Asphalt Road Repair & Ground Re-instatement Works

Asphalt Road Repair & Ground Re-instatement Works

This project involved the localized reinstatement, repair, and resurfacing of distressed asphalt pavement to restore structural integrity, improve load-bearing capacity, and ensure compliance with Singapore’s public safety and transport infrastructure standards. The works targeted specific damaged zones requiring immediate rectification due to wear, base settlement, or utility interventions.

Comprehensive Scope of Work & Operational Sequence

• Phase 1: Surface Preparation & Excavation The damaged asphalt segments were clearly marked and precisely cut using concrete saws to create clean, vertical edges, preventing further cracking of the adjacent stable pavement. All deteriorated asphalt and loose base materials were excavated and removed from the site. The sub-grade was then cleared of debris, leveled, and thoroughly checked for moisture or underlying structural weaknesses.

• Phase 2: Base Preparation & Asphalt Laying A high-quality asphalt premix was applied to the prepared area. The material was meticulously raked and leveled manually by skilled ground workers to achieve the precise pre-compaction thickness required, ensuring that the final layer would align perfectly flush with the surrounding existing pavement without leaving any hazardous ridges or depressions.

• Phase 3: High-Density Compaction To achieve maximum aggregate interlocking and eliminate air voids, a heavy-duty 350kg Reversible Plate Compactor was deployed. The equipment’s high-impact vibration and forward/reverse maneuverability allowed the operator to execute multiple systematic compaction passes, even within the confined borders of the repair zone. This process ensured deep compaction from the sub-base up to the wearing course, preventing future shifting, water ingress, or premature rutting under heavy traffic loads.

• Phase 4: Site Clearance & Safety Handover Following successful compaction and level verification, the site was cleared of all temporary support materials, sandbags, and equipment. The newly reinstated surface was left to cure completely, meeting all local Workplace Safety and Health (WSH) guidelines before being safely reopened for regular use.
