A brochure proposing the use of Contained Rock Asphalt Mat (CRAM) provided a comparison of stress distributions throughout a CRAM structure (Figure 1) as compared to a conventional pavement (Figure 2). Experience has indicated that stress distributions do not always present the most sensitive or appropriate analysis of a pavement structure. Distributions of strains, and more particularly work , are better indicators of load distributions throughout a pavement structure and subsequent performance
