This study evaluated 6 specific preventive treatments. Four treatments are for asphalt concrete surfaced (flexible) pavements: chip seals; crack sealing; slurry seals; and thin overlays. Two treatments are for portland cement concrete surfaced pavements: joint and crack sealing; and undersealing. Performance of the pavement sections with the treatments was compared with the performance of a similar pavement section without the treatment. Performance is measured in terms of pavement distress, roughness profile, surface friction, and structural capacity. All of the flexible pavement test sections and most of the rigid pavement test sections have been constructed. Performance data are being collected. This report discusses the experimental design, project selection, construction, data collection, analysis, and future activities of the pavement maintenance effectiveness project.

Established as part of the Strategic Highway Research Program (SHRP) and now managed by the Federal Highway Administration (FHWA), the Long Term Pavement Performance (LTPP) program faces a significant challenge. Over the past decade, the LTPP program has developed a solid knowledge base for understanding how pavements perform. Its challenge throughout its second decade is to build on this foundation--to further the understanding of why pavements perform as they do. To address this challenge, FHWA has initiated several efforts that require the support and active participation of the States and Provinces. The intent of this document is to describe the challenge the LTPP program faces and explain the efforts underway to address this challenge. This document is presented in the following sections: Introduction; The Challenge; Addressing the Challenge; Critical Issues; and Future Opportunities.

Project 0-4517 was established to summarize the results from the Lufkin experiment on US 59 and to develop statewide guidelines on how to select rehabilitation strategies for jointed concrete pavements (JCP). This year 1 report reviews the performance of the six experimental sections on US 59 and makes recommendations for statewide implementation. The best performing section in Lufkin was the flexible base overlay, which involved placing high-quality crushed limestone directly over the JCP followed by an underseal and thin asphalt overlay. This was also one of the least expensive treatments used in the experiment. The large stone mix also gave good performance, but the crack and seat and full-depth repair techniques did not perform well. A forensic investigation was conducted to attempt to explain the variation in treatment performance. To complement the Lufkin results, a review is also presented of the performance of other JCP rehabilitation techniques recently evaluated by TxDOT districts. An evaluation of crack retarding asphalt layers (Strata(R)), grid layers (GlasGrid(R)) and slab fracturing techniques is also included in the report.

This research is being conducted to evaluate the performance of various pavement preservation treatments over time and under different environmental conditions to quantify the economics of each treatment type. There are three primary techniques utilized in Colorado for preservation of asphalt pavements and three for concrete pavements.

The performance of CRCP has revealed a number of failure modes that are traceable to design, construction, materials, and maintenance deficiencies and such other factors as environemntal conditions and traffic loadings. This report of the Transportation Research Board includes a review of the cumulative experiences of state that have constructed and maintained CRCP. Guidelines for repair techniques are included, and areas of needed research are identified.

The state of the art of Portland cement concrete pavement evaluation is reviewed with emphasis on the methods applicable to the urban freeway environment. Methods are recommended for texture evaluation, void detection and condition surveys. Data analysis methods useful for the development of pavement performance models are presented. The overall framework for life cycle cost (LCC) analysis is described with recommendations for the development of a LCC method for the Arizona Department of Transportation.
