What are material cost of wbm road construction?

The material costs of Water Bound Macadam (WBM) road construction primarily include aggregate (coarse and fine), water, and sometimes additives for stabilization. The coarse aggregate, typically crushed stone or gravel, is the main component, and its quality and size can significantly impact costs. Additional expenses may arise from transport, labor, and equipment rental, as well as the cost of binding materials like lime or cement if used. Overall, budgeting for these materials is crucial for successful WBM road projects.
