One of the factors that most negatively impacts the operational phase of a highway is the appearance of potholes and subsidence in the wearing course. In most cases, these undesirable obstacles to traffic stem from poor or inadequate compaction of the subgrade on which they rest. Let\u2019s examine the causes of this phenomenon and some methods for repairing it.<\/span><\/p>\n

On the embankments that are not properly compacted or in which suboptimal materials are used<\/strong> Differential settlement often occurs over time and due to heavy traffic loads. This settlement is reflected in the road surface grade. In such cases, the solution under maintenance contracts has been to level the surface by laying an asphalt mixture. In the case of concrete pavements, the problem is more serious, since this rigid pavement adapts very poorly to differential settlement, leading to the cracking of the concrete slabs. Water enters through cracks in the slabs, accelerating the problem. Various methods have been tested for repairing concrete slabs, such as partial repair with resins, complete replacement of the slab, splitting the slab in two to accommodate movement, reinforcing the slab, etc. In other cases, the concrete slab has been replaced with spot repairs using asphalt.<\/p>\n

If the problem is widespread, it may be necessary to replace the concrete pavement with asphalt concrete. This solution was implemented on the A-2 between the Alhama de Arag\u00f3n exit and the Monegrillo River viaduct. In this case, the embankment was raised to a depth of 2 meters. The concrete pavement was demolished and crushed on site, and the crushed material was used as a subbase. A gravel layer and an asphalt concrete pavement were then laid on top of this subbase. It should be noted that this work was carried out with traffic alternating between the two lanes while work was being performed on the other.<\/p>\n

To minimize the impact on traffic, it is necessary to switch to another type of solutions that are faster to implement<\/strong> and that allow traffic to remain open<\/strong>. The most common solutions involve stabilizing the embankment by:<\/p>\n
