Paint Pavement Marking Performance Prediction Model That Includes The Impacts Of Snow Removal Operations, Dale M. Mull
Paint Pavement Marking Performance Prediction Model That Includes The Impacts Of Snow Removal Operations, Dale M. Mull
Theses and Dissertations
The results of this research effort were captured in two manuscripts drafted for publication in peer reviewed journals. The first manuscript validated a previously published model with an expanded data set, updated service life predictions for painted pavement markings using recently released pavement marking retroreflectivity minimums, and incorporated recent cost data to evaluate two alternative methods of compliance with the new retroreflectivity minimums for two-lane roads. The second manuscript developed a new performance prediction model for paint pavement markings that includes the impact of snow removal operations and then applied the model to four real-world roadways to determine if replacement …
Impact Of Snow Removal Operations On Thermoplastic Pavement Markings, Monica L. Monfette
Impact Of Snow Removal Operations On Thermoplastic Pavement Markings, Monica L. Monfette
Theses and Dissertations
This pilot study explored the effect snow removal operations have on thermoplastic pavement markings. Including snow removal as a separate independent variable is unique because much of the previous research performed on pavement marking degradation mentioned snow removal as a direct cause in a marking degrading more rapidly; however, it is mentioned as an afterthought and a suggestion to be considered in future research. This pilot study looked at 10 thermoplastic markings and all marking data were collected in the field, using a hand-held retroreflectometer. Data collected began 60 days after initial marking application and ended 12 months after initial …
The Effect Of Loose Mix Aging On The Performance Properties Of Warm Asphalts, Thomas Martin Clements
The Effect Of Loose Mix Aging On The Performance Properties Of Warm Asphalts, Thomas Martin Clements
University of Kentucky Master's Theses
Recent improvements in warm mix asphalt technologies have spurred an aggressive adoption of these new practices within the asphalt paving industry. Concerns have arisen among federal and state agencies about the effects of this line of products on the performance of asphalt pavements. An investigation of the effects of lowering mixing, aging and compactions temperatures while varying the loose mix aging time was performed. Hamburg Wheel Tracking, Flow Number, Dynamic Modulus and Fracture Energy testing were used to evaluate mechanistic properties of the materials.
