Engineers are guided to consider both initial construction costs and future maintenance expenses when analyzing alternatives.

The guide provides methodologies for conducting lifecycle cost analyses (LCCA), which account for the entire service life of the pavement. This includes estimating future expenditures for repairs, resurfacing, and rehabilitation. By incorporating these factors, the economic evaluation helps identify the most economical solution that balances upfront investments with long-term savings.

Additionally, the guide encourages the use of discount rates to evaluate costs over time, ensuring that future expenses are appropriately weighted against present-day expenditures. This comprehensive approach allows decision-makers to prioritize designs that offer the best value for public investment. The economic evaluation process is integral to achieving sustainable and fiscally responsible pavement design solutions.

Comparison of the 1993 AASHTO Guide and the Mechanistic-Empirical Pavement Design Guide (MEPDG)

The 1993 AASHTO Guide and the Mechanistic-Empirical Pavement Design Guide (MEPDG) are two influential documents in pavement design, each offering distinct approaches. The 1993 AASHTO Guide is primarily empirical, relying on data from the AASHO Road Test, while the MEPDG integrates both mechanistic and empirical methods for improved accuracy.

One key difference is the design methodology. The 1993 AASHTO Guide uses simplified equations based on historical data, making it straightforward but less flexible for modern materials. In contrast, the MEPDG employs advanced mechanistic models to analyze stress-strain responses and predict pavement performance under various loads and environmental conditions.

Another significant distinction lies in their handling of material characterization. The MEPDG requires detailed input parameters for each pavement layer, allowing for precise design customization. The 1993 AASHTO Guide, while effective for its time, relies on broader assumptions that may not account for current advancements in materials science.

Overall, the MEPDG represents a more sophisticated evolution in pavement design, offering enhanced accuracy and adaptability compared to the 1993 AASHTO Guide. However, the latter remains a foundational reference, particularly for its historical context and simplicity.
