AASHTO T 367-17 PDF Download

AASHTO T 367-17 is a standard method of test that specifically focuses on the accelerated aging of bituminous sealants and fillers using a vacuum oven. This standard is applicable to the crack sealants and fillers that are commonly used in the construction and maintenance of roadways. The purpose of this standard is to simulate the aging process that these materials may undergo during their service life, in order to determine their long-term performance and durability.

The test procedure outlined in AASHTO T 367-17 involves subjecting the bituminous sealants and fillers to high temperatures and reduced pressure conditions inside a vacuum oven. The samples are placed in the oven and are heated under controlled conditions for a specified duration. This accelerated aging process aims to replicate the effects of long-term exposure to environmental factors, such as heat and air, on the bituminous materials.

By subjecting the sealants and fillers to accelerated aging conditions, this standard allows for an assessment of their performance characteristics, such as changes in viscosity, hardness, adhesion, and flexibility. The results obtained from this test method can provide valuable information for determining the suitability of these materials for use in road construction and maintenance projects, as well as for evaluating their expected service life and the need for potential adjustments in their formulation or application procedures.
