As you have probably noticed, the project is currently underway with the liming process for the sub-grade of the new road build. We apologize for this portion of the inconvenience as it is necessary for the proper strength support of the construction at hand. Attached is the most recent scheduling of events for the street project.
Lime stabilization is used primarily to upgrade poor quality clay soils in order to provide adequate subgrade support- a prime requisite for good concrete slab performance. Lime's use is especially valuable when expansive clays are encountered. Expansive clays have been known to crack concrete slabs or to create rough joints as the slabs heaved and then settled during wet and dry cycles. Lime alleviates this problem first by reducing the soils' expansive properties and second by forming a moisture barrier which helps prevent water from reaching the underlying expansive subsoil. Lime stabilization is essentially a type of chemical stabilization process involving hydrated lime. The technique is applicable to heavy clay and silty clay soils, and to plastic aggregates such as pit-run gravel. The reaction between the lime and the clay is essentially two-fold: first, during mixing, the clay particles are brought together into one mass due to base exchange, forming coarser silt sizes. This reduces the plasticity and swells and increases the friability of the soil. There is also a pronounced drying action. After compaction, the lime reacts with the clay to form a type of cement which binds the soil particles firmly and greatly increases the strength and stability of the soil.
