GEOTECHNICAL SPECIFICATIONS
  Suggested Solite® and Kenlite® Geotechnical Fill Specifications
 
The information listed below is a suggested specification for Solite® and Kenlite® Lightweight Aggregate soil fill. It is best to consult with a Sales Representative during a project's conceptual design phase in order to specify the most appropriate geotechnical material physical properties.


  Materials
 
Lightweight Aggregate fill shall be Solite®, Kenlite® Lightweight Expanded Shale Aggregate or approved rotary kiln produced expanded shale substitute meeting all the requirements of a recently completed (2 years max.) ASTM C 330 certification.  No by‑product slags, coal derived by-product aggregates (cinders, bottom ash, fly ash) or pumice, scoria, tuff are permitted. Lightweight aggregate shall have a proven record of durability and be non‑corrosive (less than 100 ppm chloride when measured by AASHTO T 260) with the following physical properties:

The dry loose unit weight shall be less than 45 pcf (720 kg/m3).  The lightweight aggregate producer shall submit verification of a compacted density of less than 60 pcf (960 kg/m3) when measured by a one point proctor test conducted in accordance with ASTM D 698, "The Standard Test Methods for Moisture - Density Relations of Soils and Soil‑Aggregate Mixtures Using a 5.5 lb. Hammer and 12 inch Drop" (AASHTO T 99).


 
C.

The lightweight aggregate producer shall submit verification that the angle of internal friction shall be greater than 40° when measured in a triaxial compression test on a laboratory sample with a minimum diameter of 10 inches. (ASTM D 698).

 
D.

The maximum Los Angeles Abrasion loss when tested in accordance with ASTM C 131 Modified (B grading) shall be <30%.
