Transportation agencies receiving federal-aid must conduct biennial Work Zone Process Reviews (WZ PRs) to analyze their current policies and procedures for managing work zone traffic operations (23 CFR 630). In an environment of constrained resources, agencies are pressed to find the time for comprehensive self-evaluation or to conduct broad review

Engagement from all stakeholders helps a STIC thrive. These dynamic partnerships rely on effective collaboration so that members of the transportation community in each State can brainstorm, exchange information, and generate new ideas that benefit their organizations and communities. Strategically aimed communication can help reach this goal.

On a monthly basis, each State is required to report to the Federal Highway Administration (FHWA), the amount of gallons taxed by that state. This data is analyzed and compiled by FHWA staff. The data on the amount of on-highway fuel use for each State is then used to attribute federal revenue to each State. Yearly, the FHWA, Office of Policy, prov

Repair and rehabilitation of the aging highway infrastructure continues to be a challenging endeavor for all U.S. highway agencies. Thousands of miles of highway pavements need rehabilitation, and many of these highways carry over 100,000 vehicles/day, including a large percentage of trucks. Extended lane closures must be avoided to prevent compoun

This Tech Brief presents an overview of permeable interlocking concrete pavement (PICP) and its use. General information is provided on PICP composition with a summary of benefits, limitations, and characteristics. Important considerations, such as hydrologic design, structural design, construction, and maintenance, are also provided.
Precast concrete pavement (PCP) technology is gaining wider acceptance in the US for rapid repair and rehabilitation of concrete pavements as well as for reconstruction of heavily trafficked asphalt concrete intersections. This TechBrief provides a summary of the technical resources available to engineers and planners seeking an understanding of PC

Electrical resistivity is a property that indicates the material’s resistance to the passage of electrical charges at a defined temperature. In concrete, resistivity is directly proportional to the resistivity of the pore solution, and inversely proportional to the volume and connectivity of the pores. Formation factor is the ratio of concrete resi

Researchers are studying how building materials can be made in a way that is less energy intensive and can result in cost savings. One such building material is concrete, which is used to make sidewalks and roads, among other structures. Concrete consists of cement, water, sand, and stones that are mixed together. When cement is mixed with water, i
