Risky Business: Identifying an Acceptable Rockfall Standard
For many parts of the U.S. highway system, cut slopes in rock are as common as bridges and embankments. These cut slopes, as well as some natural ones, produce rockfalls that pose risks to highway conditions...

Introduction
Many institutions and private industry organizations have prepared guidance documents with the latest scientific and engineering information on proper design, installation, maintenance,...

Design Considerations Common To All Permeable Pavements
Impervious cover in watersheds without controls result in increased stormwater runoff and decreased groundwater recharge in response to rainfall events. This increased runoff can be the...

Permeable Interlocking Concrete Pavement (PICP)
Permeable interlocking concrete pavement (PICP) consists of (impervious) manufactured concrete units that form permeable voids and joints, when assembled into a laying pattern. The openings...

Alternative Technologies
In recent years, new permeable pavement product variations have entered the market. This chapter describes general characteristics for several emerging products. The following types of...

Achieving Success and Avoiding Failures with Permeable Pavements
This chapter provides experienced-based recommendations on how to achieve success with permeable pavements. This information is based on an informational survey completed by designers,...

Maintenance
While site selection and proper construction are the most critical factors in establishing that permeable pavements function as designed, all must be inspected and maintained to maximize...

Hydrologic and Hydraulic Design Methods
Computational methods for hydrologic analysis, hydraulic functions, and treatment capacity of permeable pavements vary depending on the complexity of the design and level of detail in...

Permeable Pavement Research Needs
The implementation of permeable pavement installations and practices are expanding and becoming more commonplace. With this increased usage comes expanded and improved information on design,...

Microtunneling Operation
The shaft should provide safe working conditions and fully support the ground. Jacking and receiving shaft support system and sizes are typically determined by the contractor. See Chapter...

The Soil-Rock Boundary: What Is It and Where Is It?

Estimation of Curve Numbers for Concrete and Asphalt
All impervious surfaces are assigned a Curve Number (CN) of 98. However, no field or experimental evidence exists (to our knowledge) that shows why the impervious CN was assigned a value...

The Need for Geotechnical Investigation
Knowledge of the subsurface conditions is needed to decide which type of foundation to use. In the discontinuous permafrost zone, some generalizations may be made about the location of...

A Dynamic Climate Downscaling Prediction System for N.E. Brazil
The International Research Institute for climate prediction (IRI) is collaborating with several levels of government and various local and foreign researchers in several key disciplines...

How Should the U.S. and Mexico Manage Their Transboundary Water Quality?
The purpose of this workshop is to discuss with ASCE members the progress in developing a Standards document and Management Plan document associated with water quality management across...

The Big Dig's Big Dig
Widely recognized as the most demanding component of Boston's Central Artery/Tunnel Project, the tunnel jacking work performed beneath operating rail tracks represents a quantum...

Reconstructing a Grand Boulevard
Wacker Drive, the two-level riverfront roadway that has defined the boundary of Chicago's business and cultural district for more than 75 years, is undergoing a much-needed...

Single-Shell Permanent Lining: Reflections from the Structural Point of View

Effectiveness of Preventative Maintenance Strategies for AC Pavements Based on LTPP Distress Data

International Boundary and Water Commission, United States and Mexico, United States Section
