Amended NIFC Campus Seal Coat 24AUGUST2023

PART 1 – GENERAL INFORMATION

A. Summary: The Bureau of Land Management, National Interagency Fire Center

(NIFC), located at 3833 S. Development Avenue, Boise, Idaho, has a requirement for an application of asphalt slurry seal applied to the existing asphalt concrete pavement surface to renew and seal the surface. Following the asphalt slurry seal process, line striping will be performed to re-stablish the campus parking and roadway areas. This document specifies the characteristics of the material and details the application workmanship.

B. The campus surface parking is comprised of asphalt concrete (AC) surfacing in a combination of parking lots and roadways. The AC surfacing has received miscellaneous patches and sealcoat throughout the years with no formal materials used.

C. Work will be done throughout the campus over 90 consecutive days to allow

Government to move vehicles and equipment from one area to the next. Contractor will coordinate with COR to ensure government vehicles and equipment are moved.

D. Administration: Overall administration of this contract shall be by the Contracting

Officer (CO). The CO will appoint a Contracting Officer Representative (COR) to manage the detailed activities of the contract.

E. Installer qualifications: Work shall be accomplished by companies demonstrating 5 years of sealcoating experience in the State of Idaho.

F. Description: The slurry seal shall consist of a mixture of an approved emulsified asphalt, mineral aggregate, water, and specified additives, proportioned, mixed and uniformly spread over a properly prepared surface as directed by the COR. The completed slurry seal shall leave a homogeneous mat, adhere firmly to the prepared surface, and have a friction-resistant surface texture throughout its service life.

G. SUBMITTALS:

1. Contractor shall submit product data to the Government for review. Submit package a minimum of 1 week prior to scheduled work start date. Allow

Government 7 business days to review. Contractor shall not proceed with replacement until receipt of reviewed submittals from the government.

2. Submittal Package shall include:

(a) Asphalt slurry seal materials: emulsified asphalt type and grade, aggregate, anti-strip additives, cover coat material.

(b) Test results for testing indicated.

(c) Pavement paint manufacturers certification that paints and beads meet or exceeds specified requirements.

(d) Project Schedule, describing at a minimum; start date, work schedule for each parking lot/roadway, weekend and holiday work expected and total project length.

The use of additives in the slurry mix (or individual materials) shall be made initially in quantities predetermined by the mix design with field adjustments approved by COR.

E. AGGREGATE MATERIAL

1. Furnish Aggregate cover material consisting of crushed or uncrushed Rock free of Clay, loam or other harmful substances and meeting the following gradation. Sieve analysis will be determined according to ASTM D75.

PART 3 – EXECUTION

A. GENERAL

1. Complete all work in each section as indicated by the individual sheet before moving onto the next section. Refer to the Drawings.

B. CONSTRUCTION LIMITATIONS

1. Do not apply when roadway surface or weather conditions would prevent satisfactory construction.

2. Weather Limitations: Do not place when the air temperature is below 55℉ and falling, but may be applied when both pavement and air temperatures are above

45℉ and rising.

3. No slurry seal shall be applied when there is danger that the finished product will freeze before 24 hours.

4. Do not place when pavement temperatures exceed 140°F.

5. Do not place when wind velocity exceeds 15 mph.

C. SCHEDULING

1. Prior to moving to next scheduled area of work, contractor to notify COR to confirm work is complete and ready to accept traffic.

D. EQUIPMENT

1. Mixing Equipment

The machine shall be specifically designed and manufactured to lay slurry seal.

The material shall be mixed by a self-propelled, slurry seal mixing machine of either truck-mounted or continuous-run design.

2. Proportioning Devices

Individual volume or weight controls for proportioning each material to be added to the mix (i.e. aggregate, mineral filler, emulsified asphalt and additive) shall be provided and properly marked.

3. Spreading Equipment

The mixture shall be spread uniformly by means of a conventional surfacing spreader box attached to the mixer and equipped to agitate and spread the material evenly throughout the box. A front seal shall be provided to insure no loss of the mixture at the road contact point. The rear seal shall act as final strike-off and shall be adjustable. The spreader box and rear strikeoff shall be so designed and operated that a uniform consistency is achieved to produce a free flow of material to the rear strike-off. The spreader box shall have suitable means provided to side shift the box to compensate for variations in the pavement geometry. A burlap drag or other approved screed may be attached to the rear of the spreader box to provide a uniform, highly textured mat.

E. REPAIRS

1. Crack and Joint Filling: Remove existing joint filler material from cracks or joints to a depth of 1/4 inch.

a) Clean cracks and joints in existing hot-mix asphalt pavement.

b) Use emulsified-asphalt slurry to seal cracks and joints less than 1/4 inch wide. Fill flush with surface of existing pavement and remove excess.

c) Use hot-applied joint sealant to seal cracks and joints more than 1/4 inch wide. Fill flush with surface of existing pavement and remove excess.

F. EMULSIFIED-ASPHALT SLURRY SEAL

1. Clean surfaces with powered vacuum sweeper and high-pressure water as required to meet conditions. Do not begin applying asphalt until surface is completely dry and has been approved by Engineer.

2. Protect all drains, utilities and manhole covers by covering with building paper prior to spreading asphalt.

2. Care shall be exercised to leave no unsightly appearance from handwork. The same type finish as applied by the spreader box shall be required. Handwork shall be completed during the machine applying process.

H. LINES

1. Care shall be taken to measure straight lines along curbs and shoulders. No run-off on these areas will be permitted. Lines at intersections will be kept straight to provide good appearance.

I. ROLLING

1. Parking areas should be rolled by a self-propelled, 5-ton pneumatic roller with a tire pressure of 50 PSI (3.4 ATMS), equipped with a water spray system. The surfaced areas shall be subjected to a minimum of two (2) full coverage passes by the roller.
