Sulfate Leaching from Sulphur Binding Agents in Experimental Asphalt Pavement, Angelina County, Texas

<p>Sulfate leaching from sulphur-binding agents used in asphalt pavement was significantly higher (p>.05) from four layers of a mixture of a single aggregate base material of hot sand, when compared to all other treatments. Analysis of the data showed that the other treatments had no overall effect on the soil sulfates. Four layers of a single aggregate of hot sand increased the quantity of sulfates in the soil by 107%. I recommend the use of sulphur-asphalt binder with the type "D" base material throughout construction or when two layers of the type "D" base material are placed on top of two layers of hot sand. I also recommend caution be used when this binder is used with just the hot sand base material, unless a calcareous material is mixed with the asphalt.</p>
