Open Access Theses & Dissertations
This research develops a methodology to quantify the impact of asphalt pavement conditions on vehicular gas emissions based on statistical analysis to correlate the relationship between asphalt pavement roughness and gas emissions. ANOVA (Analysis of Variance) hypoThesis tests were used to compare the factors affecting the results. The roughness was measured with the International Roughness Index (IRI) using a profilometer provided by TxDOT and the gas emissions were measured with a Portable Emission Measurement System (PEMS).
This research also presents the savings obtained in gas emissions using different maintenance and rehabilitation strategies established by TxDOT (Preventive Maintenance, Light Rehabilitation, Medium …
