RESISTANCE OF ROLLED ASPHALTS TO ATTACK BY PETROLEUM OILS

The research reported was carried out to (1) compare the resistance to petroleum oils of rolled asphalts made with bitumen of high permittivity and pitch-bitumen, and (2) to compare the kerosene-resistance of these rolled asphalts with that of dense tar surfacing. Marshall moulds of the different materials were prepared and immersed in petroleum oils for various times and damage was assessed by measuring Marshall stability and flow. It was concluded that the petroleum-oil resistance of rolled asphalt made with pitch-bitumen is slightly better than that of high-permittivity-bitumen asphalt. The petroleum-oil resistance, and especially kerosene resistance, of both types of asphalt is markedly inferior to that of dense tar surfacing which remains the recommended conventional bituminous material for use in areas where severe petroleum-oil contamination is to be expected.
