• Abstract:
  We examined CDOT design procedures, blasting methods, blast calculations, and aesthetic considerations to specify best management practices for highway rock cut operations for the Colorado Department of Transportation (CDOT) that could be followed when a Contractor or Permittee is proposing to blast. Though aesthetics are highly subjective, we developed a method to assign quantitative values for aesthetics, called the Percent Aesthetic Enhancement (PAE). The PAE is constituted as a quantitative assessment that defines the level of effort required for the enhancement of aesthetic features in final road cuts. By following these practices, the CDOT Engineer-In-Charge can ensure that the Contractor accomplishes the work in a safe manner while preserving scenic, aesthetic, and environmental resources.
