DIVISION 1 SHORT FORM GENERAL REQUIREMENTS

PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: The CVNP Ohio & Erie Canal towpath trail is used by over 1.5 million visitors annually and accounts for 67% percent of total visitation of the park. It is the defining cultural resource for Cuyahoga Valley National Park and the Ohio & Erie Canal National Heritage Corridor. The Park’s towpath trail is aligned directly over the historic mule path that conveyed barges through the historic canal system. Addressing the issues outlined in this project protects the historic mule path, the historic canal, and the adjoining natural resource of the Cuyahoga River that runs within close proximity to this historic path. The current Towpath surface needs to be stabilized and more sustainable to eliminate safety problems such as rutting and wash boarding that has contributed to visitor bicycle and jogging accidents. Stabilizing the existing surface with a more sustainable material will also reduce dust which can affect all users visibility which also causes accidents. Being that this section of the Towpath is in such a remote area, sustainability of this trail is vital to the safety of our visitors. With a more sustainable surface our maintenance staff will not need to visit this location as frequent and can keep maintenance vehicles off the Towpath away from the visitors. It will also provide a safer uniform trail surface which is consistently used by families with small children.

1.2 Work Covered by the Contract Documents:

A. Project Location: Cuyahoga Valley National Park, Station Road Bridge Trailhead – 9141 Riverview Rd, Brecksville, OH 44141

Page | 3

B. Work consists of: Repairing multiple sustainable surfaces along several sections of the

Towpath Trail. The images in the photograph section of this document above give a good visual of what is explained here.

1. Section A: Starting at the 4-way intersection of Station Road and the

Towpath Trail and heading North. The existing paved section will have chip + seal added to the surface for the entire length of approximately 650

ft. This section ends at the bridge of the Cuyahoga River feeder gate bridge and section B begins.

2. Section B: Starts at the Cuyahoga River feeder gate bridge and heading

North. The old pavement is in a severely hazardous condition. This section is approximately 2,400 ft in length and will be finished at a width of no less than 8 feet wide, not to exceed 9 feet. This will need grinded down to a level base that will allow for a 4” asphalt overlay that matches the grade of Section A chip + seal. The binder course should be 2.5” and the finish lift will be 1.5”. The surface for section B will also be finished with chip + seal. This is the only section that will be grinded deep enough to allow a 4” overlay. This section B specifically needs the thicker pavement to provide a more sustainable pavement surface since this area is sometimes used by dump trucks to dredge the canal. Add topsoil, grass seed, and straw to both berms on pavement edges to blend to existing grade.

3. Section C: Starting where the horse trail splits from the towpath trail at the end of Section B, remove any debris or vegetation from the existing base course at a width of approximately 8’, then have 2-inches of ODOT

703.10 Limestone screenings installed and compacted overtop the existing screened surface to an approximate width and length of 8 feet x 3,200 feet.

4. Section D: Beginning where the horse trail merges back onto the towpath at the end of section C. This section will be grinded to allow a level base and overlayed with 2.75” of asphalt and finished with chip + seal. This section is approximately 675 feet in length and will be finished at a width of no less than 8 feet wide, not to exceed 9’. The paved sections of the Towpath are applied to the areas that the horse trail merges onto the path to allow for a more sustainable surface with horse and pedestrian traffic.

Add topsoil, grass seed, and straw to both berms on pavement edges to blend to existing grade.

5. Section E: Starting where the horse trail splits from the towpath trail at the end of Section D, remove any debris or vegetation from the existing base course at a width of approximately 8’, then have 2-inches of ODOT

703.10 Limestone screenings installed and compacted overtop the

1,900 feet.

Page | 4

6. Section F: Beginning where the horse trail merges back onto the towpath at the end of section E. This section will be grinded to allow a level base and overlayed with 2.75” of asphalt and finished with chip + seal. This section is approximately 1,950 feet in length and will be finished at a width of no less than 8 feet wide, not to exceed 9’. The paved sections of the Towpath are applied to the areas that the horse trail merges onto the path to allow for a more sustainable surface with horse and pedestrian traffic.

7. Section G: Starting where the horse trail splits from the towpath trail at the end of Section F, remove any debris or vegetation from the existing base course at a width of approximately 8’, then have 2-inches of ODOT 703,10 Limestone screenings installed and compacted overtop the existing screened surface at a width of 8 feet x approximately 1,600 feet in length.

8. Section H: Beginning where the horse trail merges back onto the towpath at the end of section G. This section will be grinded to allow a level base and overlayed with 2.75” of asphalt and finished with chip + seal. This section is approximately 600 feet in length and will be finished at a width of no less than 8 feet wide, not to exceed 9’. The paved sections of the Towpath are applied to the areas that the horse trail merges onto the path to allow for a more sustainable surface with horse and pedestrian traffic.

9. Section I: Starting where the horse trail splits from the towpath trail at the end of Section H, remove any debris or vegetation from the existing base course at a width of approximately 8’, then have 2-inches of ODOT 703,10 Limestone screenings installed and compacted overtop the

1,600 feet.

10. Section J: Beginning where the horse trail merges back onto the towpath at the end of section I. This is labeled as one section but is broken down into three areas on the photograph attached for Section J above. The specs are the same for each area, there is only a break in the pavement due to a bridge that does not get paved and a concrete spillway that will not have surface work. These sections will be grinded to allow a level base and overlayed with 2.75” of asphalt and finished with chip + seal.

This section is approximately 250 feet in length and will be finished at a width of no less than 8 feet wide, not to exceed 9’. These areas have approaches to trail features and need to match the grade of the existing pavement to allow for a smooth transition to bridge tread and the spillway.

PART 3 - EXECUTION

3.1 SITE CLEARING

Remove slabs, paving, curbs, gutters, and walks as indicated.

1. Unless existing full-depth joints coincide with line of demolition, neatly saw-cut along line of existing pavement to remain before removing adjacent existing pavement. Saw-cut faces vertically.

Remove sod and grass before stripping topsoil. Contractor to identify and determine depth of existing topsoil. Strip topsoil in a manner to prevent intermingling with underlying subsoil or other waste materials.

2. Stockpile topsoil away from edge of excavations without intermixing with subsoil or other materials. Grade and shape stockpiles to drain surface water. Cover to prevent windblown dust and erosion by water.

3. Dispose of surplus topsoil. Surplus topsoil is that which exceeds quantity indicated to be stockpiled or reused.

Remove surplus soil material, demolished materials, and waste materials including trash and debris, and legally dispose of them off Government’s property.

3.2 EXAMINATION

Verify that subgrade is dry and in suitable condition to begin paving.

Div. 32 V. 2021-10-18 ASPHALT PAVING 321216 Page | 5

Proceed with paving only after unsatisfactory conditions have been corrected.

3.3 PREPARATION

Protection: Provide protective materials, procedures, and worker training to prevent asphalt materials from spilling, coating, or building up on curbs, driveway aprons, manholes, and other surfaces adjacent to the Work.

Proof-roll subgrade below pavements with heavy pneumatic-tired equipment to identify soft pockets and areas of excess yielding. Do not proof-roll wet or saturated subgrades.

1. Completely proof-roll subgrade in one direction, repeating proof-rolling in direction perpendicular to first direction. Limit vehicle speed to 3 mph.

2. Proof-roll with a loaded 10-wheel, tandem-axle dump truck weighing not less than 15 tons.

3. Excavate soft spots, unsatisfactory soils, and areas of excessive pumping or rutting, as determined by COR, and replace with compacted backfill or fill as directed.

Proceed with installation only after unsatisfactory conditions have been corrected.

3.4 COLD MILLING

Clean existing pavement surface of loose and deleterious material immediately before cold milling. Remove existing asphalt pavement by cold milling to grades and cross sections indicated.

1. Mill to a depth of 2.75 inches.

2. Mill to a uniform finished surface free of excessive gouges, grooves, and ridges.

3. Control rate of milling to prevent tearing of existing asphalt course.

4. Repair or replace curbs, driveway aprons, manholes, and other construction damaged during cold milling.

5. Excavate and trim unbound-aggregate base course, if encountered, and keep material separate from milled hot-mix asphalt.

6. Patch surface depressions deeper than 1 inch after milling, before wearing course is laid.

7. Keep milled pavement surface free of loose material and dust.

8. Do not allow milled materials to accumulate on-site.

3.5 SURFACE PREPARATION

Ensure that prepared subgrade has been proof-rolled and is ready to receive paving.

Immediately before placing asphalt materials, remove loose and deleterious material from substrate surfaces.

Tack Coat: Apply uniformly to surfaces of existing pavement at a rate of 0.05 to 0.15 gal./sq. yd.

1. Allow tack coat to cure undisturbed before applying hot-mix asphalt paving.
