Use of Reclaimed Asphalt Pavement in Conjunction with Ground Improvement: A Case History

Table 2

Summary of AASHTO [3] Design Inputs Used to Analyze Pavement Sections. Original design value for resilient modulus was inferred from project specifications. Design ESALs were back calculated from original design pavement section.

Design Parameter	Original Design Value	Remedial Design Value
Asphalt Wearing Course Layer Coefficient	0.42	0.42
Dense-Graded Asphalt Course Layer Coefficient	0.40	0.40
Aggregate Base Course Layer Coefficient	0.14	0.24
Subgrade Resilient Modulus	83 MPa	27 MPa
Target Design ESALs	176,000	176,000
