Pavement hydroplaning risk evaluation with Inertial Measurement Unit (IMU) and 1mm 3D texture data
(2015-07)
During wet weather automobiles traveling on pavements may experience hydroplaning that would cause out-of-control accidents. Annually 14% of all accidents with fatalities occur on wet pavements. However, not many studies ...
Novel system of pavement cracking detection algorithms using 1mm 3D surface data
(2015-12)
Pavement cracking is one of the major concerns for pavement design and management. There have been rapid developments of automated pavement cracking detection in recent years. However, none of them has been widely accepted ...
Pavement safety evaluation with 1mm 3D laser texture data
(2015-07)
Pavement safety is highly associated with surface texture characteristics. Measurements of surface texture can be conducted in either stationary or high-speed way. Texture data collected from the existing systems are ...
Characterization of pollutant emissions and fuel use for CNG transit buses
(2015-05)
Transit agencies have historically relied on diesel buses to move their passengers; however, many agencies have adopted alternative fuels such as compressed natural gas (CNG). New knowledge is needed to accurately assess ...
Aggregate proportioning for slip formed pavements and flowable concrete
(2015-07)
This is an investigation into developing a relationship between aggregate proportioning and the workability of concrete for slip formed pavements and flowable concrete applications. Workability tests were developed for ...
Direct three dimensional observation of the microstructure and chemistry of C3S hydration
(2015-12)
Although portland cement has been used for over a hundred years as the binder in concrete, the basic mechanism of hydration is still not well understood. Progress has been halted for the fact that it is challenging for ...
Development of a new tensile stress model for expansive soils
(2015-12)
The problems associated with drying shrinkage are worldwide, and cause great damage to highways and buildings constructed on expansive soils. Literature review indicates that the development of shrinkage crack is governed ...
