Grading I/Grading II (WBM) Rate Analysis Calculator

This calculator helps compute rate differences for Water Bound Macadam (WBM) Grading I and II based on PWD guidelines.

Select Grading: Grading II (63-45 mm, 75 mm thickness) Grading I (90-45 mm, 100 mm thickness) Basic Rate (₹): Cess Deduction (%): Tribal Addition (%): Coarse Metal Consumption (m³ per m³ compacted): Coarse Metal Unit Rate (₹ per m³): Screenings/Murum Consumption (m³ per m³ compacted): Screenings/Murum Unit Rate (₹ per m³):

Item Descriptions

Grading I: Providing, laying, spreading and compacting stone aggregates of specific sizes to water bound macadam specification including spreading in uniform thickness, hand packing to proper grade and camber, applying and brooming requisite type of screening/binding materials to fill up the interstices of coarse aggregate, watering and compacting with vibratory roller to the required density. By Mechanical Means - Grading I (Using Screening Type A (13.2 mm) Aggregate)

Grading II: Providing, laying, spreading and compacting stone aggregates of specific sizes to water bound macadam specification including spreading in uniform thickness, hand packing to proper grade and camber, applying and brooming requisite type of screening/binding materials to fill up the interstices of coarse aggregate, watering and compacting with vibratory roller to the required density. By Mechanical Means - Grading II (Using Screening Type B (11.2 mm) Aggregate)

Any corrections or suggestions are welcome!

Note: Input values in editable fields only. Consumption values are approximate loose quantities per m³ compacted volume (adjust based on site trials as per MoRTH Clause 404).
