Modified Chip Seal Surface Treatments vs. Conventional Chip Seal Surface Treatments

摘要

The scope of this study was to evaluate modified types of chip seal surface treatments and to compare these modifications to the conventional chip seal surface treatments currently used on North Dakota roadways. The Materials and Research Division of the North Dakota Department of Transportation monitored and evaluated the following items: (1) Evaluation of different methods of chip seal placement; (2) Loss of aggregate from the pavement surface; and (3) Evaluate performance of different types of asphalt material. Material and Research evaluated this experimental project for a period of five years.
