Montana tests show soil bacteria attack asphalt surfacing
Five years of tests by Montana Highway Department show that soil bacteria attack oils and soft resins in asphalt surfacing of highways, thereby hardening asphalt and making it brittle; studies concerned roads with double-shot penetration type or asphalt stabilized bases having extremely thin films on aggregate or clay; treating asphalt with pentachlorolphenol is simple and costs 30¢ per ton for treated mix.
