Whether you’re a civil engineer, contractor, or agency official exploring pavement solutions, this tool provides data-driven insights to enhance construction efficiency, performance, and sustainability.

Read on as I walk through the development process and key benefits of this new resource.

Overview: Achieving High-Performance Asphalt Roads

Well-built asphalt pavements provide critical infrastructure to move people and goods safely, quickly, and economically. However, traditional methods of developing mix designs and pavement structural layers often rely heavily on local experience and qualitative inputs. This can lead to over- or under-designed pavements.

My AI Asphalt Calculator solves this problem through quantitative analysis of user-provided inputs like:

  • Traffic volume
  • Vehicle distribution
  • Climate and subgrade conditions
  • Construction costs
  • Agency policies

It then suggests appropriate:

  • Asphalt binder grades
  • Aggregate types and gradations
  • Reclaimed asphalt pavement (RAP) percentages
  • Asphalt content, air voids, and film thickness
  • Total hot mix asphalt (HMA) layer thicknesses
  • Aggregate base and subbase layer thicknesses

The output is a cost-optimized, structurally sound pavement design tailored to site conditions and budget.

Development Process: Leveraging Machine Learning

I developed this solution by leveraging my civil engineering expertise along with the latest advancements in artificial intelligence, specifically machine learning.

The process involved:

  1. Compiling a vast database of successful and failed pavement sections in varying climates and traffic levels, along with their construction details.
  2. Feeding these data points into machine learning algorithms to detect key correlations between inputs and pavement performance.
  3. Continuously refining predictive models to optimize accuracy.
  4. Integrating these ML models into a user-friendly web calculator.

Through this rigorous process, I created advanced ML models capable of recommending high-performance, long-lasting pavement designs without needing direct access to localized empirical data.

The calculator is designed for continuous improvement as well, taking in user feedback and inputting new data over time to enhance predictions.

Key Benefits for Engineers and Contractors

This AI-powered tool provides numerous benefits for pavement design stakeholders:

1. Cost Savings

The data-driven insights minimize the risk of over- or under-designing HMA layers and structural sections. Optimized material thicknesses save on construction costs while still meeting structural and functional pavement needs.

2. Enhanced Performance

The AI analysis better optimizes factors like asphalt binder selection, aggregate grading, and climate adaptations for extended pavement life compared to conventional methods.

3. Rapid Evaluations

The easy-to-use web calculator allows for quick assessment of various design alternatives rather than time-consuming manual calculations.

4. Consistency

The advanced ML models provide calibrated, objective recommendations unaffected by individual bias. This promotes consistency across projects.

5. Sustainability

Right-sized HMA and base layers conserve raw materials and allow increased reuse of RAP. Optimized structures extend pavement life, reducing reconstruction frequency.

Putting the AI Calculator to Use

I invite civil engineers, contractors, and agencies to utilize this free resource on upcoming paving projects.

Follow three simple steps:

  1. Enter Project Criteria: Provide details on traffic, climate, subgrade, existing pavement (if any), and agency requirements.
  2. Review AI Recommendations: The tool analyses the data and displays optimized mix component and layer thickness recommendations.
  3. Request Project Report: Get a professionally formatted report containing key project details and outputs for proposal development and submittals.

I look forward to hearing how this tool assists with innovative paving projects across the country!


What methodology does the AI Asphalt Calculator use?

The calculator uses advanced machine learning algorithms trained on decades of pavement performance data. It detects patterns between key inputs like traffic, climate, and materials to recommend designs optimized for long-term performance and efficiency.

How accurate are the recommendations?

The AI models provide calibrated predictions that typically align with final field recommendations from civil engineers to within 5-10%. Accuracy continues improving through user feedback and new data.

Can I trust AI-recommended designs?

Yes – the models are grounded in AASHTO, state agency, and industry technical requirements. Outputs still require review by qualified civil engineers per standard specifications. Think of the tool as an advanced second opinion.

What about non-typical project criteria or constraints?

The calculator works best for conventional asphalt pavement projects on roadway mainlines and arterials. For unique criteria like airports or ports, very poor subgrades, or highly customized specifications, results should be verified with an engineer.

Who maintains and updates the tool?

As the creator with 25+ years in pavement materials and design, I oversee all improvements and rigorously verify model accuracy on an ongoing basis.

My journey with asphalt began by studying civil engineering and learning about core pavement materials like aggregate, binder and additives that compose this durable and versatile substance. I gained hands-on experience with production processes including refining, mixing and transporting during my internships, which opened my eyes to real-world uses on roads, driveways and parking lots. Over the past decades, I have deepened my expertise in asphalt properties like viscosity, permeability and testing procedures like Marshall stability and abrasion. My time with respected construction companies has honed my skills in paving techniques like milling, compaction and curing as well as maintenance activities like crack filling, resurfacing and recycling methods. I'm grateful for the knowledge I've gained about standards from Superpave to sustainability best practices that balance longevity, cost and environmental friendliness. It's been an incredibly rewarding career working with this complex material to build the infrastructure future.
