Investigation of premature pavement distresses" by K

Al-Ahsa Road, which is located in north-eastern Riyadh, was constructed in March 1981 as part of the Fourth Stage of the Riyadh Urban Road Improvement Project. The road is 2.85 km long. Reconstruction consisted of the installation of a 170 mm thick asphalt basecourse and a 40 mm thick hotmix asphat wearing course. Several months after construction, following the first winter, shrinkage and

Capturing mixed-mode cracking of asphalt concrete using

Reflective cracking of asphalt concrete has been shown to be a combination of both opening (Mode I) and sliding (Mode II) cracking. The Arcan test configuration was developed at Southeast University to test Mode I, Mode II and three levels of mixed mode. This research used two asphalt concrete mixtures with the same asphalt cement but with two gradations: AC-20 and AC-10; four loading rates: 0

Compacting Hot Mix Asphalt Pavements: Part I | Roads & Bridges

Tests have shown that reducing the air-void content of a given asphalt-concrete mix from 8% to 5% can double the fatigue life of the pavement. Thus, for a given thickness of HMA as part of the pavement structure, the ability of the mix to carry load can be increased significantly when the mix is compacted to a lower air-void content.
