Guide — Road & Pavement Quantity
The road and pavement calculator below follows standard Indian construction practice and the relevant IS-code conventions. Enter the site dimensions exactly as measured, press Calculate Now, then refine the quantities line by line in the live sheet before you export.
Flexible pavement quantities follow the MORTH layer stack: granular sub-base, wet mix macadam, dense bituminous macadam and a bituminous concrete wearing course, each specified as a compacted thickness.
Bituminous layers are procured by weight, not volume. Compacted DBM and BC both weigh close to 2.4 t/m³, and binder content runs about 4.5% for DBM and 5.5% for BC by mix weight.
Add tack coat at 0.20–0.30 kg/m² between bituminous layers and prime coat at 0.6–1.0 kg/m² over the granular base. These small items are frequently missed and can be several lakh rupees on a kilometre of road.
Treat every output as an indicative pre-tender estimate. Site conditions, wastage allowances, specification changes and local market rates all move the final figure, so validate against your drawings and approved rate analysis before procurement.

About the Road & Pavement Quantity
This tool is built for site engineers, quantity surveyors, contractors and property investors who need dependable numbers fast. Every input is reactive — changing a single field instantly recomputes the full output set, so you can run sensitivity checks on dimensions, grades and rates before committing to an estimate.
Keep unit consistency in mind: metric inputs (metres, square metres, cubic metres) produce metric outputs, with imperial and Indian trade units shown alongside where they are commonly used on site.
