Investigating Paleoenvironmental and Diagenetic Controls on the Skid Resistance of Carbonate Construction Aggregates Mined from the Lower Cambrian Kinzers Formation in the West York 7.5-minute Quadrangle, PA
Presented by: Seth Pelepko, P.G. – PA DEP
Abstract: Wet pavement friction, or skid resistance, is one of the most important engineering considerations in highway design from a safety standpoint. For bituminous pavements, skid-resistance performance is primarily a function of the durability, texture, and composition of coarse aggregate used to construct the wearing course, or the uppermost layer of the road surface. Cambrian age carbonate construction aggregates mined in Pennsylvania - although relatively simple mineralogically - exhibit a wide variety of textures that developed in response to complex paleoenvironmental and diagenetic processes. To reveal what factors influence the petrographic properties of such aggregates and relate these attributes to skid resistance, carbonate construction aggregates currently being mined from the Lower Cambrian Kinzers Formation in the West York 7.5-minute quadrangle, Pennsylvania have been sampled and subjected to laboratory testing.
Speaker Bio: Seth Pelepko is the Well Plugging and Subsurface Activities Division Manager for the PA DEP’s Bureau of Oil and Gas Planning and Program Management. He has worked in this capacity for two years and has been with the Oil and Gas Program for over six years. His areas of interest include stray gas migration case work, gas well integrity, and legacy well issues. He previously worked as a petrographer responsible for evaluating construction aggregate and engineering structures and as a hydrogeologist for both the Commonwealth of PA and for a private consulting firm. He received a BS degree in Earth Sciences in 1998 from the Pennsylvania State University and MS degree in Geology from the University of Delaware.
