soil stabilization
Soil Stabilization addresses the root cause of most roadway deterioration -- weak subgrade structure. Stabilization by Hall Brothers Recycling and Reclamation is a cost-effective method for strengthening these subgrades. By strengthening the subgrade, overlay requirements can be reduced and service life can be extended.
Pavement performance and longevity are closely tied to the proper application of stabilizing additives that increase the compressive strength and stability of the base. While chemical additives are the right choice for many stabilization projects, we also offer mechanical stabilization and densification as well as asphalt treatments for granular bases. With this full set of options, we can select the optimum stabilization method for every set of conditions.
Preparation of existing roads for chemical treatment begins with removal of the surface material to expose the base. The equipment we use gets the job done fast and accurately. Our trimmers feature automatic controls to maintain grade and elevation. To assure precise additive application, we have designed and manufactured our own spreaders and equipped them with highly accurate metering systems and speed controls.
Spreading accuracy, thorough mixing, and attention to proper curing procedures enables us to consistently produce a strong, stable base -- whether we are applying portland cement, hydrated lime slurry, fly ash, calcium chloride, or various forms of asphalt cement.
1.Lime stabilization is the best defense against a road's worst natural hazard expansive clay soil. Effectiveness and ease of handling make hydrated lime slurry our first choice in clay soil stabilization. Hall Brothers Recycling and Reclamation has portable slaking tanks that allow production of lime slurry at the project site. We can produce over 32 tons of hydrated lime in under two hours.
2.Controlled and accurate application of additives is essential to getting a strong base and a long-lasting pavement. Our spreader trucks apply lime slurry at a predetermined rate on the scarified soil.
3.Our reclaiming machines mix the lime slurry into the soil to the depth and width specified. Mixing is critical. To optimize the chemical reaction between the slurry and the soil, it is necessary to thoroughly pulverize and mix the soil for intimate lime/soil contact. The slurry is uniformly dispersed throughout the soil during the mixing process, creating a homogeneous blend of lime, soil and water.
4.We use vane-type spreaders, also of our own design, to apply dry chemicals, like the dry cement additive being dispersed here. The application system allows tight control of spreading rates.
5.Our powerful reclaiming machines cut and mix an 8-foot swath. They can also add water to maintain prescribed moisture levels as they combine additives with the soil. Their exceptional productive capacity makes our stabilization work efficient and affordable.
