thoroughly blend the recycling agent and the loose mix asphalt into a homogenous mixture and uniformly redistribute the resultant rejuvenated asphalt mixture onto the mat.

1. Scarifier The scarifying unit shall contain at least 2 rows of spring-loaded tines that are adjustable to scarify up to 14 feet wide. The tines shall be arranged such that the lateral spacing between tines on immediately adjacent rows does not exceed 1 inch.

The unit shall be capable of conforming to the pavement contours to ensure a uniform penetration from the tines and prevent damage to utility structures.

2. Sprayer This unit shall be immediately behind the scarifying unit and capable of uniformly applying the recycling agent to the scarified asphalt pavement at the approved rate.

The size of the nozzles located on the spray bar and pump shall be selected based upon the rate of application and the forward speed of the heater scarification unit.

This unit shall be equipped with a mass flow meter and measuring system which is capable of maintaining the required application rate of the recycling agent within a tolerance of ± 5% of the mix design. The measuring system shall continuously verify and display the application rate of recycling agent and cumulative total with respect to the volume of scarified material.

When operating the heating unit(s), care shall be taken not to damage adjacent property and vegetation. All adjacent property and vegetation that becomes heat-damaged shall be repaired immediately, at no additional cost to the State.

The heater scarification equipment shall maintain the temperature of the scarified material, 5 feet beyond the screed, between 275˚F and 325˚F during recycling.

The speed of the equipment shall be controlled to ensure that the recycled pavement is properly milled, mixed, and uniformly distributed to the proper thickness, slope, and crown shown on the contract plans. Material placed shall be consistent and free from segregation.

The width of each pass shall be set to provide proper placement of longitudinal joints, including a 3-inch overlap onto adjacent lane passes.

The final recycled pavement shall conform to the requirements of §404-3.10, Surface Tolerance and §404-3.11, Thickness Tolerance. The depth of the loose scarified mix behind the screed unit shall be measured prior to the rolling operation. Adjust the paving equipment if the loose mix depth does not provide the compacted depth specified in the contract documents.

In areas not accessible to scarifying equipment, such as around catch basins or manholes, the Engineer shall determine any required repairs. Repair all designated areas, as approved by the Engineer, at no additional cost to the State.

A. First day Prior to the start of work, the Engineer will select two coring locations within one lane mile of each other. The Contractor shall extract two cores from each location. The Contractor shall extract asphalt binder from the surface layer of one core at each location and test it for penetration. The second core at each location shall be provided to the Engineer for companion testing by the Department. All required core and loose mix samples shall be taken at least 500 feet beyond the day’s production start location.

If approved by the Engineer, the Contractor shall take two dry loose mix samples of the scarified pavement, prior to rejuvenation, at the two core locations or as determined by the Engineer. One dry loose sample from each location shall be retained by the Contractor and one dry loose sample shall be provided to the Engineer to be tested or retained by the Department.

At each location where the two dry loose samples are taken, four rejuvenated loose samples shall be taken either behind the screed or in any place after the spraying and mixing units. These samples shall represent the day’s production. All samples shall be identified by their locations at the project site. Two of the rejuvenated loose mix samples from each location shall be tested for penetration by the Contractor. The remaining rejuvenated loose mix companion samples shall be provided to the Engineer.

Penetration test results shall be submitted to the Engineer by the end of the next day’s production. If test results are not provided, the Engineer may shut down the scarification process until the results are submitted. Penetration of the PG binder recovered from the recycled mixture shall be determined in accordance with AASHTO T 49. The average penetration value of the rejuvenated loose mix samples shall be a minimum of 30% or more of the penetration value of the samples taken from the existing pavement cores.

The Contractor shall test the dry loose mix samples for penetration when requested by the Engineer.

Failing penetration results from the rejuvenated loose mix samples shall be addressed as follows: A new application rate shall be determined and submitted to the Engineer for approval. The sampling and testing procedure in this section shall be repeated. New penetration test results shall be submitted to the Engineer by end of the next day’s production. This process shall be repeated until the average penetration value of the rejuvenated loose mix is 30% or more of the penetration value of the core samples from existing pavement.
