Pothole Practices Guidebook: Proactive Prevention and Patching


Book Description

Even with best practices and standards, asphalt pavements will inevitably deteriorate due to traffic, environmental effects, and aging of materials. Preserving and extending their useful life requires a comprehensive preventive maintenance program and timely, effective, and efficient repairs. This easy-to-use guidebook provides an overview of how potholes form, pothole repair methods and materials, and preventive measures.







Asphalt in Pavement Preservation and Maintenance


Book Description

This updated manual provides practical information on methods, equipment, and terminology applying to the use of asphalt in maintenance of all types of pavement structures. Topics addressed include pavement management systems, types of maintenance, rehabilitation treatments, analysis systems, pavement evaluation, distresses, materials, crack sealing/filling, patching, surface treatments, and asphalt maintenance of PCC pavements










Gravel Roads


Book Description

The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

Asset Management Implementation Plan and Tiered System Process


Book Description

This study has developed a five-year transportation asset management plan for the Colorado Department of Transportation (CDOT). This study has also developed a proposed tiering structure of the state highway system to support asset management. Asset management represents a strategic approach to managing transportation infrastructure. It embodies a set of principles to improve how an agency conducts business, how it reaches decisions, and how it processes, uses, and communicates information. CDOT, in consultation with the Colorado Transportation Commission, has already taken a number of steps toward improved asset management. A unique Investment Category approach organizes program investments within a policy-oriented framework incorporating explicit measures of performance. Other steps taken by CDOT include updates of the statewide planning process and the program prioritization process, establishment of maintenance program levels of service, institution of customer surveys, and updates of relevant information technology applications. The recommended transportation asset management plan builds upon these established concepts, methods, information, and tools to propose specific actions over the next five years in the following areas: (1) completion of all elements of the Investment Category structure; (2) incorporation of asset management principles in CDOT's planning and programming processes, building on a tiered structuring of CDOT assets that has also been recommended in this study; (3) integration of asset management information on a GIS platform, and renewal of Information Technology strategic planning to support asset management department-wide; and (4) strengthening of program delivery mechanisms and measures. The recommended tiering of the state highway system is built around the concept of interregional corridors, because CDOT is the sole provider of significant interregional highway transportation.
