Training

Certification is the confirmation that a person has obtained the necessary knowledge of a specific pavement preservation treatment and verified by examination from a recognized independent third party specializing in the field.

What is Certification ?

Because the best designs and materials are

• f no value without quality workmanship.

Why is Certification Important ?

Causes of poor pavement performance !

Chip Seal: Poor Construction Quality

Example of Unacceptable Work

Micro Surfacing: Poor Construction Quality

Example of Unacceptable Work

Crack Treatment: Poor Construction Quality

Example of Unacceptable Work

• Certification has been in highway construction since

developed and endorsed by AASHTO in 1976. Certification is commonly required for: ─ Asphalt ─ Concrete ─ Soils

• The TSP·2 Certification Program was approved by the

AASHTO TSP·2 Oversight Panel and endorsed by the ISSA Board of Directors in 2016.

Certification Background

• In July 2018, the AASHTO Maintenance Committee (MaC)

passed a resolution encouraging states to require the certification of agency and contractor personnel involved in the design and construction of preservation treatments.

Certification Background

Certification Benefits for Agency

• Ensures that future investments in the preservation

treatment will be properly designed and constructed.

• Certified personnel will serve as the agency technical

experts for the treatment.

• Provides greater confidence that the treatment will

perform as intended.

Certification Benefits for Contractor

• Ensures that key employees possess pivotal

knowledge to construct high quality preservation treatments.

• Validates the contractor’s commitment to a

trained and qualified work force.

• Gives the contractor greater confidence that the

treatment will perform as intended.

• 1. Slurry Systems (Micro Surfacing, Slurry Seal & Polymer Modified

Slurry)

• 2. Chip Seals
• 3. Crack Treatments

Certification Examinees

In August 2018, Sealcoating, Inc., of Braintree, Massachusetts, became the first company to receive Company Certification for Slurry System Treatments.

Contractor Company Certification

The contractor must:

• Develop and submit for approval a detailed Quality

Control Plan

• List key employees that possess individual certifications
• Document that field employees engaged in constructing

the treatment participate in 4 hours of classroom training and 4 hours of in the job training (OJT) each year.

Company Certification Requirements

The quality control plan must define the expected results and describe how those results will be achieved. An acceptable quality control plan shall identify ………..
