• Abstract:
  Material characterization is a critical component of modern day pavement analysis, design, construction, quality ; control/quality assurance, management, and rehabilitation. At each stage during the life of a project, the influence of ; several fundamental engineering material parameters on the long-term performance of the pavement can be predicted ; using advanced tools like the American Association of State Highway and Transportation Officials Mechanistic- ; Empirical Pavement Design Guide (MEPDG). Consequently, there is a need for more information about material ; properties, which are addressed only to a limited extent with currently available resources for performing laboratory ; and field testing. Reliable correlations between material parameters and index properties offer a cost-effective ; alternative and are equivalent to the level 2 MEPDG inputs. The Long-Term Pavement Performance (LTPP) database ; provides data suitable for developing predictive models for Portland cement concrete (PCC) materials, stabilized ; materials, and unbound materials, as well as other design-related inputs for the MEPDG. This user’s guide provides a ; summary of the models developed, describes their applications for specific project conditions, and lists their ; limitations. The following models are included: ; • PCC materials: Compressive strength, flexural strength, elastic modulus, tensile strength, and coefficient of ; thermal expansion. ; • Stabilized materials: Elastic modulus of lean concrete base. ; • Unbound materials: Resilient modulus of fine-grained and coarse-grained materials. ; • Rigid pavement design features: Pavement curl/wrap effective temperature difference for jointed plain ; concrete pavement and continuously reinforced concrete pavement designs.
