Abstract
Hydrologic Consultants, Inc. was contracted to undertake the closure of a former pesticide facility. While pesticide compounds were present on the site, they were located primarily in the top two feet of soil. Five remedial action alternatives for the site were reviewed; the remedial action selected was to cap the site. Because of the expense of obtaining clay in sufficient quantities, a less costly alternative to clay was adopted: a high-bitumen-content hydraulic asphalt concrete (HAC) pavement. For preliminary design purposes, a performance assessment was conducted utilizing the Hydraulic Evaluation of Landfill Performance (HELP) model to compare the relative performance of clay and asphalt capping material. The results of model simulations indicated that the asphalt pavement design with a permeability value of 10-8
