FULL DEPTH RECLAMATION (FDR)

RECYCLE ASPHALT PAVEMENT ECONOMICALLY WITH LIME KILN DUST

Jones-Warner Consultants, Inc. has more FDR experience in Ohio than most other engineering firms.  FDR has proven to be a great option for many of our clients as a process that is:
  • effective (strong, durable, and potentially self-healing)
  • cost-saving (typical savings of 40%)
  • environmentally-friendly (fewer materials needed, no need to haul away existing pavement)
  • fast (can be implemented more quickly than total reconstruction and can handle same day local traffic) 

For these reasons, we believe it is an option worth considering for all of our clients when evaluating the need for reconstruction of existing roads.  With our knowledge and experience we are prepared to handle unique needs and situations and are very familiar with all the options available for the FDR process.
Full Depth Reclamation (FDR) is a maintenance process by which the full flexible pavement section consisting of asphalt, base, sub-base, and a pre- determined portion of the underlying soil subgrade are uniformly pulverized and blended with Lime Kiln Dust (LKD), resulting in a stabilized base course.

FDR using LKD offers numerous benefits:
  • Ideal where base has structurally failed,and / or granular base is no more than 6 inches
  • Lower cost (typically 40% cost savings over reconstruction)
  • Achieve greater strength and durability than with alternative products
  • Achieve optimum moisture and strength of sub-base and subgrade even under very wet conditions or high clay content
  • As a highly effective and economical, cementitious reagent, LKD is often used for new construction subgrade beneath roadways, airports, and parking lots, by which the component of lime is known to substantially increase subgrade soil stability, load bearing capacity, and long-term durability.
  • Lime is typically specified as the agent of choice to enhance the bonding of asphaltic cement to an aggregate.
  • The FDR process of recycling the combined layers of asphalt pavement, the base, and the subgrade is similar to soil mixing, making it an easy and familiar process to most contractors.
