ABSTRACT:
A method of reconstructing a bituminous-surfaced pavement is provided. This method includes evaluating the pavement to determine if it is an appropriate candidate for full-depth reclamation; mixing an emulsion with reclaimed asphalt pavement particles from the pavement to form an asphalt emulsion mix; and testing the asphalt emulsion mix for performance using a cohesion test, a moisture susceptibility test, and a modulus test. In many instances, dirt and/or aggregate from the base layer of the pavement are also included in the asphalt emulsion mix. The invention also includes designing a full-depth reclamation (FDR) layer based on this test data. Once the layer is designed, the bituminous surface of the pavement is pulverized, an emulsion is mixed with the pulverized reclaimed asphalt pavement particles from the bituminous surface and possibly dirt and/or aggregate from beneath the bituminous surface of the pavement, and this mixture is applied to the pavement.
