Summary:
The modification of bituminous materials with various kinds of rubber for use in seal coat construction has been used in
South Dakota as long ago as the mid 1950’s.  The use of ground rubber from discarded tires in relatively large
percentages is an innovation, which had not been tried preciously in the state.  The purpose of the study discussed in
this report is to demonstrate the construction procedures involved and to evaluate the performance of the resulting chip
seal.
