EVALUATION OF 1977 ASPHALT CONCRETE SPRINKLE TREATMENTS
This report discusses results of a project held in 1977, using six projects selected from the Primary Highway Surface Restoration Program for sprinkle treatment research. A Bristowes Chip Spreader, imported from England, became available for use by Iowa contractors during the 1977 construction season. Conclusions from the research project include the following. 1. Sprinkle treatments are an effective means of providing pavements with high quality frictional properties. 2. Fine material in the sprinkle aggregate is detrimental. A coarser one size aggregate yields the best sprinkle applications. 3. Sprinkle aggregates should be produced from hard, durable materials with a history of good frictional properties. 4. Good coating of the sprinkle aggregate is achieved more consistently in batch plants than in drum plants. 5. Sprinkle treatments result in a substantial increase of macrotexture. 6. Sprinkle treatments may result in a monetary savings in construction of pavements where special aggregates are required to assure durable friction characteristics. 7. Sprinkle treatments conserve high quality aggregate.
