Every year, the Government of Jamaica spends millions of tax dollars on road repairs, especially potholes whose lifespan lies between rainfalls. These financial losses are often caused from a lack of knowledge involving science, mathematics, and the art of fixing potholes. Potholes are a common problem on roads worldwide, and especially here in Jamaica, resulting from the wear and tear caused by traffic and weather conditions.
Fixing potholes, however, is more than just filling a hole in the ground – it’s a blend of scientific knowledge and practical techniques that ensure durability and safety. FORMATION OF POTHOLES Understanding pothole formation is crucial. They typically start when water seeps into small cracks in the road surface.
In tropical/dry tropical maritime climates that Jamaica falls under, the asphalt can soften and become more pliable, making it susceptible to damage from heavy traffic. The intense heat can cause the asphalt to expand and contract, leading to cracks and, eventually, potholes, as vehicles drive over these weakened spots. Some of the common factors that contribute to pothole formation are wear and tear, poor drainage, improper road maintenance, use of substandard materials, and extreme weather conditions.
SCIENCE OF REPAIR The science behind fixing potholes lies in materials and methods used to ensure longevity. Common materials include: 1. Hot mix asphalt: Preferred for permanent repairs.
This asphalt is heated to a high temperature before a.
