This test method sets out the procedure for determining the accuracy of road speed indicators used on bitumen sprayers. The road speed of the bitumen sprayer is used in conjunction with the pump volumetric output to enable bituminous materials to be sprayed at the design application rate. This test method also sets out the procedure for determining the repeatability, accuracy and correction factors of road distance indicators for bitumen sprayers that have a distance indicator.
