Road oils are Hquid asphalt materials iatended for easy appHcation to earth roads. They provide a strong base or a hard surface and maintain a satisfactory passage for light traffic. Liquid road oils, cutbacks, and emulsions are of recent date, but the use of asphaltic soHds for paving goes back to the European practices of the early 1800s. 

Distillation (ASTMD402). Approximate amounts of volatile constituents are deterrnined by this test which is particulady appHcable to cutback asphalt and road oils. 

The principal use of coal tar ia paviag is as a seal coat to bitumea paviag. Asphalt for paviag comes ia several forms deteroiiaed by the iateaded appHcatioa, ie, straight asphalts called asphalt cements (AC), asphalt emulsioas, cutback asphalts, and road oils. 

Road oils are very fluid asphalts that are used to keep the dust down on dirt roads. They are only a small part of the asphalt paving market. 

The residua from which asphalt are produced, once considered the garbage of a refinery, have little value and little use other than as a road oil. In fact, the development of delayed coking (once the so-called refinery garbage can ) was with the purpose of converting residua to liquids (valuable products) and coke (fuel). 

In electric utilities, residual fuel oils, such as no. 4, have been used to process steam for electric plants (lARC 1989). Fuel oil no. 4 has been used in commercial and industrial burner installations that are not equipped with preheating facilities (Air Force 1989). In other industries, such as the maritime industry, plants and factories, and the petroleum industry, residual fuel oils have been used for space and water heating, pipeline pumping, and gas compression, as well as in road oils, and in the manufacture.

Asphaltic road oil a thick, fluid solution of asphalt usually a residual oil. see also Nonasphaltic road oil. 

Nonasphaltic road oil any of the nonhardening petroleum distillates or residual oils used as dust layers. They have sufficiently low viscosity to be applied without heating and, together with asphaltic road oils (q.v.), are sometimes referred to as dust palliatives. 

The coefficients for venturi meters, flow nozzles, and orifice meters vary with Reynolds number as shown in Figs. 10.7 to 10.10. The curve for an orifice meter shown in Fig. 10.10 covers an unusually wide range of both viscosity and Reynolds number. The fluids used were water and a series of oils up to a very viscous road oil, and for each fluid a number of different velocities were used, so that the curve represents points for many combinations of velocity and viscosity. Although the orifice plate may not be a standard beveled form, the value of C for high Reynolds numbers agrees closely with the value of C in Fig. 10.10 for a diameter ratio of 0.75.

Furol viscosity. The efflux time in seconds (SFS) of 60 mL of sample flowing through a calibrated Furol orifice in a Saybolt viscometer under specified conditions. Furol viscosity is approximately 1/10 of Saybolt Universal viscosity and is used for fuel oil and residual materials of relatively high viscosity. Furol is derived from the words fuel and road oils.
