The NCHRP has released a new Subsurface Investigation Manual to update the 1988 AASHTO Manual of the same name. Imagine trying to capture every change in technology, methods, and approaches to geotechnical investigations from the past 30 years. After a very cursory review, it appears that the authors of the new manual have done just that! This is sure to be a must-have resource for every geotechnical engineer, whether they practice on the transportation side of the business or not. I’ll be looking forward to having a deeper dive into the changes to the manual. If you notice anything important, don’t be afraid to leave a comment here! You can download the NCHRP Manual on Subsurface Investigations from the Transportation Research Board (TRB).

An estimated 380,000 thousand jobs and hundreds of construction projects are in jeopardy across the nation after Congress failed this week to fix a 3.3 billion dollar deficit in the Highway Trust Fund. The House and Senate dropped a provision from a three-month aviation tax extension bill that would have provided $8 billion to keep the nationâ€™s transportation account solvent.
AASHTO Executive Director John Horsley expressed his strong disappointment saying, â€œIf members of Congress believe that this failure to act has no consequences, theyâ€™re wrong.â€ Most states depend on federal funding to support transportation projects, but states wonâ€™t know if their federal highway funding will be cut by 34 percent until their fiscal year begins. For many states, the fiscal year starts on July 1.
This failure to act sets the stage for a last minute effort in late September to rescue Americaâ€™s Transportation Account. If that does not occur, the federal-aid highway program will be reduced by $13.5 and $20 billion.
This loss would be another blow to the transportation industry, which is suffering from a stagnant economy, high fuel prices, inflationary pressures, and natural disasters.
The American Association of State Highway and Transportation Officials (AASHTO) is the â€œVoice of Transportationâ€ representing all 50 states, the District of Columbia, and Puerto Rico. AASHTO is a nonprofit, nonpartisan association serving as a catalyst for excellence in transportation.
AASHTO’s Standard Specifications for Transportation Materials and Methods of Sampling and Testing, 33rd Edition and AASHTO Provisional Standards, 2013 Edition are now available for pre-order, delivery will start later this month. The 33rd Edition of […]
I first heard about Geotech Tools through a TRB Strategic Highway Research Program (SHRP 2) publication titled Geotechnical Solutions for Soil Improvement, Rapid Embankment Construction, and Stabilization of the Pavement Working Platform. The final version of the report was released in February of this year. The report is one of the project deliverables for the SHRP 2 Project R02.
The primary deliverable of the project and the subject of this review is Geotechtools.org, a web-based tool for geotechnical engineers, structural engineers and pavement engineers. This website is a “toolkit of geotechnical information to address all phases of decision making from planning to design to construction.” What does that mean exactly? Great question. In this article I will give you an overview of the site and its resources and how it might help you on your next project.
