5.1 Description

The work specified in this section shall consist of furnishing all labor, material, and equipment necessary to perform all operations for the application of a penetrating asphalt rejuvenating emulsion with photocatalytic titanium dioxide to asphaltic concrete surface courses to create a pollution reducing and solar reflectant pavement surface. See Attachment VII for the list of streets to be included for application.

The rejuvenation of surface courses shall be by spray application of a petroleum maltene based cationic rejuvenator/pollution remediating emulsion composed of petroleum oils and resins emulsified with water and containing photocatalytic titanium dioxide nanoparticles in a minimum parts per million at a specified depth as hereafter required.

All work shall be in accordance with the specifications, the applicable drawings, and subject to the terms and conditions of this contract.

Two bid alternates are listed for proposal. Proposers must submit pricing on both alternates to be considered.

5.2 Material Specifications

Asphalt Rejuvenator:

The asphalt rejuvenating/pollution remediating emulsion shall be composed of a petroleum resin oil base uniformly emulsified with water.

Each bidder must submit a bid with a certified statement from the asphalt rejuvenator manufacturer showing that the asphalt rejuvenating emulsion conforms to the required physical and chemical requirements.

The asphalt rejuvenating emulsion shall have a record of satisfactory service as an asphalt rejuvenating emulsion and in-depth sealer. Satisfactory service shall be based on the capability of the material to decrease the viscosity of the asphalt binder through the maltene replacement technology method. The asphalt rejuvenating emulsion shall cause a positive increase in the maltene content as a percent of the total volume of binder components as determined by laboratory analysis using testing conforming to ASTM D-2006-70 and provide an in-depth seal to the intrusion of air and water.

The bidder must submit with his bid the manufacturer's certification that the material proposed for use is in compliance with the specification requirements. The bidder must submit with his bid previous use documentation and test data conclusively demonstrating that; the asphalt rejuvenating emulsion has been used successfully for at least five years and that the asphalt rejuvenating emulsion has been proven to perform, as heretofore required, through field testing as to the required change in asphalt binder rheology.

Photocatalytic Titanium Dioxide:

Additionally, the asphalt rejuvenating emulsion, serving as a carrier liquid for titanium dioxide, shall contain catalytic titanium dioxide Nanoparticles in an amount that will impregnate the asphalt pavement to a minimum depth of six (6) millimeters analyzed in two (2) millimeter increments with an average of a minimum of 2000 parts per million catalytic anatase titanium dioxide Nano particles. The described material blend shall hereafter be referred to as the asphalt rejuvenating/pollution abating emulsion.

The titanium dioxide shall be of the anatase type that has been shown to photo catalyze the oxidation of atmospheric pollutants such as oxides of nitrogen (NOx) and volatile organic compounds (VOCs). The photocatalytic titanium dioxide shall be of a n-type semiconductor containing 99.5% TiO2 content comprised of no less than 80% anatase crystallite by weight (plus or minus5%) in a particle size averaging 20nm to 25nm (plus or minus 3nm) with a small portion of rutile crystalline content.

The Bidder must submit with his bid test data from an accredited testing laboratory or qualified university research study indicating that the product proposed for use meets the forgoing requirements.

The Engineer may require treated core samples to be removed from the treated pavement fifteen to thirty days following application of the asphaltic rejuvenating/pollution abating emulsion and tested for asphalt binder rheology adjustment and percentage of pollution reduction. If directed, said testing shall indicate asphalt binder improvement as subsequently specified and the percent of NOx gas reduction and TiO2 Nano-particle impregnated at depth specified. The cores shall be tested by an accredited testing laboratory or university capable of testing the core for depth and amount of Titanium Nanoparticle distribution and required NOx gas reduction capability.

5.3 Material Performance

The asphalt rejuvenating emulsion segment of the asphalt rejuvenating/pollution abating emulsion shall penetrate the asphalt pavement surface. The asphalt rejuvenating emulsion shall be absorbed and incorporated into the asphalt binder.

Verification that said incorporation of the asphalt rejuvenating emulsion into the asphalt binder has been affected shall be by analysis of the chemical properties of the asphalt binder rheology, when directed by the Engineer.

The viscosity shall be reduced by a minimum of 20% for a pavement two years or less in age or for pavements previously treated with the rejuvenator and reduced by a minimum of 30% for a pavement greater than two years in age as determined by dynamic shear rheometer (DSR) method for asphalt testing in accord with AASHTO T315-05. This analysis shall apply to extracted asphalt binder, taken from cores extracted fifteen to thirty days following application, from the upper 3/8 inch of pavement. Said viscosity reduction shall be the average of a sampling of the total treated area. In addition, the treated areas shall be sealed in-depth to the intrusion of air and water.

For use in the afore described testing untreated and treated core samples, a minimum of four inches in diameter, shall be removed by the Contractor at locations indicated by the Engineer. The treated core sample shall be taken in the same lane in close proximity to each untreated sample. When directed by the Engineer, a minimum of one untreated and treated core for each test method shall be taken for each pavement type group or one per 30,000 square yards of treated pavement in each pavement type group.

The pollution abating emulsion segment of the asphalt rejuvenating/pollution abating emulsion shall penetrate the asphalt pavement surface. The emulsion shall penetrate the pavement a minimum of six (6) millimeters carrying the titanium dioxide Nano-particles at an average distribution of 2000 parts per million. Verification of said uniform distribution shall be by analysis at a six (6) millimeter depth in three two (2) millimeter increments using XRF analyzer method. The foregoing shall be performed on additional core samples extracted for this purpose from treated and untreated pavement as heretofore outlined and will have a testing frequency as directed by the Engineer.

The NOx pollution reduction performance shall be verified from cores extracted for this specific evaluation from treated and untreated pavements also as heretofore outlined. The procedure shall be based on the Japanese standard JIS TRT Z 0018 “Photocatalytic materials – Air purification test procedure” ISO equivalent 22197-1.

The minimum reduction in NO2 shall be an average of 25% for all cores evaluated.

5.4 Application Equipment

5.4.1 Asphalt Distributor

The distributor for spreading the emulsion shall be self-propelled and shall have pneumatic tires. The distributor shall be designed and equipped to distribute the asphalt rejuvenating agent uniformly on variable widths of surface at readily determined and controlled rates from 0.04 to 0.08 gallons per square yard of surface, and with an allowable variation from any specified rate not to exceed 5 percent of the specified rate.

Distributor equipment shall include full circulation spray bars; pump tachometer, volume measuring device and a hand hose attachment suitable for application of the emulsion manually to cover areas inaccessible to the distributor. The distributor shall be equipped to circulate and agitate the emulsion within the tank.

The rate of application shall be controlled by an onboard computer control system designed to uniformly and consistently control the selected application rate in gallons per square yard regardless of the forward speed of the distributor truck.

A check of distributor equipment as well as application rate accuracy and uniformity of distribution shall be made when directed by the Engineer.

Calibrate the distributor in accordance with ASTM D2995-99 in the presence of the Engineer.
