About this file
This document contains supplemental specifications issued by the U.S. Forest Service for road maintenance aggregate materials to be used under the Federal Lands Highway Program's FP-14 standard specifications. The key details are:
The supplemental specifications provide requirements for subbase, base course, and surface course aggregates, including gradations, physical property limits, and testing methods. The aggregates must meet stringent durability, abrasion resistance, and other quality standards. Screened aggregates are also specified. The document includes replacement tables for the FP-14 aggregate gradation requirements.
This supplemental specification is likely related to a future solicitation for road maintenance or construction services on the Apache-Sitgreaves National Forests. Contractors providing materials for those projects would need to ensure their aggregates meet these supplemental specifications in addition to the base FP-14 requirements.

(a) Subbase or base aggregate. Furnish hard, durable particles or fragments of crushed stone, crushed slag, or crushed gravel conforming the following:
| (1) Gradation | Table 703-2 |
| (2) Liquid limit, AASHTO T 89 | 25 max. |
| (3) Plastic limit, AASHTO T 90 | Nonplastic |

| (8) Fractured faces, ASTM D 5821 | 50% min. |
(9) Free from organic matter and lumps or balls of clay
Do not use material that breaks up when alternately frozen and thawed or wetted and dried.
Obtain the aggregate gradation by crushing, screening, and blending processes as necessary. Fine aggregate, material passing the No. 4 sieve, shall consist of natural or crushed sand and fine mineral particles.
(b) Surface course aggregate. Furnish hard, durable particles or fragments of crushed stone, crushed slag, or crushed gravel conforming the following:
| (1) Gradation | Table 703-3 |
| (2) Liquid limit, AASHTO T 89 | 35 max. |
(3) Plastic Index, AASHTO T 90
| a) If the percent passing the No. 200 sieve is less than 12% | 2 to 9 | ||
| b) If the percent passing the No. 200 sieve is greater than 12% | Less than 2 | ||
