Abstract

This study investigated the benefits and costs of commonly used thin surface treatments for maintenance of bituminous pavements in Kansas. Cost andperformance data was collected from the Kansas Pavement Management Information System (PMIS) for all treatments applied from 1992 to 2006. The results show that seal coats have a very short average service life on interstate highways. The average life on non-interstate highways is about four year. However, this life is slightly lower than other thin surface treatments including hot-mix asphalt (HMA) overlays. Seal coats also have a significantly lower equivalent uniform annual cost (EUAC) than all other thin surface treatments in Kansas. A comparison of pavement benefit values beforeand after application showed that seal coat could not mitigate distressesbetter than other methods, especially thin HMA overlays. However, its performance is very close to that of the slurry seal.
