Durability of Diamond Ground HMA with and w/o Tack Coat

The proposed research will identify several duplicate Hot Mix Asphalt paving projects around the state in different climate/traffic areas. Duplicates are needed to ensure adequate sites are included in the research project as evaluation of diamond ground tacked versus untacked areas will only be done based on smoothness corrective action areas per the contract. Upon completion of smoothness acceptance testing/identification of corrective work areas, different areas in the same travel lane would be designated to remain uncoated with tack. Sites would be monitored annually, with performance monitored through visual distress assessment/photos. Sand patch (surface texture testing) would also be performed to document surface texture changes from year to year
