Roadworks Rectification at Pontian, Johor, Malaysia

In response to localized pavement failures near Sekolah Agama Parit Jawa, Maccaferri Geosynthetic solutions emerged as the most suitable application for the situation. By strategically placing MacTex WF 6550.60 geotextile within the road base, this innovation addressed differential water movement and enhanced subgrade bearing capacity. Boasting an ultimate tensile strength of 65 kN/m, Maccaferri’s solution not only rectified the issue but also extended road lifespan, setting a new standard for sustainable road infrastructure.

The integrity of road infrastructure is the lifeline of communities, ensuring seamless connectivity and smooth transportation. However, localized pavement failures can disrupt this flow and compromise safety. A prime example occurred along the road adjacent to Sekolah Agama Parit Jawa in Pontian, Johor, where settlement issues arose due to the varying rates of expansion and contraction, alongside the relative movement of water within different layers. The road base plays a pivotal role in distributing vehicular loads across the subgrade soil. When loads aren’t evenly spread over a soft subgrade, the road is susceptible to distress and failure. The uneven settlement observed along the road near Sekolah Agama Parit Jawa underscored the urgency to find a sustainable solution that could mitigate these issues and enhance road resilience.

Maccaferri Geosynthetic solutions, a pioneering approach that not only addresses pavement failures but also bolsters the overall robustness of road structures. By strategically placing geosynthetics as tensile elements within or at the base layer, the bearing capacity of the subgrade is significantly increased. This, in turn, extends the road’s lifespan, reducing maintenance costs and ensuring the uninterrupted flow of traffic. In the case of the road adjacent to Sekolah Agama Parit Jawa, a comprehensive remedial approach was undertaken. The installation of Maccaferri’s MacTex WF 6550.60, a premium woven polypropylene geotextile, emerged as the ultimate solution. This geotextile serves a dual purpose by providing separation and reinforcement functions, addressing the root causes of the localized pavement failures. The MacTex WF 6550.60 boasts an impressive biaxial ultimate tensile strength of 65 kN/m, underlining its capability to withstand significant forces and pressures. Its application within the road base addresses the differential movement of water and ensures a stable base layer, effectively eliminating the chances of distress and failure due to uneven settlement.

The localized pavement failure served as a catalyst for innovation in road maintenance. Maccaferri Geosynthetic solutions demonstrated their mettle by providing a comprehensive remedy that not only addresses the immediate challenge but also enhances the overall road resilience. Through the strategic placement of MacTex WF 6550.60 geotextile, the road’s bearing capacity is reinforced, and its durability extended, setting a benchmark for sustainable road infrastructure solutions
