Pedestrian-induced vibrations on structural systems
(Texas A&M University, 1996)
Although models have been suggested to describe the loadings caused by pedestrian motion, they do not adequately model pedestrian loading patterns. Therefore the task of describing pedestrian motion was approached from a ...
Evaluation of alternative sign replacement strategies
(Texas A&M University, 1996)
The Secretary of Transportation was directed by Congress, in the U.S. DOT Appropriations Act of 1992, to revise the manuel on Uniform traffic Control Devices (MUTCD) to include a standard for a minimum level of retroreflectivity ...
Sulfate induced heave in lime stabilized soil
(Texas A&M University, 1994)
The addition of hydrated lime to clay soils is one of the most common methods of soil stabilization. However, when sulfates are present in the soil, the calcium in the lime reacts with the sulfates to form ettringite, an ...
Safety effects of barrier curb on high-speed suburban multilane highways
(Texas A&M University, 1994)

An evaluation of the flexible pavement design system FPS19
(Texas A&M University, 1998)
The flexible pavement design program used by the Texas Department of Transportation (TXDOT) for the past 20 years, FPS1 1 , uses the Stiffness Coefficient, based on Dynaflect deflections, to characterize pavement strength. ...
An evaluation of inductance loop detector lead length and optimal speed trap distance
(Texas A&M University, 1994)
Reducing congestion in our nation's urban areas has become a top priority of state departments of transportation nationwide. The development and construction of freeway management systems have recently begun to help reduce ...
Development of an electrical resistivity cone for the detection of gas hydrates in marine sediments
(Texas A&M University, 1994)
Natural gas hydrates are formed when, under certain pressure and temperature conditions, gas molecules become encaged by hydrogenbonded oxygen atoms, forming a solid, ice-like crystalline substance. They have been found ...
A framework for a coarse aggregate classification system
(Texas A&M University, 1994)
Coarse aggregates are the major constituents of concrete or asphalt mixtures and are widely used in various construction purposes. A classification system for these aggregates would provide a systematic means of aggregate ...
An evaluation of pavement markings and raised pavement markers at left exit lane drops
(Texas A&M University, 1994)
Most highway engineers agree that freeway exit lane drops create problems in terms of safety and efficiency. A driver can create a hazardous situation when making a sudden lane change out of or into an exit-only lane. Since ...
