AASHTO T 384-19 PDF Download

AASHTO T 384-19 is a standard method of test for protective sealers for Portland cement concrete. The standard provides guidelines for the selection and evaluation of sealers used to protect new concrete or extend the lifespan of existing concrete structures in highway construction. The standard is aimed at ensuring the quality and performance of sealers through testing and evaluation processes.

The standard classifies sealers into two categories: coatings and penetrants. Coatings are sealer products that remain on the surface of the concrete, while penetrants are sealer products that penetrate into the concrete without substantially altering its appearance.

Additionally, the standard references R 94, which is a guideline for quality assurance, job site quality control, and reapplication of protective sealers for Portland cement concrete. This provides further guidance on testing and evaluation of sealers for both job site quality assurance and reapplication purposes.
