The TXI Hydrated Lime 50 lb. is useful to substantially increase the stability, impermeability and loadbearing capacity of subgrade. The lime is able to reduce plasticity and moistureholding capacity. The lime is also designed to improve stability and raise the pH level in soil. Plasticity reduction; Reduction in moistureholding capacity ...
Generally both lime and gypsum are sourced from set locations where either limestone is mined or FDG gypsum accumulates at an industrial plant scrubber. The cost of the material is one part of the charge but trucking can be a significant portion of the total cost per ton of material. Thus a standard cost is difficult to document but some ...
