Louisiana constructed two hot mix recycling projects in 1978 in order to determine the feasibility of this technology with respect to design and construction. In 1980-81 four recycled projects were constructed to examine the variations found in recycled asphaltic concrete mixtures based upon plant quality control data and verification testing. This

An investigation into a recycled asphalt pavement built in 1989 on US212 between La Plante and the Missouri River which had prematurely failed revealed an unusually high concentration of metals in the asphalt cement. These metals, capable of promoting the oxidation of asphalt, could not be attributed entirely to either the fines or the stones in th

This report describes research performed by the South Dakota Department of Transportation to investigate the problem of dowel bar misalignment in PCC pavements. Over 400 dowel bars from three (3) construction projects were inspected and compared to the dowel bar alignment specifications. This study found that the dowel bars tended to conform to the

This advisory circular provides guidance for all pilots, especially student pilots, flight instructors, and pilot examiners, on the recommended procedure to use for the positive exchange of flight controls between pilots when operating an aircraft.
Concrete cylinder and cube specimens for compression testing were compared through a survey of past research, including testing procedures, factors affecting the cylinder/cube strength ratio, and conversion factors and equations. The main difference between cylinder and cube testing procedures is capping. Cylinder ends are usually not plane or para

The Washington state transportation system is under pressure, physically and financially. Railroad abandonment, waterway drawdown and road deterioration all contribute to a sense of urgency in detailing the needs of that system. The overall purpose of this study is to provide a detailed assessment of needs, specifically for the road system in easte

This Innovations Deserving Exploratory Analysis (IDEA) project investigated two concepts for low-cost automated systems that can sense when a vehicle drifts out of its lane and then alert the driver. One system was based on vehicle-mounted infrared (IR) sensors and the other on radio-frequency (RF) sensors, both of which can detect reflective paint

This order prescribes the responsibilities and procedures for Federal Aviation Administration (FAA) aircraft certification personnel responsible for the certification process required by the Federal Aviation Regulations for civil aircraft,aircraft engines, and propellers.
The use of large trucks has steadily increased since the passage of the Surface Transportation Assistance Act to the point where they now account for over 50% of vehicle traffic on some highways in Virginia. This study identified the causal factors and predominant types of large-truck crashes on two-lane secondary roads in Virginia and compared the
