Professional Biography
Justin Roth has over 10 years of professional experience as a petrologist/petrographer, stemming from his more than a decade-long relationship with the petrographic microscope. As a Materials Scientist, Justin characterizes concrete samples based on aggregate composition, cement paste quality, water/cement ratio, air void percentage, depth of carbonation, and evidence of alkali-silica reactions (ASR). Through these investigations, Justin provides insight into concrete’s big-picture ideas: potential failure mechanisms, corrosion, weathering/leaching, fire damage, sulfate attack, and freeze/thaw durability.
Spending the first part of his career as a petrologist in the oil and gas industry, Justin achieved expertise in various methods of characterizing rock types based on composition, texture, organic content, porosity, and permeability.
