Hot-lay bituminous material is commonly used on roads and streets as it has a quick cooling time.  It is made up of a combination of stone, sand or gravel and asphalt cement.  This mixture is heated to around 150-160°c and poured to create a very flexible surface that can withstand extreme weather conditions.

We offer certification on Hot-Lay from the following awarding bodies: SQA, SWQR.
