Pavement and Concrete Drying


Paving specifications do not allow placing a surface course pavement in cold weather.

A typical specification in the past has been the ambient temperature must be 10°C and rising before a paving operation can commence. The main reason for this is the concern that the cold asphalt in place will cool the newly placed surface course too quickly, before adequate compaction can be attained. More recent specifications put a lower limit of 2°C on the base asphalt.

Having an asphalt crew, plant and trucks wait for a temperature rise can be very expensive. A relaxed specification because of a construction deadline can be even more expensive in the long term.

IPR has several models of Infrared Heaters that can eliminate concerns of adequate temperature in the base course by pre-heating in front of the paver. The heating deck is produces enough radient heat to warm the asphalt to temperatures that would reduce premature cooling of the asphalt.


When concrete surfaces need to be dry prior to the applicaiton of waterproofing or the asphalt needs to be dry prior to the application of line markings, IPR has the equipment to effeciently heat the pavement and dry it so that the necessary process can be completed.
