Abstract

The paper reviews methods, materials, equipment and results to date of sprinkle treatment within the state. The Iowa Department of Transportation formerly the Iowa State Highway Commission, made its first attempts at sprinkle treatment of fresh asphalt concrete in 1974. Increased emphasis in mix design of asphalt mixes and aggregate selection of durable non-polishing materials has generated costly restrictions on the use of local materials. During the summer of 1975, a dual spinner, tail-gate spreader was mounted on a standard departmental dump truck to attempt additional sprinkle treatment on a section of Iowa 7 west of Ft. Dodge. The dump truck equipment was marginally satisfactory, but results of increased surface skid texture and durability were well demonstrated. On 1976 a new, current order dump truck was modified with an auxiliary transmission and a set of slick surfaced tires, and dual spinner spreader was mounted to again attempt surface sprinkle treatment, which was conducted in 1977.
