Pavement Design Services
Atlas Engineering and Technology Group offers extensive pavement design expertise to projects throughout Sydney. Our skilled geotechnical engineering team implements proven methodologies and strategies to ensure durable, budget-conscious pavement solutions across various applications.
Understanding Pavement Fundamentals
Pavements serve two critical functions:
- Structural Performance: The pavement must be sufficiently thick and of good material quality to withstand heavy vehicle loads and distribute them to the underlying soil.
- Functional Performance - The pavement must provide good riding quality, adequate drainage, skid resistance, and safety features for road users.
Types of Pavements We Design
Flexible Pavements
Flexible pavements include unbound granular materials, stabilized materials, and/or asphalt layers. They distribute loads through inter-particle friction and can be constructed in stages. Common types include:
- Unbound granular pavements with thin bituminous seals
- Bound (stabilized) pavements
- Full-depth asphalt pavements
Rigid Pavements
Rigid pavements consist of high-strength concrete bases with various subbase materials. They distribute loads through slab action and include:
- Joined unreinforced concrete
- Jointed reinforced concrete
- Continuously reinforced concrete
- Steel fibre reinforced concrete
Our Pavement Design Process
Our comprehensive approach includes:
- Site Investigation - Thorough assessment of subgrade conditions through field testing and sampling
- Traffic Analysis - Determination of design traffic loads and volumes
- Material Selection - Identification of appropriate materials based on availability and performance requirements
- Structural Design - Calculation of layer thicknesses using industry-standard software (CIRCLY and ELMOD)
- Drainage Design - Integration of appropriate drainage solutions to protect pavement integrity
- Construction Specifications - Development of detailed construction guidelines
