Abstract
Abstract Asphalt pavements have been extensively used in highway system. However, a great number of asphalt pavements suffer from early distresses after servicing for about 2–3 years, which leads to frequent rehabilitation and increased maintenance cost. To understand the damage propagation principle and the correlated rehabilitation measure, the progress of pavement distress rehabilitation, structural performance, and damage assessment of asphalt pavements has been explored in the perspectives of materials and structures. The current advance on the parameters for describing the cracking and rutting of asphalt pavements has been introduced. The development tendency for the damage self-healing and rehabilitation, and structural assessment has also been discussed. The study can provide a scientific guidance for understanding the generally used structural damage rehabilitation measure and performance assessment methods of asphalt pavements.
Highlights
Until 2019, the total mileage of highways in China has reached 150,000 km, ranking first in the world
The major distresses that deteriorate the performance of asphalt pavements include the cracks, rutting, potholes, upheaval, corrugation, and shoving
Hollow fibers filled with solutions are compartmented to distribute the rejuvenator throughout the asphalt mixture for overcoming some of the problems associated with alternate asphalt pavement healing methods
Summary
Until 2019, the total mileage of highways in China has reached 150,000 km, ranking first in the world. To scientifically maintain and effectively extend the service life of pavements, pavement functional rehabilitation technology will develop from the perspectives of material performance enhancement, structural composition optimization, and repair-effect information [6,7]. The major contents summarize the rehabilitation measure of material and structural performance, and the method to assess the pavement service performance. Structural damage rehabilitation/performance assessment of asphalt pavements 439 and damage. It intends to provide scientific basis and technical guarantee for the whole life cycle maintenance management of pavement structures. The major distresses that deteriorate the performance of asphalt pavements include the cracks (fatigue crack, top-down crack, reflective crack, and block crack), rutting, potholes, upheaval, corrugation, and shoving
