Abstract

Asphalt pavements are increasingly susceptible to premature failures such as potholes, which not only escalate maintenance costs but also pose considerable road safety risks with disaster-related implications. Potholes have been identified as major contributors to vehicular damage, motorcycle accidents, and pedestrian injuries, emphasizing the urgency for preventive technologies that enhance pavement durability. A primary cause of these failures is insufficient thermal retention of asphalt mixtures during transportation, leading to inadequate compaction and weak interlayer bonding. This study proposes and evaluates a thermally insulated dump body that incorporates high-performance aerogel between double-layered steel plates to minimize heat loss during transit. Field trials demonstrated that the insulated dump body effectively maintained asphalt mixture temperatures up to 160°C at placement, mitigating temperature drops exceeding 65°C compared to conventional dump bodies. Laboratory tests confirmed notable improvements in mixture properties: a 1.7% increase in compaction density, a 35% enhancement in indirect tensile strength, and a 37% gain in toughness. These enhancements directly translate into improved resistance to thermal cracking and fatigue-induced degradation, significantly reducing the risk of pothole formation. By extending pavement lifespan and lowering maintenance costs, this technology contributes to improved roadway safety and aligns with national disaster prevention objectives. Accordingly, this study recommends nationwide adoption via policy-driven initiatives, including its designation as certified public maintenance equipment, linkage with pilot procurement programs, and phased implementation of mandatory use standards.
