Frequently Asked Questions
What is GSB?
GSB stands for Granular Sub Base. It is a layer of crushed stone aggregates laid directly on the subgrade soil to prevent capillary water rise and distribute load.
How many cubic feet is one ton of asphalt?
Asphalt is dense (approx 2300 kg/m3). One Metric Ton of asphalt is roughly 15-16 cubic feet depending on compaction.
