In general, the Contractor shall furnish and incorporate all required asphalt antistripping agents in asphalt concrete paving mixtures and asphalt-stabilized base mixtures to meet moisture resistance testing requirements.

A. Lime. The Contractor shall provide hydrated lime or commercial lime slurry in accordance with

DMS-6350.

B. Liquid Antistripping Agent. The Contractor shall provide a liquid antistripping agent that is uniform and shows no evidence of crystallization, settling, or separation; ensure that all liquid antistripping agents arrive in properly labeled and unopened containers, as shipped from the manufacturer, or sealed tank trucks with an invoice to show contents and quantities. The Contractor shall provide product information to the COR including:

USIBWC Contract No.: IBM10B0006-Amendment 5 Page 50.22.00 - 2 material safety data sheet, specific gravity of the agent at the manufacturer’s recommended addition temperature, manufacturer’s recommended dosage range, and handling and storage instructions.

2.2 EQUIPMENT

The Contractor shall provide all equipment to store, handle, dispense, meter, and mix asphalt antistripping agents.

3.1 LABORATORY DESIGN EVALUATION AND PRODUCTION MIXTURE

VERIFICATION

The Contractor shall provide a laboratory mixture design and production mixture that meets moisture resistance requirements. During design and production, evaluate proposed asphalt pavement or base mixtures according to the moisture resistance requirements in the asphalt mixture specification.

Governing specifications require the Contractor or the Government to design the mixture, and the party performing the design is responsible for the moisture susceptibility evaluation. If the Contractor designs the mixture, the Government verifies compliance. If an antistripping agent is required, determine the dosage needed to achieve the moisture resistance requirements during design. Use this addition rate in the production mixture. When using lime, add between five-tenths percent (0.5%) and two percent (2%) of hydrated lime or commercial lime slurry solids by weight of the individual aggregate treated. When using a liquid antistripping agent, add it to the binder in accordance with the manufacturer’s instructions and do not exceed the manufacturer’s maximum recommended dosage rate. If the production mixture does not meet moisture resistance requirements, stop production and correct the problem.

3.2 ADDITION OF ANTISTRIP AGENTS AT THE MIX PLANT

The Contractor shall connect the measuring device for the addition of the asphalt antistripping agent into the automatic plant controls to automatically adjust the supply to plant production and provide a consistent percentage in the mixture; set automatic plant controls so that an interruption of asphalt antistripping agent’s flow causes plant shutdown.

A. Lime. The Contractor shall incorporate lime in a manner that thoroughly and uniformly distributes lime onto the aggregate surface or into the mixture; use metering equipment, as compliance-confirmed, to ensure the required quantity of lime is used.

(1) Hydrated Lime. Add to the aggregate by one of the following methods, unless otherwise shown on the plans:

(a) Mix in a compliance-confirmed pug mill mixer with damp aggregate containing water at least two percent (2%) above saturated surface dry conditions.

(b) Add into the drum-mix plant immediately before asphalt binder addition or in the pug mill of the weigh-batch plant before asphalt binder addition. If a weigh-batch plant is used, dry mix aggregates and lime before adding asphalt binder.

USIBWC Contract No.: IBM10B0006-Amendment 5 Page 50.22.00 - 3

(2) Commercial Lime Slurry. Add to the aggregate by one of the following methods, unless otherwise shown on the plans:

(a) Mix in a suitable pug mill mixer with the aggregate.

(b) During mixture production, mix with aggregate between the plant cold feeds and the dryer or mixing drum.

B. Liquid Antistripping Agent. The Contractor shall incorporate into the binder as follows:

(1) Handle in accordance with the manufacturer’s recommendations.

(2) Add at the manufacturer’s recommended addition temperature.

(3) Add into the asphalt line by means of an in-line-metering device, and a blending device to disperse the agent.

(4) Place the metering and blending devices in a compliance-confirmed location.

The work performed by the Contractor under this specification shall not be paid for directly, but shall be considered subsidiary to the various Bid Items under this Contract

Pavement temperatures are estimated from air temperatures using an algorithm contained in a Department-supplied computer program, may be provided by the Department, or by following the procedures outlined in AASHTO MP 2 and PP 28.

2 This requirement may be waived at the Department’s discretion if the supplier warrants that the asphalt binder can be adequately pumped, mixed, and compacted at temperatures that meet all applicable safety, environmental, and constructability requirements. At test temperatures where the binder is a Newtonian fluid, any suitable standard means of viscosity measurement may be used, including capillary (T 201 or T 202) or rotational viscometry (T 316).

3 Viscosity at 135°C is an indicator of mixing and compaction temperatures that can be expected in the lab and field. High values may indicate high mixing and compaction temperatures. Additionally, significant variation can occur from batch to batch.

Contractors should be aware that variation could significantly impact their mixing and compaction operations. Contractors are therefore responsible for addressing any constructability issues that may arise.

4 For quality control of unmodified asphalt binder production, measurement of the viscosity of the original asphalt binder may be substituted for dynamic shear measurements of G*/sin(�) at test temperatures where the asphalt is a Newtonian fluid. Any suitable standard means of viscosity measurement may be used, including capillary (T 201 or T 202) or rotational viscometry (T 316).

5 Silicone beam molds, as described in AASHTO TP 1-93, are acceptable for use.

USIBWC Contract No.: IBM10B0006-Amendment 5 Page 50.24.00 - 19

6 If creep stiffness is below 300 MPa, direct tension test is not required. If creep stiffness is between 300 and 600 MPa, the direct tension failure strain requirement can be used instead of the creep stiffness requirement. The m-value requirement must be satisfied in both cases.
