Evaluating Strength, Interlocking, and Load-Carrying Performance of WBM Pavement Layers

Water Bound Macadam is carried out to evaluate the strength, aggregate interlocking, compaction characteristics, and load-bearing capacity of WBM layers used in road base and sub-base construction. Proper mechanical performance of WBM is essential to ensure a stable, durable foundation capable of supporting traffic loads and distributing stresses effectively to lower layers.

Why WBMMatters.

Ensures Proper Aggregate Interlocking

Mechanical testing verifies that coarse aggregates, screenings, and binding materials form a well-interlocked structure, which is critical for layer stability.

Verifies Strength and Load-Bearing Capacity

Testing confirms that the WBM layer can safely withstand anticipated traffic loads without excessive deformation or failure.

Assesses Compaction Quality and Stability

Evaluation of compaction behaviour helps ensure uniform density and minimizes risks of settlement and surface distress.

Supports Compliance With Road Specifications

Mechanical testing verifies conformity with MoRTH specifications, IS standards, and project requirements, enabling approval for road and infrastructure works.
