Estimation of Key PCC, Base, Subbase, and Pavement Engineering Properties from Routine Tests and Physical Characteristics

The U.S. Federal Highway Administration (FHWA) has released a report that explores critical data needs for the design, construction, and pavement management operations under the Long-Term Pavement Performance (LTPP) Data Analysis Technical Support contract.

The report also highlights efforts to develop predictive models to estimate Portland cement concrete and unbound material properties using LTPP data.

FHWA has released a user’s guide in conjunction with the report.
