The deflection on roads is a fundamental parameter that provides valuable information about the structural capacity of the pavement. This indicator measures the bending or deformation that the road surface experiences under the application of a load. Essentially, deflection reveals the strength and load-bearing capacity of the pavement, being crucial for assessing its integrity and durability.
To measure deflection accurately, specialized equipment such as the FWD (Falling Weight Deflectometer) and the HWD (Heavy Weight Deflectometer) is used. These devices apply controlled loads to the road and measure the pavement's response, recording the amount of deflection that occurs. This data is essential for evaluating the structural capacity of the pavement and planning maintenance and rehabilitation interventions.
In summary, the deflection parameter, measured with equipment like FWD and HWD, plays a crucial role in assessing the structural condition of roads, allowing highway authorities to make informed decisions to ensure effective maintenance and prolong the lifespan of the road infrastructure.
