Historically, the Maryland State Highway Administration (MDSHA) has relied almost exclusively upon rehabilitation strategies to maintain their pavement system. While rehabilitation is a valid strategy, it is not necessarily the most cost-effective strategy; quite often, the more cost-effective treatments to maintain the pavement system are pavement preservation and preventive maintenance treatments. However, there was virtually no documentation available within MDSHA on these. Now, pavement preservation is an important facet of maintaining MDSHA’s roadways.
The MDSHA has now issued a document is to provide general guidance on the selection of pavement preservation and maintenance treatments. The guide is intended to be used by MDSHA pavement and geotechnical engineers and by District personnel (Project Development Teams, Maintenance and Construction Sections). The Guide is available for downloading.
