Flexible Pavement is the Cheapest in Initial Stage of Construction

Flexible pavement is the cheapest in the initial stage of construction compared to other types of pavements. The following are the reasons why:

1. Lower Cost of Materials:

Flexible pavements are made of materials that are readily available and cost-effective. The materials used in the construction of flexible pavements include bitumen, aggregates, and filler materials. These materials are affordable, and their costs are relatively low compared to other pavement types.

2. Lower Installation Costs:

Flexible pavements require less labor and equipment during installation, which makes them cheaper to install. The construction process involves spreading the bituminous binder on the prepared surface and then placing the aggregate on top. This process is simple and straightforward, requiring minimal equipment and labor.

3. Lower Maintenance Costs:

Flexible pavements require less maintenance compared to other types of pavements, which makes them cheaper in the long run. The maintenance of flexible pavements involves sealing cracks and potholes, which is less expensive than repairing rigid pavements.

Conclusion

In conclusion, flexible pavements are the cheapest in the initial stage of construction due to the lower cost of materials, installation, and maintenance. However, it is essential to note that the durability and lifespan of flexible pavements are relatively shorter than rigid pavements, which can lead to higher maintenance costs in the long run.
