RAP: The State of the Practice

Everything old is new again as State transportation departments look at increasing their use of reclaimed asphalt pavement (RAP), optimizing the use of natural resources while saving money. A new report from the Federal Highway Administration (FHWA), Reclaimed Asphalt Pavement in Asphalt Mixtures: State of the Practice (Pub. No. FHWA-HRT-11-021), highlights RAP use across the United States, as well as best practices for increasing the percentage of RAP used in hot-mix asphalt (HMA) pavements while maintaining high-quality infrastructure.

FHWA Offers New Guidance on Hollow Bar Soil Nails

Guidance for mitigating corrosion in hollow bar soil nails is presented in a new Federal Highway Administration (FHWA) report, Hollow Bar Soil Nails: Review of Corrosion Factors and Mitigation Practice (Pub. No. FHWA-CFL/TD-10-002).

Intelligent Compaction: One Giant Step Forward in Quality Control

Take a giant step forward in quality control (QC) for paving projects with the use of intelligent compaction (IC). With transportation agencies nationwide sharing the goal of producing quality projects that meet the public’s expectations for performance, high quality compaction of the pavement subgrade and materials is key to long-life performance of the roadway. In the past, a lack of technology made it difficult to perform QC and evaluate compaction operations. The quality of the compaction operation could only be assessed after completion by looking at whether the results complied with the specifications for the project. “Today, IC can provide better control and oversight of the compaction process, resulting in improved and more uniform compaction and increased productivity,” said Lee Gallivan of the Federal Highway Administration (FHWA).

FOCUS on Training—Pipe Installation, Inspection, and Quality: What You Need to Know

Find out what you need to know and look for when installing and inspecting pipes on highway construction projects with the Federal Highway Administration’s (FHWA) free Web-based course, TCCC Pipe Installation, Inspection, and Quality (Course No. FHWA-NHI-134105). Developed by the Transportation Curriculum Coordination Council (TCCC) in partnership with State transportation agency personnel, the course is available through FHWA’s National Highway Institute (NHI).

Annual Report Provides a Snapshot of NHI

Learn more about the work of the Federal Highway Administration’s (FHWA) National Highway Institute (NHI) with its new 2010 annual report. The National Highway Institute Year End Report: Fiscal Year 2010 opens with a look at the history of NHI, from its commissioning by Congress in 1970 to develop and deliver high-quality training for the transportation workforce to its ongoing innovations in training today. NHI now offers more than 300 courses across 15 program areas.
