Stevenson railway ballast is manufactured through a robust production process which ensures high consistency in compliance with the Track Specifcation T140.

Incoming aggregate which has been  crushed and screened, is then disaggregated into various size ranges into large blending bins. These aggregates are then selected in precise proportions by weight and blended through our leading edge computer controlled blending plant to produce the final product. Calibrated weigh scales provide confidence in these mix proportions. Stockpile control and testing is carried our prior to clearance for loadout to customers
