Use of smartphones to measure pavement roughness across multiple vehicle types at different speeds
Measuring pavement roughness has been an important practice for transportation agencies for many years now. Commonly, this measurement is recorded as International Roughness Index (IRI) and is collected via a data collection vehicle (DCV) using a combination of lasers, accelerometers, and a …

Development of a smartphone application to measure pavement roughness and to identify surface irregularities
Pavement roughness is an expression of the unevenness or disturbance in a pavement surface that adversely affects the ride quality of a vehicle. Roughness also affects user delay costs, fuel consumption, tire, and maintenance costs. Roughness is predominantly characterized in terms of International …

Development of models for optimal road maintenance fund allocation : A case of Ghana
… of attributes including road length, traffic, pavement roughness and percentage of work achievement. The concept of efficiency frontier was used to sub divide the proportion of funds allocated by road type into economic efficiency and equity components based on the Net Present Value/Capital, …

Machine-Learning based tool to predict Tire Noise using both Tire and Pavement Parameters
Tire-Pavement Interaction Noise (TPIN) becomes the main noise source contributor for passenger vehicles traveling at speeds above 40 kph. Therefore, it represents one of the main contributors to noise environmental pollution in residential areas nearby highways. TPIN has been subject of exhaustive …

Uncertainty quantification for pavement life-cycle stages
… rolling resistance (RR), a major component of pavement LCA use stage, has significant impact on transportation-related energy consumption. Pavement related RR mainly includes pavement structure, surface roughness (or smoothness) and texture. This research aims at addressing current challenges …

Development of mechanistic rolling resistance model for pavement life cycle assessment
… It has been shown that a major component of pavement LCA results from rolling resistance (RR) between vehicle-pavement interaction. This study focuses primarily on the development of mechanistic RR model to capture the impact of excess fuel consumption (EFC) and dynamic wheel load (DWL) …

Cracking and Roughness of Asphalt Pavements Constructed Using Cement-Treated Base Materials
… surfaces. Cracking may then cause increased pavement roughness and lead to poor ride quality. The overall purpose of this research was to utilize data collected through the Long-Term Pavement Performance (LTPP) program to investigate the use and classification of CTB layers and evaluate the …

City-scale eco-routing and pavement eco-maintenance scheduling for CO2 mitigation
… asset management perspective, a city-scale pavement degradation model is built and utilised in testing pavement maintenance scenarios. San Francisco is chosen as the case study area due to the availability of various traffic mobility and infrastructure condition data. In Chapter 3 of the …
