AbstractThe implementation of a pavement preservation program involves a learning curve with not only a determination to succeed, but also the courage to fail. Also, successful implementation of pavement preservation program requires knowledge of the performance of preservation surface treatments over time, which is critical to the select of candidate projects and the development of performance models for pavement management analysis. In addition, preservation surface treatments, such as chip seal, fog seal, microsurfacing, 4.75 mm thin or ultra-thin overlay, can not only repair certain pavement surface defects, but also change the surface characteristics of pavement and therefore affect pavement surface friction performance. Nevertheless, such information is currently not available but is essential for the Indiana Department of Transportation (INDOT) to evaluate the effectiveness of pavement preservation surface treatments. As a concentrated effort, this study focused on the long-term friction performance of preservation surface treatments, particularly those have been widely used and those have seen increasing use by INDOT.Based on the selected field pavement test sections, this study aimed to evaluate the surface characteristics, particularly the longterm friction performance for those surface treatments that have been widely used and have seen increasing use by INDOT, including chip seal, fog-chip, fog seal, rejuvenating seal, microsurfacing, ultrathin bonded wearing course (UBWC), 4.75-mm hot mix asphalt (HMA) thin overlay, and profile milling (or diamond grinding). The test sections for each type of surface treatment covered a wide range of traffic volume from light to high. The service life for the selected test sections varied from 6 months to 60 months. Friction testing was mainly conducted using ASTM E 274 locked wheel trailer. Surface texture testing was conducted using either the ASTM E 2157 circular track meter (CTM) or a laser scanner. Pavement roughness and noise tests were also conducted to address the smoothness and noise issues, particularly on microsurfacing. Detailed analysis was provided to evaluate the friction performance of 4.75-mm HMA overlays. It is believed that the test results and findings drawn from this study not only provides timely information for INDOT to improve its pavement preservation program, but also provides the original information for the potential readers to better utilize preservation surface treatments.

Comparative Analysis of Skid Resistance for Different Roadway Surface Treatments

“…A study by the Joint Transportation Research Program (Indiana Department of Transportation and Purdue University) investigated the effect of fog seal on road surface friction (Li et al, 2012). According to this research, skid resistance measurement decreased dramatically after the application of fog seal.…”

“…The reduction of deviation of friction measurements, however, shows that fog sealing leads to a more uniform pavement surface. The study by Li et al (2012) also shows that it normally takes the pavement surface friction about 18 months after a fog seal application to return into the original level of friction.…”

Macrotexture modeling and experimental validation for pavement surface treatments

“…Furthermore, they are often used as a wearing course on low volume roads [6] and they mainly affect skid resistance [7][8][9].…”

Surface Performance Characterization of Single-Layer Surface Dressing: A Macrotexture Prediction Model

“…Chip seals are often used as a wearing course on low volume roads (Li et al 2012). Chip seals are widespread because the construction operations are less expensive and faster than those necessary for other preservation alternatives (Wasiuddin et al 2012).…”

“…For chip seal solutions, a classification according to the number of layers of binder was proposed. Within each of these main groups (single/double or multiple binder application) there are several types of treatments that can be used as both first coat and reseal treatments and other ones that are adopted only as a reseal (TNZ 2005;Li et al 2012;Gransberg and James 2011;FHWA 2003;Holtrop 2008;Croteau et al 2005;Kucharek 2007;Shuler et al 2011;Nicholls 2002).…”
