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 ...
Modeling heat transfer in mass concrete floors with radiant heat from ground source systems
(2017-05)
Thermal properties of concrete have been extensively studied for the design of mass concrete structures regarding cracking and stress development considerations. The rise in blended cement with limestone and fly ash as a ...
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 ...
Exploring pavement texture and surface skid resistance using soft computing techniques
(2017-12)
Pavement skid resistance and texture characteristics are important aspects of road safety. Traditional pavement friction measurement from limited contact with pavement is influenced by multiple factors such as temperature, ...
Development of predictive modeling tools for estimating fuel use and emission rates for heavy-duty diesel construction equipment
(2014-05)
Heavy-duty diesel (HDD) construction equipment consumes a substantial amount of fuels and consequently emits a substantial amount of pollutants into the environment. This dissertation presents methodologies for estimating ...
Development of a productivity-based economic, energy, environmental model for heavy duty diesel construction equipment
(2013-05)
The use of heavy duty diesel (HDD) equipment in infrastructure projects accounts for a large quantity of fuel consumption, pollutants emissions and the majority of the total cost of the project compared to others. Construction ...
Development of precast, prestressed concrete pavement technology
(2013-12)
Precast prestressed concrete pavement (PPCP) can provide many advantages over other pavement alternatives whether asphalt or concrete. The possible advantages are thinner pavement, faster construction, increased durability, ...
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 ...
