Estimation of Low-Temperature Performance Grading of Modified Asphalt Binders Using the Critical Stress Intensity Factor
Publisher: American Society of Civil Engineers
Abstract: Cracking in pavements due to low temperature is the predominant distress in cold climate areas. The bending beam rheometer (BBR) test is typically utilized to determine the low-temperature performance of the asphalt binders. ...
Evaluation of Work Zone Road User Cost of Pavements Based on Rehabilitation Strategy Approach
Publisher: ASCE
Abstract: Life cycle cost analysis (LCCA) is a common tool to select road pavement type. In the pavement type selection process, most government agencies consider the costs of initial construction, maintenance, and rehabilitation; ...
Mechanical Performance of Hot-Mix Asphalt Modified with Porous Nanosilica Aerogels
Publisher: American Society of Civil Engineers
Abstract: Asphalt pavements are under extreme strain from high-volume traffic with ultraheavy axle loads, leading to rutting, fatigue, and moisture damage that reduces the useful life of asphalt mixtures. Studies have suggested that ...
