Stabilization

A Definition of Stabilization:

"Stabilization is the permanent physical and chemical alteration of soils and aggregates to enhance their engineering properties thus improving the load bearing capacity of a sub-grade or sub-base to support pavements and foundations."

-Asphalt Recycling & Reclaiming Association

Soil Stabilization

The Benefits of Soil Stabilization:

A PRO-ACTIVE SOLUTION:

  • Addresses underperforming sub-grades prior to construction rather than reacting to the problem afterwards with costly repairs to pavements, building slabs, and foundations.
  • Improved resistance to frost penetration in sub-grade.

IMPROVED PROJECT SCHEDULE:

  • Allows for immediate access to sites that otherwise might not be accessible due to poor sub-grade conditions.

CONSERVES ENERGY:

  • In-place process means no hauling away or importing of new engineered material.

CONSERVES MATERIAL:

  • Recycling existing materials saves natural resources and energy.

COST EFFECTIVE:

  • Existing materials stay on site eliminating unnecessary trucking and disposal costs.
  • Increased load bearing capacity means reduced need for over designed footings, slabs and pavement sections.

ENVIRONMENTALLY FRIENDLY:

  • Eliminates material disposal concerns.
  • Pollution resulting from material hauling is practically eliminated.
Increased Load Carrying Capacity

The Soil Stabilization Process:

STEP 1: TESTING

Lab tests analyze the aggregate and soil selected for the project and a custom combination of depth, additive and water is designed to meet the load-bearing capacity required for the use of the site.

Step 1: Testing
STEP 2: Spread/Mixing

STEP 2: SPREAD/MIXING

In most cases, the soil and aggregates are pre-existing on site and the proper quantity of additive is applied onto the surface with a calibrated spreader. Then, in one step, a reclaimer/stabilizer blends the soil/aggregates, additive and the optimum amount of water to the required depth.

STEP 3: COMPACTION/CURING

The blended mixture is then compacted using vibratory rollers. Once hardened, the modified material does not compact further under traffic and is resistant to settling. This results in a ready-to-use, durable, subgrade or base.

Step 3: Compaction/Curing
Step 4: Construction

STEP 4: CONSTRUCTION

The entire stabilization process can be completed over large areas in one day. From there, further construction operations can then continue on top of the improved surface.
