ENVIROSEAL CORPORATION'S ADA TRAIL AND ADA PATHWAY SPECIFICATIONS
FOR THE CONSTRUCTION OF A PATH OR WALK WAY THAT WILL PROVIDE YEARS OF VERY LOW MAINTENANCE / SERVICE
PART 1 - TRAIL / PATH SPECIFICATIONS
1.1 STONE DUST MIX
Crushed Stone Screenings; Trap rock or equal, made of hard, durable, sharp
edged rock fragments, free from dirt or other deleterious matter. Percentages are measured by weight of
dry stone. The Trap rock or equal conform to the following SAE requirements: 100 % by weight passing a ½”
screen 65 to 75 % by weight passing a ¼” Inch screen; less than 2% passing a No 200 sieve (ASTM
5A5) fine aggregate.
Example of screenings passing the below
| 100% |
90 to 100% |
30 to 56% |
30 to 43% |
10 to 20% |
3 to 7% |
5 to 7% |
| ½" |
3/8" |
#4 |
#16 |
#10 |
#100 |
#200 |
Total Depth: The 4” screenings are sufficient for
the trail. It is strongly advised that no sub base of larger crushed stone be used.
The screenings should be placed in a sand bed with very little depth 1”- and given a tack coat prior
to applying the screenings. The depth of the above specified crushed screenings should be (4) four inches
and applied with either a tow behind or powered asphalt spreader.
All Trail Surfaces: should be graded and sloped to allow for drainage. After the
application of the M10+50 the road surface will have best results if a vibratory compactor of 3 to 5 ton
capacity is used to finish TRAIL surface. Save enough M10+50 to make one final pass over the TRAIL surface
after compaction. This procedure will insure a SEMI HARD FLEXIBLE surface TRAIL that has the appearance
of the natural stone and will last for years to come at a fraction the cost of using asphalt or concrete.
1.2 ENVIROSEAL MIX
1. Enviroseal M10+50
as manufactured by Enviroseal Corp, 1019-1021 Holbrook Ct., Port St. Lucie,
FL. 34952 or approved equal.– 800-775-9474 - 772-335-8225, our web page at www.enviroseal.com
email Corp. Sales Department
2. Shall consist of a synthetic acrylic copolymer enhanced
with antibacterial agents, UV Inhibitors and copolymer plasticizers to be diluted with water as per the
on site engineers determination in accordance with available soil moisture.
3. Shall add Enviroseal Co-polymer M10+50 shall be added at
a ratio of from 5.0 gallons per cubic yard in concentrate depending on the end result desired a lighter
mix should be used for loose surface running trails. For the ADA walking trail the higher dosages apply..
The add mix of water dilution as in #2 above and in accordance with the optimum moisture ratios of the stone
mix being used.
4. Shall be clear, natural in appearance, non-toxic, odorless
and environmentally safe.
5. Shall comply with ASTM and EPA Standards and Regulations.
6. Shall be ADA and The National Center for Accessibility
(NCA) recommended / approved / or in compliance with the standards set fort in their specifications.
1.3 SOURCE QUALITY CONTROL
1. Section 01400 - Quality Control: Source testing and analysis
of aggregate material.
2. If test indicates materials do not meet specified requirements
change material or material Source and re-test.
3. Provide materials of each type from same source throughout
the Work.
PART 2 EXECUTION
2.1 EXAMINATION
1. Verify trail base conditions under provisions of
local specification.
2. Verify gradients and elevations of base are correct.
3. Do not prepare or Install material during, prior
to, or immediately following rainfall; or when temp is 45 degrees F and falling.
2.2 PREPARATION
1. If existing an aggregate surface is to remain, grade the
existing material so that an even layer of new material is placed over the entire area then mix the two
together so that a uniform mix is obtained and conforms to the suggested approved criteria as in the above
sieve analysis.
