615.01 Description of Work

The work shall consist of removal and disposal of approximately 5,280 Lf. of existing asphalt pavement and sub base material. Construction of an ADA accessible trail having a clear tread width of not less than 60 inches, utilizing a crushed aggregate pavement which includes: trail realignment, clearing and grubbing; excavation and embankment; removing slough and berms;

filling ruts and holes; reshaping back slopes; slope rounding; constructing lead out ditches;

providing a finished trail subgrade tread, an aggregate base course, ADA compliant surface course and trail edging.

615.02 General Construction

Vegetative Removal - Systemic herbicide shall be applied, as per manufacturer's instructions, to all weeds and grasses within trail alignment to ensure that they be removed/killed completely before any construction on top of existing trail.

Subgrade Preparation - Prior to placing any pavement, shape, fill, grade, and compact the subgrade, to ninety-five percent (95%) Standard Proctor Density. The base shall be four inches (4") of compacted CA-6 crushed stone base on a dry natural or compacted subgrade. Where excavation to the finished grade elevation results in sub grade of unsuitable soil, the unsuitable material shall be removed and replaced with approved materials. Approved material for backfilling shall be aggregate base course, or other material approved by the Contracting Officer

(CO).

Placing Crushed Aggregate - Place the crushed aggregate on prepared subgrade, and rake smooth using a steel fine rake to desired grade and cross section. Place, to avoid segregation, in one layer of four inches (4”) maximum thickness. Do not apply deeper than four inches (4”) in one lift.

Backfilling - Backfill excavation to trail edge with scraper spoils, using backfill to hold edge of crusher fines in place.

Compaction - Immediately compact aggregate into smooth, firm surface with self-propelled, vibratory roller of sufficient weight. Maintain proper moisture content per proctor submitted by the Contractor. Rolling shall continue until all material is firmly locked and keyed together. The appearance and surface shall be uniform smooth with all ridges, waves, ruts, holes, and dips removed. Surface shall not vary more than one-half inch (½”) when measured with a ten foot (10’) straight edge applied parallel to the centerline. Correct any variation by loosening, reshaping, and re-rolling. When finished, compacted trail shall be a minimum of four inches (4”) deep in all locations.

In any areas where there are underground pipes, use extreme caution when compacting trail to protect pipe. Discuss alternative compaction methods with the Contracting Officers Representative (COR) prior to execution for approval if pipe hazard is anticipated.

Finishing - At completion of surfacing, remove excess spoils from along trail edge and deposit on site as directed by Contracting Officers Representative (COR).

Rake along all trail edges to ensure finished appearance and positive drainage away from trail.

Inspection - Finished surface shall be smooth, uniform, and solid. Dried, compacted pavement material shall be firm all the way through with no spongy areas. Loose material shall not be present on the surface.

Unconsolidated areas shall be dug out, and replaced with new crushed screenings with a high proportion of fines meeting the grading requirements. Patched areas then shall be wetted thoroughly and rolled smooth. Patching shall be completed prior to any pavement smoothing required.

Significant irregularities shall be smoothed out prior to final acceptance of work. Smoothing shall be accomplished by rewetting/saturating rough areas thoroughly, and rolling the trail with a heavy roller (1,000 - 1,500 pounds powered walk-behind or small rider). Wackers are not acceptable.

Final thickness of completed pavement shall not vary more than ½ inch from dimension indicated. Measurements shall be taken by means of test holes taken at random locations in the finished trail surface. Correct any variations in the thickness beyond the allowable ½ inch by repeating the installation.

615.03 Submittals

Submit four (4) copies of each of the following:

Crushed Aggregate Pavement

a. Submit sieve analysis of material to ensure it meets grading requirements.

b. Submit sample of crushed aggregate screenings for approval, one-half (½) cubic foot.

c. Sieve analysis of crushed aggregate screenings shall be approved in writing by the Contracting Officer (CO) prior to delivery of any material to the project site.

Prepare a sample finished pavement section of each pavement type. Sample section shall be full width of pavement, with length equal to three (3) times the width. The Contracting Officer (CO) prior to final placement of the entire paving shall approve sample pavement section in writing.

Delivery, Storage, and Handling

Protect all materials from damage during delivery and storage.

Product Conditions

Use lightweight hauling equipment. Exercise care in using equipment, avoiding damage to existing structures.

Review installation procedures and coordinate aggregate paving work with other work affects.

All hard surface paving, including concrete walks and asphalt paving must be completed prior to installation of aggregate paving.

Cold Weather:

1. Do not use frozen materials or materials mixed or coated with ice or frost.

2. Do not build on frozen work or wet, saturated or muddy subgrade.

Protect partially or fully completed paving against damage from any traffic when work is in progress, curing, maturing, and settling until substantial competition. Any barricade constructed must still be accessible by emergency and fire equipment during and after installation.

Protect adjacent work and surfaces from damage during porous unit paving installation.

615.04 Materials

Crusher Fines Screenings - Clean, hard, durable particles or fragments of ¼ inch minus select brown/gray crushed granite or local available compatible material. Fines shall be evenly mixed throughout the aggregate. When produced from gravel, fifty percent (50%) by weight, of the material retained on a Number four (4) sieve shall have one fractured face.

The portion retained on the Number four (4) sieve shall have a maximum percentage of wear of fifty (50) at five hundred (500) revolutions as determined by AASHTO T96-77

The portion passing a Number forty (40) sieve shall have a maximum liquid limit of twenty-five

(25) and a maximum plasticity index of seven (7), as determined by AASHTO T89-81, respectively.

The crushed aggregate screenings shall be free from clay lumps, organic matter, and deleterious material.
