5 Implementation of Guidelines Implementation and use of the preservation guidelines by highway agencies will certainly involve working through a variety of institutional and external issues. Several key implementation bar- riers, such as resistance to allowing the use of lower-volume preservation treatments on higher- volume roads and the ability to convince the traveling public of the benefits and importance of preserving high-traffic-volume roads, were also formulated and presented in this report. Conclusions Several major conclusions were developed in this study. The most notable conclusions are the following: Several preservation treatments are currently being extensively used or have been documented as successfully used on high-traffic-volume roadways. Successful selection of projects and preservation treatments for high-traffic-volume roadways requires that Treatment functions be properly matched to pavement conditions; Potential effects of traffic level and climatic conditions on expected treatment performance be properly assessed; Project construction constraints be carefully examined in relation to the limitations of the treatments; and Treatment cost-effectiveness and other factors be properly and methodically considered. Recommendations Key recommendations from this study include the following: Develop a more comprehensive treatmentpavement condition matching matrix; Improve estimates of treatment performance and unit costs; and Investigate more thoroughly the impact of pavement condition, traffic level, and climatic con- dition on treatment performance.
