Automatic Crack Detection
The Heavy Weight Deflectometer (FWD)
Purpose
The Heavy Weight Deflectometer (HWD) is a non-destructive testing (NDT) device that provides realistic
deflection basin parameters that can be used as an input into a mechanistic pavement model to quickly
and adequately determine the structural condition of the pavement.
Methods
A falling weight impacts a specially designed rubber spring system, producing a half-sine load
pulse lasting 25-40 ms, simulating a 50 kN wheel load. Each test point is completed within
approximately 40 seconds.
Deflection is recorded with absolute accuracy better than 2% + 1 micron, and relative accuracy
typically 1% + 1 micron. The load is applied and measured to within ±2% + 0.3 kN.
Outputs
Field deflection values collected at set intervals are analyzed with pavement layer thickness
and traffic loading data using multilayer elastic modeling. Results include:
- Resilient modulus (E-value) of pavement layers
- Estimated Subgrade CBR
- Remaining pavement life
- Required overlay thickness
Compliances with Standard
- • AASHTO Design of Pavement Structure
- • ASTM D4694 — Deflection Measurement
- • ASTM E1845 — Macrotexture
- • ASTM D4695 — HWD Test Method

Coring & Dynamic Cone Penetrometer (DCP)
Introduction
The DCP test is carried out normally on top of the unbound road base
layer immediately after coring to determine the thickness and
structural properties of the unbound layers. It can also be performed on
top of soil or subgrade to determine the CBR value.
Methodology
The TRRL DCP set consists of a 16mm diameter hardened steel rod with an 8 kg hammer
that drops from a height of 575mm. The rod is fitted with a 60-degree cone having
a 20mm diameter. During testing, the hammer is raised and released to strike the anvil,
causing the cone to penetrate the unbound pavement layer.
Penetration readings are recorded using a measuring scale fixed to the rod. For
harder surfaces, readings are typically taken after 10 hammer drops. As the cone
penetrates deeper into weaker layers such as sub-base and subgrade materials,
the number of blows is reduced progressively (5, 3, and 1 blows) according to
the material strength response.
Output
The penetration rate (mm/blow) is plotted against the number of blows to generate
a resistance curve. The slope of this curve indicates material strength, and changes
in slope represent transitions between pavement layers.
The depth where the slope changes identifies the boundary between layers, which
can be used to estimate layer thickness. If penetration does not occur after
30 consecutive blows, an electric drill is used to bypass the hard layer and
continue testing.
The California Bearing Ratio (CBR) of the subgrade is estimated using:
CBR = 269 / DCP
where DCP is the penetration rate in mm/blow.

INFRASTRUCTURE HEALTH
Specialized non-destructive testing (NDT), geotechnical investigation, and deformation monitoring for critical assets.
Introduction
Our team provides professional Structural, Building, and Slope Condition Assessments designed to meet diverse engineering and safety requirements.
These services act as a comprehensive “health check” for both structures and slopes, ensuring long-term stability and resilience.
Building Condition Assessment ensures that assets such as buildings and bridges are safe to occupy, with defects and deterioration identified early for timely intervention.
Slope Condition Assessment identifies weaknesses within slopes and embankments, evaluating landslide vulnerability and stability.
Using advanced solutions such as wireless monitoring systems, real-time sensors, and Augmented Reality (AR),
we deliver predictive data and proactive countermeasures to prevent slope failures.
Service Features
• Check the structural condition and adequacy of existing structures using various assessment techniques and engineering standards.
• Conduct visual and NDT-based inspections for signs of cracking, settlement, corrosion, or other structural distress.
• Perform Geotechnical Forensic & Failure Investigations to determine root causes of damage or instability.
• Carry out Landslide Hazard & Risk Mapping to assess vulnerable zones and support mitigation planning.
• Execute field testing, document reviews, and as-built reconstruction for engineering verification.
Advanced Capabilities
• Utilize state-of-the-art UAV and AI-driven solutions for 3D terrain mapping, deformation tracking, and site visualization.
• Implement digital inventory and geotechnical data management systems for accurate asset traceability.
• Deploy wireless instrumentation and real-time monitoring for slope and structural movement detection.
• Provide Geotechnical Audit and Supervision for construction, rehabilitation, and maintenance projects.
• Integrate predictive analytics and Geo-AI to forecast performance and optimize maintenance cycles.
Success Stories
Over the past few years, our projects have contributed to the modernization of transportation,
urban planning, and public safety systems across Malaysia. From municipal roads to airport
runways, we deliver accurate, data-driven pavement and infrastructure insights that help
decision-makers plan smarter and build better.
