Underclay development beneath asphalt roads in Kansas
Loessial subgrade materials in contact with asphalt road surfaces in Kansas are undergoing changes in structure, color, and amount of less than 2-μ clay; structure is changing from massive or single grain to weak subangular blocky; amount of less than 2-μ clay is increasing; it is shown that changes are caused by micro-organisms utilizing asphalt as energy source; reducing conditions are set up at soil-asphalt interface by actions of micro-organisms where supply of air and oxygen is limited.
