to the desired grade and profile.
- Form placement- Forms are appropriately braced and staked to the ground. Before pouring concrete into the moulds, they are lubricated.
- Watering the Prepared Subgrade- After the forms have been installed, the prepared surface to receive concrete is moistened. It should be sprayed with as much water as it can absorb.
- Material Batching- the quantities of the elements for the concrete mix and the fine and coarse aggregates are appropriately balanced.
- Transporting and placing the concrete mix- the concrete is brought to the job site. The mixed concrete is quickly poured on the subgrade in a layer of thickness.
- Compaction- done with a strong screed or tamper with appropriate handles. Concrete is compacted using a power-driven finishing equipment, vibrating hand screed, and slabs screed vibrator.
- Floating- this is done to give a level surface devoid of corrugations.
- Belting- done soon before the concrete hardens.
- Brooming entails drawing brushes from edge to edge at right angles to the road’s centerline.
- Edging- The slab’s edges are meticulously polished with an edging tool before the concrete is set.
- Filling joints appropriately with a suitable sealing compound.
- Curing- preventing water loss from the concrete slab and keeping the fresh concrete slab wet during the hardening phase.
- Traffic opening after achieving necessary strength.
Conclusion
Concrete can bear large loads, such as big cars, with minimal deformation. It will last for years without requiring substantial maintenance. Traffic, soil, environmental, economic, and stress distribution considerations impact concrete pavement performance.
