SPR-4716: Lessening Density Requirement and Adjusting Density Pay Factors for Asphalt Pavements in Poor Sublayer Conditions

The main objectives of the study are (1) to identify the correlation between the density of the new surface layer and the condition of existing sublayers of HMA pavements and (2) to make recommendations for adjusting the density pay factor of the INDOT standard specification based on the identified correlation. The study will support the INDOT to make a data-driven density specification change.
