Modified Rubblization

This set of photos presents modified rubblization. When rubblizing over subgrade/base providing only fair to poor support it is often counterproductive to try to achieve small particle sizes because the resulting rubblized concrete layer would not provide adequate structural support for the overlay. Experience has shown that a modified rubblization pattern that employs less fracture energy in order to produce a somewhat stiffer rubblized concrete layer (larger particle sizes) will maintain enough of the concrete layer’s strength to support construction operations and the new asphalt overlay while still eliminating reflective cracking.
