P. 0. Box 1155 Carlsbad, California 92008 Attention: Mr., Jerry L. Rombotis DESIGN LAGUNA RIVIERA ESTATES UNIT NO. 4 CEIVED AR 20 '1970 CITY, OF. CARLSBAD Engineering Department In accordance with your letter of August. 8, 1969, we have determined the structural asphaltic pavement section for streets within the subject subdivision. We understand from your letter that the following Traffic 'Index numbersare to be used in design: iz LOation Traffic Index Park Drive 7 Valencia Avenue 5-1/2 Alondra Way and Bienvenida Circle 4-1/2 Representative samples of the proposed subbase soils were secured and submitted to Testing Engineers for "R' Value tests. Laboratory tests including grain size distribution, Atterbera limits, and sand equivalent test were made in our laboratory. Results of these tests are noted on the attached forms. The samples were secured at the following locations: Sample No. Location SK-A Valencia Avenue Opposite Lot 95 SK-B Alondra Way Opposite Lot 122 SK-C • Park Drive Opposite Lot 117 SK-D Park Drive Opposite Lot ill SK-E. Park Drive Opposite Lot 104 The structural asphaltic pavement sections are designed on the basis of '1R" Values of 8 for Valencia Drive, Alondra Way and Bienvenida' Circle. An inspection of the site indicates that soils along Park Drive are, for, the most part, similar to Sample SK-E; therefore, an "R" Value of 10 was used for design. The structural pavement design' were, using the above data, in accordance with Test Method No. Laguna Riviera Estes Unit No 4 Project No. 66-237-4 ..' "• ..:'. Page 'California 501-F, Materials Manual, Division of Highways, State of California. The results of our analysis indicate'that the structural - .. pavement sections should be as follows: Asphalt Concrete Class III Base Thickness-Inches 'Thickness-Inches S Park Drive 3-1/2 - 15-1/2 ' Valencia Drive 2-1/2 3 12-1/2 O/— Alondra Way and 9 Bienvenida Circle I '. ' ' - B' The paving materials should conform to the following-specifications: '(A) Asphaltic Concrete shall be Type A asphaltic concrete conforming to Section 39 of the State of California Standard Specificati'ons, 1964. 5 (B) Aggregate Base 'shall be Class III aggregate base con- • forming to the latest County of San Diego, Special S S Provisions and Specifications for the Improvement of S New Streets. - The above design assumes that the structural pavement sections will be placed on undisturbed native soils or on properly compacted fill soils.
