| 摘要： | Field performance observations and tests were conducted on OGFC in four of six New England states. The data obtained included: distress surveys, friction measurements, surface texture values using two methods, air permeability and gradation of aggregate recovered from cores. These data were analyzed and the OGFC layer's performance evaluated. Conclusions regarding performance are set forth based on the data obtained and the results of an extensive literature survey. Recommendations concerning the placement of OGFC and subsequent maintenance are*presented. |
