High, Cold Roadbuilding Calls for the Dragon: Tents are Used to Shelter Hot Mix While "The Dragon" Melts Ice to Prepare for Paving

This article discusses strategies implemented by construction firms to manage problematic conditions associated with high altitudes in the Peruvian Andes Cruz so that the InterOceanic Highway project may pass through the phase known as the Tramo II. Beginning June 2008, construction will be aided by heating tents that allow trucks holding prepared asphalt to function in cold weather, as well as a machine that heats the roadbed using gas jets. The project’s focus has shifted from roadway preparation to laying down asphalt, where fluctuating temperatures in this region compromise necessary conditions for paving so that time available for construction is shortened and mix batches must be adjusted with polymer additives. It is noted that implementation of heating tents and road heating machines have boosted productivity and lowered costs of production because they extend daily paving windows and increase possible amounts of batched asphalt.
