    History of Concrete Highways. The first concrete highway constructed in the United States was a 24-mile long, 9-foot wide, 5-inch thick strip of concrete pavement built near Pine Bluff, Arkansas, in 1913—five years after the introduction of the Model T Ford. By 1914, concrete had been used to pave 2,348 miles of roadway.

    Pavement condition should be considered before installing rumble strips in existing pavement. Although milled rumble strips do not typically cause issues when installed in pavement rated fair or better, in older pavements that show high degrees of deformation or cracking distress, the milling process can exacerbate existing issues.

  • Pavement Types - Pavement Interactive

    Each of these pavement types distributes load over the subgrade in a different fashion. Rigid pavement, because of PCC's high elastic modulus (stiffness), tends to distribute the load over a relatively wide area of subgrade (see Figure 1). The concrete slab itself supplies most of a rigid pavement .
