ADMINISTRATIVE RESISTANCE DECISIONS AND PROCEDURES FOR TREATMENT OF STRUCTURES

摘要

Aging resistant asphalt compositions and related methods of preparing and applying the same are provided. The aging resistant asphalt compositions can include a base asphalt with specified properties combined with an aging resistance additive, to produce modified asphalt compositions having a colloidal index within the range of about 3.7 to about 8.0, a saturates content of less than about 10% by weight, and measurable age-resistant properties. The aging resistant asphalt compositions are useable in a variety of asphalt paving and non-paving applications. The aging resistant asphalt compositions provide improved resistance to both moderate and low failure temperatures of conventional paving asphalts throughout its service life by reducing age-related failures.
