• Description:
  The purpose of this report is to identify differences in Colorado's aggregates and asphalt cements as measured and compared to some of the European tests and specifications. Performance-related tests for asphalt cements developed by SHRP will be the ultimate method to identify performance and should be well received in Europe. Based upon the standard empirical tests on asphalt cements from four refineries commonly used in Colorado, the asphalt cements are comparable to those used in France. The 17 most frequently used aggregate sources in Colorado were tested for this study. The angularity of fine aggregates is measured with the NAA test procedure. The quality of the P200 is measured with respect to angularity, durability, and stiffening. Angularity of P200 is measured with the stiffening power, durability with the methylene blue and sand equivalent tests, and stiffening with the power of absorption, stiffening power (ring and ball softening point) and Rigden voids index test. The results from these tests are interrelated. -Gradations commonly used by the French and Germans are compared to the CDOT master range.
