Long Term Pavement Performance Project Laboratory Materials Testing and Handling Guide

Protocol H05L
Standard Methods of Testing Emulsified Asphalts (SC01)

This LTPP protocol covers the tests performed on an emulsified asphalt. These tests are intended to be used on the emulsions used in the slurry and chip seals as part of the SPS-3 studies. The tests are to be run in accordance with AASHTO T59-89I, Standard Methods of Test for Testing Emulsified Asphalts, except Procedure B of Residue by Evaporation will be used to determine the quantity of residual asphalt and to recover the base asphalt for further testing. The following tests are not required: Identification of Residue by Evaporation, Oil Distillate by micro-Distillation, Settlement, Coating, Freezing, and Coating Ability and Water Resistance. Testing will begin within five days of the sample date.

The results will be recorded on LTPP Test Sheets H04A, H04B, H04C, and H05. The following table was prepared to define the specific tests to be applied to the samples of materials sent to the laboratory. Only those tests identified with an "X" are required. Separate sets of columns show the tests for the rapid setting emulsions used with the chip seals (Sample Material Code AECS) and for the slow setting emulsions used with the slurry seals (Sample Material Code AESL). Each of these has two columns identified as SO01 and Other. All of the tests shown under the column SO01 will be completed on the respective emulsion when the sample location code is SO01, SO02, etc. In addition, every fourth sample with other location codes will receive the testing shown under the respective column identified as SO01. The remaining samples will receive only the tests shown under the respective columns identified as Other.
