The warm mix additive and the anti-stripping agent were added at a dosage rate of 0.5 percent of the asphalt cement. The latex additive was added to the mix at a dosage level of 1.0 percent. The quantity of asphalt emulsion used for the four emulsion mixes was 1.75 percent, while for the foam tests, the quantity of asphalt cement was 1.25 percent.

mix asphalt and warm-mix asphalt laboratory compacted specimens along with field compacted specimens were assessed for cracking and rutting performance using the Illinois Flexibility Index Test and Hamburg Wheel-Tracking Test, respectively. Results showed that warm-mix asphalt mixtures have a lower cracking potential than hot-mix asphalt mixtures.

Rutting of Caltrans Asphalt Concrete and Asphalt-Rubber

Overlays are the primary rehabilitation strategy for flexible pavements that have cracking or ride quality problems. The traditional material used for overlays of flexible pavements is dense graded asphalt concrete (DGAC). Caltrans has also used asphalt-rubber hot mix gap-graded (ARHM-GG) for overlays for approximately the last 20 years (1).

Polished Aggregate | Washington Asphalt Pavement Association

Micro-milling of the pavement can restore or enhance skid resistance. A thin lift overlay with a 3/8″ minus hot mix asphalt or a thicker overlay with 1/2″ minus HMA will provide a new, highly skid resistant surface, while also adding strength to the pavement structure.

PDF NS-647 - Mitigation of tenting of transverse cracks and

Abstract: The goal of this project was to identify common features of good and poorly performing asphalt pavements. The types of asphalt pavements included in the study were grouped into four categories: new construction, crush & shape with hot mix asphalt (HMA) surface, mill & resurface, and HMA overlay. Deterioration relationships were used to

Life-cycle cost analysis of SMA pavements and SMA

The objective of this research project was to provide a comparative cost analysis of pavements constructed using stone matrix asphalt (SMA) mixtures versus those built with Wisconsin Department of Transportation's (WisDOT?s) conventional hot-mix asphalt (HMA) mixtures, based on parallel life-cycles (inclusive of any required maintenance) and resultant performance.
