Falling Weight Deflectometer

At PDCE Group, our commitment to delivering sustainable and high-performance infrastructure is backed by the use of state-of-the-art technologies. One such innovation is the Falling Weight Deflectometer (FWD) – a critical tool for evaluating pavement strength and structural integrity. As an ISO 9001:2015 & ISO/IEC 20000-1:2018 certified multi-disciplinary engineering consulting company, PDCE Group employs advanced FWD testing as part of our comprehensive pavement investigation and asset management services across India.

What is a Falling Weight Deflectometer?

The Falling Weight Deflectometer is a non-destructive testing (NDT) device used to assess the structural capacity of in-service pavements. It simulates the load of a passing wheel by dropping a known weight onto a loading plate placed on the pavement surface. Sensors then measure the resulting deflection of the pavement at various distances from the load point.
This data is used to calculate modulus of elasticity of pavement layers, detect weak zones, and determine overlay thickness or rehabilitation strategies. FWD testing is essential for pavement performance analysis, maintenance planning, and design validation.

Key Features of PDCE Group’s FWD Services:

Measurement of RL (Coefficient of Retro-reflected Luminance)
Assessment of signboard retro-reflective materials
Compliance checks with IRC, ASTM, and MoRTH standards
Condition audits for maintenance planning
Daytime and nightime visibility evaluations

Applications:

Pavement management system development
Structural capacity assessment for roads, highways, airports
Validation of pavement design assumptions
Performance-based maintenance planning
Support for Detailed Project Reports (DPRs)

FAQs

Falling Weight Deflectometer (FWD) — common questions

Why use FWD instead of Benkelman Beam?

FWD simulates real moving traffic more accurately, is faster and gives data for each layer, which leads to better overlay design.

Which code is followed?

FWD testing and analysis follow IRC:115 guidelines.

Is lane closure required?

Only short, moving work zones are needed; the test is quick at each point.

Do you provide Falling Weight Deflectometer (FWD) near me?

Yes. PDSS Lab serves clients across India through our regional offices; our engineers travel to site and samples are tested in our NABL-accredited laboratory.

How can I verify a PDSS Lab report?

Every report has a unique number and QR code. Scan it or enter the number at verify.pdsslab.com to confirm it is genuine.
