摘要: Pavement preservation is recognized as a means to lower life cycle cost of road asset; but, possibly not all surface distress data are documented and kept further enhance beneficial decision for the best treatment at proper time. This paper presents study identify types treatments used in Alaska how had performed. Forty-four sections that received pavement were surveyed person along with available from Department Transportation Public Facilities (AKDOT&PF). The PASER manual asphalt roads was evaluate distresses sections. Different provided varied improvement life, which also consistent findings parallel research efforts literature survey conducted by team. In addition, failure modes different regions different. same may be applied but prevent or mitigate modes. Use some (for example, chip seals) should considered job-specifically. There need create database keep good records current future projects better evaluating applying them.
