Abstract:

Reclaimed stabilized base (RSB) is a common technique utilized to rehabilitate roadways. RSB involves reclaiming the base material and adding a stabilizing agent to increase the strength and durability of the base/subbase structure. This technique involves pulverizing some of the existing pavement along with a portion of the underlying base material, adding aggregate material as necessary to accommodate grade changes, adding a stabilizing agent, and thoroughly mixing the components in place to create a homogeneous mixture. Utilizing RSB can lead to increased service life of the pavement and consequently significant maintenance cost savings compared to pavement overlay without improving the base conditions. However, determining the appropriate stabilizing agent and design for various subbase materials remains a challenge, particularly for cold winter climate locations.
