Methods and compositions to increase performance of asphalt cement concrete comprising recycled asphalt pavement

Embodiments of the invention are amendments to hot-mix asphalt (“HMA”) which open new price/performance areas to asphalt cement concrete (“ACC”) pavement. Equivalent-performing pavement may be made at lower cost, or higher-performing pavement may be made at equivalent-to-prior-art cost. The amendments, recycled asphalt pavement (“RAP”, and including recycled asphalt shingles [“RAS”]), and reinforcing fiber (aramid fiber) may be adjusted as described herein to achieve a desired price/performance target.

Erosion resistant composition and method of making same
11420104 · 2022-08-23 · ·

An erosion resistant composition includes a granular material and a wax including oil in which a weight percent of the oil in the wax is between 0.01-15%. The granular material includes a sand and has a first resistance to flow prior to being coated with the wax. The wax at least partially coats a portion of the granular material to form the erosion resistant composition which has a second resistance to flow after coating that is greater than the first resistance to flow prior to coating. The erosion resistant composition may be used, for example, in golf course bunkers or other landscaping applications. Related methods of making the erosion resistant composition are also described in which the granular material is dried, the wax is heated, and the granular material is blended with the melted wax.

Controlled hydration of quicklime

The present invention provides a liquid composition of quicklime particles within an alkylene glycol-based paste or slurry environment, which allows for pumpability and meterability of a liquid composition into cementitious materials such as concrete and mortar. Treated quicklime particles of the present invention manifest an unexpected and surprising hydration induction postponement behavior, as demonstrated through calorimetric testing.
