The ALFA Lightweight Deflectometer (LWD) is a portable, non-destructive field-testing system used to rapidly assess bearing capacity and compaction quality of subgrade, granular layers, and unbound pavement bases by measuring surface deflection under an impulse load and calculating dynamic deformation modulus (Evd).
The system is designed for fast on-site quality control and documentation, featuring tablet-based operation, high-capacity internal data storage, and modern communication options for streamlined reporting, data export, and project traceability.
Digital connectivity includes Bluetooth + Wi-Fi, USB-C, a thermal printer interface, GPS, and direct integration to ALFA Cloud for centralized storage, reporting, and fleet/project management workflows.
