Subgrade Preparation Calculator
Calculate material requirements and costs for subgrade preparation in construction projects. Estimate aggregate, soil stabilization, and compaction needs for roads, foundations, and pavements.
Step 1: Project Area & Depth
Understanding Subgrade Preparation
Subgrade preparation involves stabilizing the soil to support pavement or foundation loads. Proper compaction and material selection are critical for long-term structural integrity and load-bearing capacity.
Step 2: Material & Cost Details
About Compaction & Materials
Different soil types require specific preparation techniques. Clay soils often need lime stabilization, while sandy soils require proper compaction. Material costs vary based on local availability and transportation distance.

Cost Breakdown Analysis
Subgrade Cost Formula
Cost = (Area × Depth × Material Density) × (Material Cost × (1 + Wastage%))
The total cost is calculated based on the volume of material needed, adjusted for compaction requirements and material wastage. Actual costs may vary based on site accessibility, equipment requirements, and local labor rates.
