ASPHALT ANSWERS
Proper training is essential to ensuring the distributor truck pays for itself
high temperature mixtures such as AC or even rubber infused material , as they will set up much quicker . All of today ’ s units have a cleanout procedure that will keep the asphalt flowing freely . One tip given to me years ago is to spray the rear of the unit with biodegradable cooking oil through a pump sprayer . This way , a steam cleaner will remove most of the overspray and keep your unit much cleaner . The next area of importance is the spray nozzles . As you are aware , there are different size nozzles for different application rates . The nozzle number that corresponds with the application rate varies among manufacturers , so refer to your manual for the correct nozzle . If you are trying to spray heavy through a nozzle designed for light spray , the asphalt will atomize . If you are spraying light through a heavy spray nozzle , the material will only drip out , not giving you the optimal coverage . These nozzles spray with a “ V ” pattern and create what we will call a “ triple lap ” coverage , which is to say that the spray pattern will overlap , ensuring complete coverage . To achieve this , each nozzle must be turned at a 30 degree angle to the spraybar . When changing or cleaning nozzles , be sure to re-install at the correct angle . Keeping these nozzles clean will also ensure complete material coverage . Proper use of the asphalt distributor will allow you to have a profitable piece of equipment for years to come . Don ’ t believe me ? Take a peek at the market for a good used distributor . It literally pays to take care of your distributor .
