Abstract
Pavement distresses are among the major problems that affects to a decisive extent on the using (operational capacity) the roads and reducing their service life. Therefore, its require to limitation this distresses and knowing the reasons that lead to appearing this distresses and give the correction during the construction of roads. The major distresses is the rutting which increases at intersections and the check points when the vehicle is stopping. The reinforcement pavement layer became an important step of design and the reconstruction of pavement layers which is control of almost distress, reduce the maintenance cost, and provide long service life of roads. In this study will study using the mats of palm fronds in reinforcement pavement layers instead industrial materials due to existence the palms with large quantity in Iraq. The result display the using the mats of palms fronds reduce the rutting percent 96.7, 88.3, 83.3 at 40, 50, 60 ºC respectively at surface course according the test by wheel track machine.
