Materials data include the data necessary to characterize the various layers of each test section. The following categories of materials data are collected:
The material testing data represent the condition of the material at the time of sampling and testing. Therefore, these results may incorporate the effects of the season and the pavement age at time of sampling and testing.
The primary objective of this testing program is to provide a comprehensive evaluation of the pavement layer structure and layer thicknesses of the pavement materials used in each section or project. The work is accomplished by core drilling, augering, test pit opening, sampling, and nuclear density testing along with the subsequent performance of a suite of laboratory material characterization tests. To facilitate the collection of these data, standard laboratory testing protocols and data entry sheets have been developed for recording all data collected in the field and in the laboratory.
The DCG provides some general information regarding the collection of materials data with respect to the LTPP program. Other documents, referenced below, provide more detailed information about the appropriate methodologies to be used in obtaining and reporting these data.

A different approach has been taken in the materials sampling for the GPS experiments and the SPS experiments. In addition, the sampling approach for each SPS experiment is different. Therefore, a separate materials sampling guide was prepared for the GPS test sections, and there is a specific guide for each of the SPS experiments. For each SPS project, a unique sampling and testing plan was prepared before construction of the project. The SPS experiment-specific guidelines provide the approach to be used in preparing the project-specific plans.

This guide provides detailed instructions for performing and documenting laboratory testing and information on laboratory processing of samples. It also contains the individual protocols used in laboratory testing along with the methods for disposing of the samples once testing has been completed. The revisions listed below generally include the submittal of a new or revised protocol for a particular test via a materials directive.
