Hot-Recycled Asphalt Mixtures with Reclaimed Asphalt Pavement (RAP) at 10%, 20%, and 30%

Laboratory test results for hot-recycled asphalt mixtures containing different percentages of Reclaimed Asphalt Pavement (RAP). The data includes mechanical properties, stiffness, and adhesion tests for mixtures with 10%, 20%, and 30% RAP compared to a virgin reference mix. This study by Roberta Centofante was published as an Open Access paper on paperswithcode.

Use Cases

• Predicting binder savings based on RAP percentage, as the study observed reductions between 12.9% and 35.7%.
• Modeling the effect of RAP content on mixture stiffness using resilient modulus and dynamic modulus test results.
• Assessing resistance to permanent deformation based on Flow Number test results mentioned in the description.
• Evaluating moisture damage susceptibility using results from the Modified Lottman test described in the abstract.

Strengths

• The description provides specific quantitative results, such as binder savings of 12.9% to 35.7% for 10% and 30% RAP mixtures.
• Multiple standardized mechanical tests are documented, including resilient modulus, dynamic modulus, indirect tensile strength, and Cantabro abrasion tests.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
