ENGINEERING ECONOMY AND ENERGY CONSIDERATIONS SPRINKLE TREATMENT-HOW{ WHY AND WHERE

Recommendations are presented which were formulated on the basis of a literature review, on-site visits to construction projects utilizing sprinkle treatments in Texas and Virginia, and a representative workshop meeting. The sprinkle aggregate to be utilized as sprinkle stone should be based on established field performance indicating the aggregate to be non-polishing. Spread quantities and spread rates are recommended. Both plant mixing and road mixing techniques have been utilized to precoat the aggregate; emulsions, petroleum primers, precoating oil and asphalt cements have been utilized. Type D asphaltic concrete hot mix as specified by Item 340 is recommended; however experience indicates that type C may also be utilized. A self-propelled aggregate spreader equipped with tires without treads has been used for distribution of sprinkle aggregate. Breakdown rolling should begin immediately after placement of the aggregate. For measurement and payment, an approach is recommended which uses an alternate bid where prices for supplying an asphalt concrete with a specified polish value aggregate, and prices for supplying an asphalt concrete with no polish requirement together with a specified polishing aggregate sprinkle treatment. Recommendations are also made regarding evaluation of sprinkle treatment. An economic comparison is presented of sprinkle treated asphalt concrete and asphalt concrete containing a non-polishing aggregate. A cost comparison between open graded plant mix friction course and a sprinkle treatment is shown and the assumptions utilized for the calculations are listed.
