Long Term Pavement Performance Project Laboratory Materials Testing and Handling Guide

Protocol H03L
Penetration of Bituminous Materials (AE02S)

This LTPP protocol covers the determination of the penetration of asphalt cements at 25°C (77°F). It is intended to be used on asphalt cements extracted from cores recovered from pavements as a part of the SPS-3 studies. The test shall be performed in accordance with AASHTO T49-89I, Standard Method of Test for Penetration of Bituminous Materials, except as designated below. The test shall be conducted at 25°C (77°F). The 50-gram (0.11-lb) weight will be placed on the needle providing a 100-gram (0.22-lb) weight total. Use this test in place of ASTM D5 when necessary. When performing the test in accordance with ASTM D3407-78, use a penetration cone in place of the needle, meeting the requirements established in paragraph 5 of ASTM D3407-78.

The results will be recorded on LTPP Form H02 for SPS-3. The results will be recorded on LTPP Form H15 for SPS-4. Comments shall include LTPP standard comment code(s) as shown in Section 4.3 of this Guide, and any other note as needed. Additional codes for special comments associated with the testing are given below.
