Long Term Pavement Performance Project Laboratory Materials Testing and Handling Guide

Protocol H19L
Determination of Asphalt Content from Slurry Seal Sample (SC12)

This LTPP protocol covers the determination of asphalt cement content from slurry seal samples taken in the field as a part of the SPS-3 studies. The extraction shall be performed in accordance with AASHTO T164-89I, Standard Method of Test for Quantitative Extraction of Bitumen from Bituminous Paving mixtures, except as designated below. Reagent-grade trichloroethylene shall be used as the reagent required in paragraph 4. Method A shall be followed. The sample shall be taken from the slurry seal sample taken in the field. A 3- to 3.5-lb (1.4- to 1.6-kg) representative sample shall be taken from the sample submitted for testing.

The moisture in the sample shall be tested in accordance with AASHTO T110-88I, Standard Method of Test for Moisture or Volatile Distillates in Bituminous Mixtures, except as designated below. Xylene will be used as the solvent required by paragraph 2.4. Tests listed in Paragraph 6 will be omitted.

The results will be recorded on LTPP Test Sheet H17.
