Our Services
Comprehensive Pavement Investigations
The success of any pavement design begins with a thorough investigation of site conditions. Our pavement investigations involve detailed site assessments to collect critical data on subgrade conditions, existing pavement structures, traffic loads, and environmental factors. These insights allow us to create informed, tailored designs that maximise the lifespan and functionality of your pavements.
Key Components of Our Investigation:
- Site Assessment: We conduct a detailed examination of soil, subgrade conditions, and existing pavement structures to assess their suitability for the proposed project.
- Traffic and Environmental Analysis: We evaluate traffic volumes, load-bearing requirements, and environmental conditions such as local climate to ensure your pavement is designed to withstand both short- and long-term stresses.
- Compliance with Standards: Our investigations are conducted in strict accordance with Austroads, TfNSW, and rail specifications, ensuring full regulatory compliance.
Expert Pavement Design Solutions
Once the investigation is complete, we use the gathered data to develop tailored pavement designs that meet the unique demands of your project. Our designs consider every factor that impacts pavement performance, from load-bearing capacity to material selection, drainage, and structural integrity. The result is a robust, durable pavement solution designed to handle both traffic loads and environmental stresses.
Design Considerations Include:
- Material Selection: We choose materials that best suit your project’s requirements, ensuring long-lasting performance and cost-effectiveness.
- Structural Design: Our engineers design pavement layers that can withstand the expected traffic and environmental conditions, providing strength and stability.
- Drainage Solutions: We incorporate effective drainage systems to prevent water accumulation and minimise long-term damage to the pavement.
- Regulatory Compliance: All our designs meet the stringent standards of Austroads, TfNSW, and rail specifications, ensuring your project is fully compliant.
Material Assessment
We perform comprehensive material assessments to ensure that the materials used in your pavement construction meet the required standards for strength and durability.
Material Assessments Include:
- Unconfined Compressive Strength
- Lime Demand
- Concrete Flexural Strength
Subgrade Assessment
Subgrade strength is a critical factor in determining the success of any pavement. We conduct in-depth subgrade assessments to ensure that the base of your pavement can support traffic loads and environmental factors.
Subgrade Assessments Include:
- California Bearing Ratio (CBR)
- Plate Load Testing
- Sieve Analysis
- Nuclear Density Gauge Testing
Design Recommendations
Our detailed design recommendations provide clear guidance on how to achieve the optimal pavement structure for your project. We focus on maximising longevity, durability, and cost-effectiveness.
Design Recommendations Include:
- Layer thicknesses for pavements
- Stabilisation by additives (e.g., lime, fly ash, cement)
Frequently Asked Questions
1. What is involved in a pavement investigation?
A pavement investigation includes assessing the existing pavement, subgrade conditions, and environmental factors like traffic loads and climate. It provides critical data for designing pavements that are safe and durable.
2. Why is traffic load analysis important in pavement design?
Traffic load analysis ensures that the pavement is designed to withstand the expected traffic volumes and weights, preventing premature wear and failure.
3. What materials are tested during pavement assessments?
We assess a variety of materials, including subgrade soil, concrete, and asphalt. These tests help ensure that the materials meet the necessary standards for strength and longevity.
4. Do you offer pavement rehabilitation services?
Yes, we provide pavement rehabilitation and maintenance services, including recommendations for resurfacing or repairs based on current pavement conditions.

Our dedication to quality, precision, and compliance ensures that your pavements are designed for maximum durability, safety, and cost-effectiveness.
Specialist Capability
Plate Load Test
Hunter Geotechnical Services’ Plate Load Test can quickly and easily determine the bearing capacity of soils and deflection of soils.
The test is performed by systematically applying 6-8 equal load steps to the static plate, and calculating the pressure settling lines and deflection modules of the first load (Ev1), and the second load (Ev2) – ultimately represented in NM/m2.
The test is performed in-situ, gives instant results, and has the added benefit of being non-destructive – with no drilling or sampling. Our Plate Load Tests are performed in accordance with DIN 18134:2012-04.
