How should asphalt mix delivered to the site be covered until unloaded to the paver?

The use of tarpaulins to cover asphalt mix delivered to the site until it is unloaded to the paver is the most suitable option due to several important factors. Tarpaulins are typically made from durable, weather-resistant materials that provide excellent protection against environmental elements such as rain, wind, and extreme temperatures. When asphalt is exposed to moisture or excessive heat, its properties can be adversely affected, impacting the quality of the mix when it is laid down.

Additionally, tarpaulins are flexible and easy to handle, allowing for quick covering and uncovering as needed during the unloading process. They ensure that the asphalt mix remains at an optimal temperature and consistency, which is crucial for achieving the desired compaction and bonding with the underlying materials during paving.

Other materials like plastic sheets might not provide adequate protection against UV rays or might not have the strength required for heavy-duty site conditions. Wooden covers could be cumbersome and less efficient in covering the loads quickly. Metal sheets, being heavy and rigid, may be impractical for rapid covering and uncovering, in addition to potentially posing safety hazards if not managed correctly.

In summary, tarpaulins strike an ideal balance of protection, versatility, and convenience, making them the preferred choice for covering asphalt
