The construction of embankments on weak and compressible soil deposits often results in soil consolidation and settlement due to the embankment’s weight. Factors such as the embankment’s height, the depth of the weak soil layer, and the soil strata’s consolidation properties can lead to significant settlements. These can create challenges for maintaining road evenness, functionality, and the long-term durability of the road structure.

By utilizing the lightweight properties of Leca LWA, these settlements can be significantly reduced or even eliminated. Furthermore, the aggregate’s excellent drainage capacity ensures long-term load stability, effectively minimizing the risk of structural failure or further settlement.
