HMA Crack Sealers (CS)

AASHTO is pleased to announce launch of a coordinated evaluation of Crack Sealers for HMA pavements under the auspices of its National Transportation Product Evaluation Program (NTPEP).

Crack Sealers are commonly used to protect and seal Hot Mix Asphalt (HMA) pavement cracks from moisture and other deleterious material. Under this NTPEP evaluation program the sealers are field tested for three years and laboratory tested according to a variety of ASTM specified test methods.

The NTPEP Technical Committee responsible for authoring the Project Work Plan convenes yearly at the NTPEP National (Annual) Meeting. During this working meeting, the Project Work Plan is discussed, changes made, and shortly thereafter balloted for adoption. Improvements are immediately implemented in the next available testing cycle. When compared to other standards development exercises, the NTPEP process is agile, effective and efficient.
