Check the transporter’s manifest before it is unloaded to make certain the asphalt in the truck is the right type for the project. Unfortunately, some inspectors have found out too late that the wrong asphalt was pumped into the heater unit. Once again, this is the contractor’s responsibility, but it will delay the project and can easily be prevented. A copy of the manifest of each load of asphalt delivered on the job must be retained in the project folder.
