Evaluation and Analysis of LTPP Pavement Layer Thickness Data

Publication Number: FHWA-RD-03-041

Evaluation and Analysis of LTPP Pavement Layer Thickness Data

Table 67 presents correlated groupings of "similar" materials used to correlate material codes from inventory and testing tables. The first two columns provide material codes and LTPP material descriptions used in the TST* tables. The second and third columns provided material codes and LTPP material descriptions used in the INV*, RHB*, and SPS* tables. The last column shows "similar" material descriptions developed in this study to link testing and inventory material codes.
