Pavement structural evaluation
Determine the bearing capacity of your road infrastructure with structural pavement evaluation.
Pavement structural evaluation uses non-destructive testing (NDT) to determine the bearing capacity and overall condition of the road infrastructure
Among the equipment operated by Strinso are Falling Weight Deflectometers (FWD), Heavy Weight Deflectometers (HWD), and Light Weight Deflectometers (LWD) to precisely measure load-induced pavement deflections.
Our engineers analyze deflection data to determine the structural characteristics of the pavements. Using this information, additional analyses can be performed to estimate the pavement’s service life and identify appropriate rehabilitation alternatives that optimize available resources.
What is pavement structural evaluation?
Pavement structural evaluation is a comprehensive service that provides an in-depth, detailed analysis of your infrastructure's structural condition, covering aspects such as:
Destructive testing
Conducting invasive testing to determine the pavement’s compressive, flexural, and impact strength.
Shear testing: Determines the compressive and shear strength of the pavement material.
Penetration testing: Evaluates the compaction and density of the pavement material.
Data analysis
Evaluates the pavement’s structural capacity for traffic through inspections and testing, utilizing software and statistical techniques to achieve precise results.
Non-destructive testing (NDT)
Employment of advanced techniques such as Falling Weight Deflectometers (FWD), Ground Penetrating Radar (GPR), and ultrasound to evaluate the structural integrity of the pavement without damaging it. These techniques include:
- Falling Weight Deflectometers (FWD): Measure pavement deflection under dynamic loads to estimate its bearing capacity.
- Ground Penetrating Radar (GPR): Uses electromagnetic waves to explore the subsurface and detect structural anomalies, such as voids, settlements, changes in material density, or the presence of groundwater.
Preparation of comprehensive reports
The preparation of detailed reports that present the evaluation results in a clear and concise manner, including:
- Description of the methodology used.
- Findings from each stage of the assessment.
- Evaluation of the pavement’s structural condition across different sections.
- Identification of faults, deterioration, and potential risks.
- Recommendations for pavement maintenance, rehabilitation, or reconstruction.
- Findings from each stage of the assessment.
- Evaluation of the pavement’s structural condition across different sections.
- Identification of faults, distresses, and potential risks.
- Recommendations for pavement maintenance, rehabilitation, or reconstruction.
