Long Term Pavement Performance Project Laboratory Materials Testing and Handling Guide

Protocol H14L
Sieve Analysis of Seal Coat Aggregates (SC10)

This LTPP protocol covers the procedures used to determine the size distribution of aggregates for chip seals and slurry seals for use in the H-101 SPS-3 study. The test is to be performed in accordance with AASHTO T27-82 as modified herein. The sieve sizes shall conform to the following:

Chip Seal Slurry Seal
½ in (12.5 mm)
3/8 in. (9.50 mm) 5 /16 in (8.00 mm)
No. 4 (4.75 mm) No. 4 (4.75 mm)
No. 8 (2.36 mm) No. 8 (2.36 mm)
No. 10 (2.00 mm)
No. 16 (1.18 mm)
No. 30 (0.600 mm)
No. 50 (0.300 mm)
No. 100 (0.150 mm)
No. 200 (0.075 mm) No. 200 (0.075 mm)

The results of testing on chip seal aggregates (AGCS) will be recorded on LTPP Test Sheet H16. The results of testing on slurry seal aggregates (AGSL) will be recorded on LTPP Test Sheet H17.
