SUBJECT: Soils Compaction Tests on Base Course Material In Street.
Dear Sir:
This report covers our soils compaction tests on Woodland Drive,
Chestnut Manor Subdivision, Carlsbad, California.
Six tests were made on the base course material at locations shown
on the following enclosure titled "Test Locations.
The material tested consisted of decomposed granite shaped to final
grade and compacted by pneumatic roller. The results of our field
density tests Indicate that the material is well compacted and meets
City of Carlsbad requirements.
Basic information on the "Stability of Soils" is reported on the follow-
ing enclosures.
Respectfully submitted,
