Fact Sheets

Asphalt Paving Handbook

The 2025 Asphalt Paving Handbook provides practical guidance and best practices for paving asphalt mixtures on roadway and airfield projects. It focuses on the factors that most affect pavement quality and long-term performance.

This Fact Sheet provides a two-page summary of need-to-know content in the handbook.

Validating Gyration Levels for Airport Asphalt Mix

This study evaluated the number of SGC gyrations needed to produce airfield asphalt mixtures with volumetric properties equivalent to those achieved using 50- and 75-blow Marshall compaction.

This Fact Sheet provides a two-page summary of findings, advantages, and implementation strategies from this study.

Balanced Mix Design: Rutting Performance Tests

Airfields require more than traditional volumetrics can predict. This study evaluated rutting performance tests that strengthen Balanced Mix Design and more accurately capture how asphalt mixtures perform under heavy aircraft loads, high tire pressures, and elevated temperatures.

Guidance for Selection of Proper Asphalt Binder Grade

Airfield pavements face heavy loads and strict specifications, making binder choice critical. This fact sheet summarizes research that simplifies binder selection and introduces a free online tool to help engineers save time, reduce errors, and improve pavement performance.

Preventing Slippage Failures at Airfield Pavements

High-speed exit taxiways can cause severe stresses on asphalt surfaces, leading to shoving, cracking, and foreign object damage. This fact sheet summarizes research on why slippage failures occur and provides guidance on material specifications, overlay thickness, and design practices to prevent them.
