Dispose of unsuitable and excess material according to the specified method(s) as follows:

(a) Windrowing Construction Slash. Place construction slash outside the roadway in neat, compacted windrows approximately parallel to and along the toe line of embankment slopes. Do not permit the top of the windrows to extend above subgrade. Use construction equipment to matt down all material in a windrow to form a compact and uniform pile. Construct breaks of at least 15 feet at least every 200 feet in a windrow. Do not place windrows against trees.

(b) Scattering. Scatter construction slash in designated areas without damaging trees. Limb all logs. Place logs and stumps away from trees, positioned so they will not roll, and are not on top of one another. Limb and scatter other construction slash to reduce slash concentrations. When scattering for erosion control, place construction slash as flat as practicable on the completed slope.

(c) Chipping. Use an approved chipping machine to chip slash longer than 3 feet. Deposit chips on embankment slopes or outside the roadway to a loose depth less than 6 inches. Minor amounts of chips or ground woody material may be permitted within the roadway if they are thoroughly mixed with soil and do not form a layer.

(d) Debris Mat. Use tree limbs, tops, cull logs, split stumps, wood chunks, and other debris to form a mat upon which construction equipment is operated. Place stumps upside down and blend stumps into the mat.

(e) Decking. Remove brush from designated log deck areas. Limb and top logs.

Logs not meeting the Utilization Standards described in Subsection 201.04(c) shall be cut to lengths less than (fill-in) feet and decked in designated log deck location.

Merchantable timber not associated with an existing timber sale shall be cut to length meeting the Utilization Standards described in Subsection 201.04(c).

Deck logs so that logs are piled parallel to one another; can be removed by standard log loading equipment; will not damage standing trees; will not interfere with drainage, and will not roll. Keep logs in log decks free of brush and soil.

(f) Removal to designated locations. Remove construction slash to designated locations.

(g) Piling. Pile construction slash in designated areas. Place and construct piles so that if the piles are burned, the burning will not damage remaining trees. Keep piles free of dirt from stumps.

Section 399 – Trail Surface Aggregate

399.01 Definition.

This section is for the purchase and placement of Trail Surface Aggregate (TSA) for the Green Mountain National Forest. TSA is an aggregate mixture of crushed stone designed specifically as a surface-wearing course for unpaved tails.

399.02 Material.

All Trail Surface Aggregate (TSA) is to be derived from natural stone formations. Stone is defined as rock that has been crushed; rock is defined as consolidated mineral matter. All components of the aggregate mix are to be derived from crushed rock material that meets specifications below for abrasion resistance, pH and freedom from contaminants. Material must meet the following requirements:

1. Gradation: The required sieve sizes and allowed ranges, determined by weight, for TSA components are shown in Table 1.

Table 1 – TSA Gradations

1. Abrasion Resistance: The loss of mass (LA Abrasion) shall be less than 40%. Determine the resistance to abrasion using the Los Angeles Abrasion test, AASHTO T-96 (ASTM C131).

1. pH: Aggregate shall be in the range of pH 6 to pH 12.45 as measured by EPA 9045C

1. Moisture: Material is to be delivered and placed at optimum moisture content +/- 1% as determined for that particular source. The optimum percentage moisture is to be determined using Proctor Test ASTM D698, Standard.

1. Plasticity: Material shall not exceed a Plasticity Index (PI) of 6. The laboratory test required for these results is ASTM D4318 – Standard Test Method for Liquid Limit, Plastic Limit, and Plasticity Index of Soils.

1. Aggregate: All DSA shall be derived from natural rock formations that meet program specification for abrasion resistance, pH and freedom from contaminants.

1. Fines: The fines passing the #200 sieve must be rock material. No clay or silt soil may be added. Limestone material passing the #200 sieve may be used to make up a deficit in the distribution of sandstone aggregate rock, and vice versa. All added material passing the #200 sieve must be derived from rock material that conforms to program specifications. Lime kiln dust and cement kiln dust may be added to DSA to account for up to 50% of the fines passing the #200 sieve. The amount of particles passing the #200 sieve shall be determined using the washing procedures specified in PTM No. 100.

399.03 Delivery & Placement.

1. Preparation of Base: Base shall be prepared and compacted in accordance to the plans and specifications.

1. Placement: TSA shall be placed and shaped as shown in the plans. Compact each layer full width. Roll from the sides to the center, parallel to the centerline of the road. Along curbs, headers, walls, and all places not accessible to the roller, compact the material with approved tampers or compactors. Compact the aggregate using one of the following methods as specified: Operate rollers and compact as specified in Subsection 204.11(a)(1).

399.04 Acceptance.

Acceptance will be evaluated under Subsections 106.02 and 106.04.

399.05 Payment.

The accepted quantities will be paid at the contract price per unit of measurement as listed in the bid schedule. Payment will be full compensation for the work prescribed in this Section. See Subsection 109.05.
