Gentlemen:
Per our conversations with Doug Woods of T. & G. Investments and
Dan Clark of the City of Carlsbad, we are providing additional
pavement recommendations for Loker Avenue East, Sea Lion Road,
and Sea Otter Road. The recommended sections are presented on
Table I. The calculations are attached.
We recommend that the upper')- 12 inches of pavement subggrade
soils be scarified, moistened to near optimum conditions and
compacted to a minimum 95 percent of ASTM D1557.
Specifications for Class II Base should be taken from CALTRANS
Section 26-1.02B. We recommend that you require the contractor
or supplier to assure conformance with specifications. In
addition, we recommend that testing be performed prior to placing
base or subbase materials. It should be noted that testing may
require 5 to 7 days. We recommend that all aggregate base and
subbase be compacted to 95 percent of ASTM D1557.
