Overview
How to Stabilize Pavement Base for Heavy Traffic Loads?
Pavement systems must support repeated traffic loads while maintaining structural integrity over their design life. In highways, industrial roads, logistics yards, and other heavy-duty pavements, the base layer plays a critical role in distributing loads and protecting the underlying subgrade.
When pavements are constructed over weak or variable ground conditions, conventional granular bases can experience lateral movement, rutting, and deformation under repeated loading. These conditions can affect pavement performance and lead to increased maintenance requirements over time.
With extensive experience in ground engineering and soil stabilization, Strata provides solutions that improve the performance of pavement base layers in challenging ground conditions. By incorporating cellular confinement technology such as StrataWeb®, the base layer can be reinforced to maintain stability and effectively support traffic loads.
Advantages of pavement base stabilization
Engineering Approach
Pavement base stabilization is implemented by installing StrataWeb® within the base or sub-base layer over the prepared subgrade. The system forms a cellular confinement structure that holds the granular infill material within interconnected cells.
After placement, the cells are filled with suitable aggregate or other approved infill materials and compacted to form the base layer. The cellular structure confines the infill and limits the lateral displacement of the aggregate particles when subjected to traffic loads.
Under loading, the confined material works together with the cellular framework to create a stabilized layer that distributes stresses within the pavement structure. This interaction between the infill material, the cellular system, and the underlying soil helps maintain the structural behavior of the base layer under repeated traffic conditions.

Earth retention and soil stabilisation at Aamby Valley, Lonavala
Aamby Valley is a hilly terrain and lies within the heavy rainfall zone of Lonavala. The courtyard area was enduring heavy erosion since the monsoons of 2013.
Strengthening of flexible pavement using StrataWeb® geocells in hilly terrain
The client proposed building an access road to the villas in the hilly terrains of the Nilgiris in Coonoor, Tamil Nadu. The challenges included difficulty for the movement of heavy construction machinery on the hilly terrain due to deep ruts. Also, heavy traffic movement was affected due to improper and insufficient drainage, especially during the monsoons. Therefore, there was a need to have a definitive solution for subgrade improvement.
