Preventive maintenance has the potential to improve network condition by retarding future pavement deterioration. This report outlines guidelines for implementing a preventive maintenance policy for bituminous pavements. Preventive maintenance treatments currently being used in Virginia include chip seal, slurry seal, microsurfacing, and thin hot mix asphalt overlays. Historical pavement condition data were obtained from the Virginia Department of Transportations Pavement Management System for these treatments, and treatment performance models were developed. A district-level treatment selection tool was developed to facilitate the district-level decision-making process. A prioritized list of pavement sections was generated, maximizing the cost-effectiveness of the selected treatments subject to budgetary constraints set by the Central Office. As a pilot implementation, the treatment selection tool was then run for each pavement classification in each district. The results of this pilot suggest that this selection tool has the potential to be a practical decision support tool.

An increasing number of agencies, academic institutes, and governmental and industrial bodies are embracing the principles of sustainability in managing their activities. Life Cycle Assessment (LCA) is an approach developed to provide decision support regarding the environmental impact of industrial processes and products. LCA is a field with ongoing research, development and improvement and is being implemented world-wide, particularly in the areas of pavement, roadways and bridges. Pavement, Roadway, and Bridge Life Cycle Assessment 2020 contains the contributions to the International Symposium on Pavement, Roadway, and Bridge Life Cycle Assessment 2020 (Davis, CA, USA, June 3-6, 2020) covering research and practical issues related to pavement, roadway and bridge LCA, including data and tools, asset management, environmental product declarations, procurement, planning, vehicle interaction, and impact of materials, structure, and construction. Pavement, Roadway, and Bridge Life Cycle Assessment 2020 will be of interest to researchers, professionals, and policymakers in academia, industry, and government who are interested in the sustainability of pavements, roadways and bridges.

This synthesis will be of interest to highway agency executive management including administrative, budget, and finance personnel; pavement design, construction, and maintenance engineers; and maintenance operations personnel, including supervisors and maintenance crew leaders. This synthesis describes the state of the practice with respect to setting a coherent strategy of cost-effective preventive maintenance for extending pavement life. This report of the Transportation Research Board describes the practices of state, local, and provincial transportation agencies that are attempting to minimize the life-cycle costs of pavements and are identifying, during the design of the pavement rehabilitation, reconstruction, or construction projects, the future preventive maintenance treatments and the timing and funding for those treatments. It includes a review of domestic literature and a survey of current practices in North America. The appendices include a primer on pavement design and construction, the benefits of preventive maintenance of pavements, a summary of the questionnaire data collected, a simulation of pavement management strategies, and an example process to demonstrate the cost- effectiveness of preventive maintenance.

An extensive literature review was conducted to synthesize past and ongoing research related to highway pavement maintenance and preservation techniques. The literature review was augmented with a web-based email survey that was distributed to all 50 U.S. states, the District of Columbia and 11 Canadian provinces, for a total of 62 recipients. The literature review and survey results provide interesting qualitative overviews of the state-of-the-practice of preventive maintenance treatments, and how these treatments are instigated, managed, and accessed by transportation department personnel throughout North America. This report focuses on studies that quantified the performance of various preventive maintenance treatments, including the effect these treatments have on pavement performance.

Typical maintenance activities by the Virginia Department of Transportation (VDOT) for existing asphalt pavements involving a periodic placement of a 1.5-in to 2-in layer of asphalt concrete are becoming increasingly costly. When applied at the right time, pavement preservation treatments can restore a smooth, safe driving surface while saving money on future rehabilitation costs. The purpose of this study was to evaluate the performance of three preventive maintenance treatments applied to US 301 in Sussex County, Virginia, to extend pavement life. This report documents the installation of a cape seal application of FiberMat (i.e., FiberMat with microsurfacing on top) over an existing asphalt pavement. FiberMat is designed to act as a crack-resistant membrane and incorporates two applications of polymer-modified asphalt emulsion with a layer of fiberglass strands between them. The study also included a performance comparison with more conventional VDOT surface treatment options: regular cape seal (chip seal with microsurfacing), and microsurfacing without a chip seal. Three years after the treatment application, a visual survey complemented by automated distress data from VDOT’s Pavement Management System showed that the section with FiberMat and microsurfacing performed well with very little reflective cracking. The chip seal with microsurfacing (i.e., regular cape seal) also performed well, but reflective cracking was higher compared to the fiber-reinforced section. The control section (microsurfacing only) showed extensive cracking after 3 years. This study showed that pavement preservation activities such as the use of fiber-reinforced chip seal with microsurfacing and modified single seal with microsurfacing improved both the pavement condition and the surface characteristics in a very cost-effective manner. Based on this study, the unit cost of fiber-reinforced cape seal was 5 .95 dollars/yd2 and that of conventional cape seal was 3 .99 dollars/yd2. In comparison, the average cost of a 2-in mill and fill corrective maintenance treatment with a conventional asphalt plant mixture in VDOT’s Hampton Roads District was 1 0.35 dollars/yd2.
