Aggregates are used in a variety of ways in highway construction, as shouldering material, bases, and of course, as an ingredient in the production of HMA and PCC. Both HMA and PCC are used for surfaces and patching on highways. During the design process many factors are considered when deciding on which surface would be the best choice since each has its own unique advantages. They both
