1 Background Pavement preservation provides a means for maintaining and improving the functional con dition of an existing pavement segment through application of a preventative and responsive set of treatments that slow deterioration or correct isolated defects and thus defers costly pavement rehabilitation or reconstruction to a later time. While preservation is not expected to increase struc tural capacity of the pavement, it can lead to improved performance (e.g., slow cracking, reduce weathering, and attenuate degradation)

2 Quantifying the Effects of Preservation Treatments on Pavement Performance • Preservation has not always been included as part of the pavement management systems used by highway agencies (also referred to simply as agencies) and it has not always been possible to distinguish between pavements that have and have not received preservation treatments.
