Asphalt and bitumen tanker trailers are professional constant-temperature heat-preserved transport equipment specially designed for high-viscosity thermal industrial materials. Different from conventional liquid cargo, asphalt, modified bitumen and coal tar have special physical properties: they maintain fluidity only at high temperature, and will gradually thicken, condense and completely solidify at normal temperature. Ordinary standard tankers cannot solve the problem of material solidification, which will lead to unloadable cargo and overall material scrapping, causing huge economic losses.

TITAN heat-preserved asphalt tankers are professionally developed for road engineering and municipal infrastructure projects, widely used in highway construction, bridge pavement, urban road renovation, daily highway maintenance and large-scale water conservancy engineering construction. They are mainly responsible for the long-distance transportation and short-distance turnover of liquid asphalt, modified bitumen, coal tar and heavy industrial oil, ensuring that the thermal materials maintain stable fluidity from factory delivery to on-site construction, and guaranteeing uninterrupted progress of engineering projects.

3.2 Thermal Insulation Structural Design

To solve the core industry problem of heat loss and cargo solidification during long-distance transportation and on-site standby, TITAN asphalt tankers adopt a multi-layer composite thermal insulation structure. The interlayer of the tank body is filled with high-density rock wool and fiberglass thermal insulation materials with ultra-low thermal conductivity. These high-performance thermal insulation fillers can effectively isolate external cold air and temperature changes, greatly reducing internal heat loss and slowing down the cooling and solidification speed of asphalt materials.

The outer layer of the thermal insulation structure is covered with thickened stainless steel protective cladding, which integrates waterproof, anti-corrosion, wear-resistant and anti-aging functions. This integrated protective structure can stably lock the internal temperature for a long time. Even in severe cold winter environments, long-distance cross-city transportation and long-time on-site standby scenarios, it can effectively prevent asphalt condensation and solidification, ensuring that the cargo always meets construction fluidity standards.

3.3 Heating System & Core Functional Features

All TITAN asphalt tanker trailers are equipped with independent diesel burners and full-coverage circulating heating pipeline systems, serving as a supplementary guarantee for material fluidity.
