Problems in Construction of Roads

Release time：2025-10-26    Click：50

　　Various factors are responsible for the lifespan of roads and pavements. Persistent potholes and recurrent ruts are constantly wreaking havoc on roadways. Further environmental factors, traffic loads, road widening, age of roads, subgrade soil conditions are all factors that affect the service life of roadways.

　　Primarily, the detrimental factors affecting roadways are the temperature extremes, poor drainage, substrate composition, and wear and tear. It is ideal to address these issues and problems either during initial construction or rehabilitation for better outcomes.

　　Pavement distress and degradation are primarily attributed to permeability, with surface water infiltrating, softening, and weakening the subgrade.

　　When the subgrade consists of clays, silts, or silt, it retains moisture and tends to shift and expand with freeze/thaw cycles, thus resulting in roadbed deterioration. While on the other hand, sandy, well-drained soil adds years to the lifespan of roads.
