MANUFACTURER SPECIFICATIONS

Use of an Asphalt Rejuvenator Emulsion of Bituminous Pavements

1.0 SCOPE:

This work shall consist of furnishing all labor, material, and equipment necessary to perform all operations for the application of the rejuvenator to the surface of bituminous pavements as a preservative seal. The rejuvenation of surface courses shall be by spray application of a bio-based rejuvenating agent composed of naturally derived products with the exception of polymer modification, emulsified with water. All work shall be in accordance with the requirements, the applicable drawings, and subject to the terms and conditions of these specifications.

2.0 MATERIAL SPECIFICATIONS:

The asphalt rejuvenating emulsion shall be composed of a bio-base product uniformly mixed with water and equipment to continuously mix. Each bidder must submit with their bid a certified statement from the rejuvenator manufacturer showing that the rejuvenating emulsion conforms to the requirements below:

Specific Gravity ASTM E-100-17 0.92-0.95

Residual, w% ASTM 244 (Mod1) 25-35

Appearance Milky/White 1ASTM 244 Evaporation Test for percent residue is performed by heating a 50 gram sample to 100ºC for 2 hours while agitating, then raising the temperature to 149ºC (300ºF) for an additional hour, and calculating results.

*Water dilution shall be performed with potable water 1:1 by volume adding water to the concentrate

3.0 MATERIAL PERFORMANCE & TEST SECTIONS:

The rejuvenating agent shall have a record of satisfactory service as an emulsified asphalt rejuvenating agent and in-depth sealer. Satisfactory service shall be based on the capability of the material to decrease the viscosity of the asphalt binder as follows. The viscosity shall be reduced by a minimum of 30% for pavements less than or equal to 3 years old and 40% for pavements greater or equal to 4 years old. The rejuvenating agent shall not harm pavement striping so restriping is not required.

The bidder must submit with his bid the manufacturer's certification that the material proposed for use is in compliance with the concentrated rejuvenating agent requirements and the diluted emulsion requirements.

The bid submittal must include documentation of previous use and test data conclusively demonstrating that the rejuvenation product has been used successfully; and that the construction joint rejuvenation product has been proven to perform in a manner equivalent to above performance specification, through third party testing and/or agency use showing the required change in the recovered asphalt binder properties.

The agency, at their option, may require testing to be performed to determine the rejuvenator’s effect on the pavement. An untreated sample can be removed prior to treatment or taken from a small section that was left untreated to allow all cores to be taken at the same time. Treated cores should be taken 30-90 days after treatment. This is typical time frame but can be modified if needed. The top 3/8” of each core shall be removed for testing. The asphalt binder shall be extracted and recovered from this portion of the core using Caltrans Test Method (CTM) 365.

Viscosities are then determined on the recovered asphalt binder using a sliding plate microviscometer (CTM 348) or Dynamic Shear Rheology (AASHTO T315). Penetrations are calculated from a nomograph. The percent decrease for viscosity or percent decrease in DSR values shall be calculated to show the effect of the rejuvenator.

BIORESTOR® Asphalt Rejuvenator Emulsion as manufactured by BioBased Spray Systems, LLC is a product of known quality and accepted performance.

4.0 APPLICATOR EXPERIENCE:

The asphalt rejuvenating concentrate shall be received and diluted by the end applicator, 1:1 by volume. The asphalt rejuvenating emulsion agent shall be applied by an experienced applicator of such material. A project superintendent knowledgeable and experienced in application of the asphalt rejuvenating agent must be in control of each day's work. Prior knowledge of traffic control, traffic management, and traffic safety is required. Applicator shall have had training on spray system set up, maintenance, application rates, and proper storage.

Disruption of traffic flow must be held to a minimal amount of time. Traffic must not be allowed onto the roadway until rejuvenating agent has cured. Approximately 30-60 minutes.

5.0 PREPARATION AND APPLICATION

Applicator is responsible for sweeping and cleaning of asphalt prior to treatment. All dirt, leaves, standing water, foreign material, etc. shall be removed. Self-propelled sweepers or high volume power-blowing equipment provides the applicator with a sufficient pavement conditions.

Product will be shipped and delivered to end user as a concentrate. Product shall be applied as a rejuvenator emulsion diluted 1:1 by volume by the applicator. Rate of application for the entire asphalt pavement is stated at 0.02 gal/sq. yd. for asphalt 3 years or newer, and 0.03 gal/sq. yd. for asphalt older than 3 years. Construction joint treatment with the emulsion is stated as 0.03 gal/sq.

yd. for new pavements but possibly up to 0.04 gal/sq. yd. depending on age and type of service.

Pavements with low air void or high density (94+) are not recommended as good candidates for rejuvenation. For optimal results consult with a pavement preservation engineer professionals prior to application.

Pavement surface temperatures is recommend to be 50ºF and rising for optimal drying time.

Treated sections of pavement shall be kept free of traffic until penetrated and cured. Typically between 30-60 minutes in ideal conditions, with weather and pavement conditions determining these time factors. Cure time varies on many factors including: Outside temperature, sunlight, pavement density, pavement age, ect. Traffic control shall be in accordance with local, state and federal requirements.

NOTE: Sanding may be applicable for denser pavements, aged pavements, raveled asphalt or to allow for treated area to be open to traffic quicker at a controlled speed.

6.0 PRODUCT STANDARDS:

The product "BIORESTOR® Asphalt Rejuvenator Emulsifable Concentrate" as previously manufactured by BioBased Spray Systems, LLC is the standard concentrate to be emulsified with water 1:1. BIORESTOR® Asphalt Rejuvenator Emulsion applied by the applicator, is the standard for the asphalt rejuvenating emulsion agent requirements and the prices quoted on the bid sheet base bid shall be for one of these standards.
