Available in PDF, EPUB and Kindle. Book excerpt: To evaluate the public perception of pavements in Colorado, 24 individuals were driven over 69 pavement sections in the Denver Metro area. These individuals were asked to rate the pavement based on rideability and to determine whether that ride was acceptable or unacceptable. The 69 pavement sections that were rated include: 51 bituminous and 18 concrete sections, urban and rural roads, and 35 and 55 mph speed limits. These ratings were then scaled from 0 to 5, with 5 being the best ride. Using regression analysis, the scaled ratings were compared to the roughness of the pavement. The pavement roughness was measured by the Colorado Department of Highways using a Mays Index. The conclusions are: for bituminous pavements 10% of the public is unhappy at a present serviceability index of 2.50; for concrete pavements 10% of the public is unhappy at a present serviceability index of 2.21; and the public will tolerate rougher roads at slower speeds.

Download or read book Investigation of the Rutting Performance of Pavements in Colorado written by Timothy Aschenbrener and published by . This book was released on 1992 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of the rutting performance from plastic flow on 33 hot mix asphalt (HMA) pavements was performed. Air voids in the wheel path of 3.0% clearly distinguished pavements with good and bad rutting performance: air voids less than 3% rutted and air voids greater than 3% did not rut from plastic flow. Samples were recompacted in the Texas gyratory using the high and low efforts. Samples recompacted with air voids greater than 2.0% with the high effort or 3.0% with the low effort indicated good performance with respect to rutting. The air voids after the low effort of compaction correlated best with the air voids in the wheel path for high volume roadways. Component properties (aggregates, asphalt cements, gradation, etc.) did not reveal why the good pavements performed well and the bad pavements did poorly. Performance was directly tied to the void properties. Field verification should be performed throughout the project to provide indications of the future rutting performance of the pavements.
