Items removed since the FP-03 include crib walls, previously in section 254, and
cutback asphalt, in subsection 702.02.
1) The Asphalt Institute describes a prime coat as "a spray application of a medium curing cutback asphalt or emulsified asphalt applied to an untreated base course".

Small surface cracks should be brushed full with a lean mix of sand and two to four percent by weight of
cutback asphalt. When poured, these small cracks are unsightly and usually the crack is not filled.
AK: ARL is producing a complete range of petroleum products comprising: "Liquefied Petroleum Gas (LPG), Export Naphtha, Premium Motor Gasoline (PMG), complete range of Jet Fuels (Jet A-1 and JP-8), Kerosene Oil, High Speed diesel (HSD), Light Diesel Oil (LDO), Jute Batching Oil (JBO), Furnace Oil including Low Sulphur Furnace Oil, variety of Asphalts including 60/70 and 80/100 grades,
cutback asphalts, Polymer Modified Asphalt, Mineral Turpentine Oil (MTT) and Solvent Oil etc.
It includes crude asphalt as well as the following finished products: cements, fluxes, the asphalt content of emulsions (exclusive of water), and petroleum distillates blended with asphalt to make
cutback asphalts. Note: The conversion factor for asphalt is 5.5 barrels per short ton.
Strategically located at Rawalpindi, ARL's configuration allows it to process from the lightest to the heaviest (23-65 API) Crudes to produce a complete range of Petroleum Products from LPG to Asphalt including specialty products such as Jet Fuels (Jet A-l, JP-8)
Cutback Asphalts, Polymer Modified Bitumen, Mineral Turpentine Oil, Jute Batching Oil and Solvent Oil.
Environmental concerns over the release of volatile organic compounds from solvent-based asphalt paving products (e.g.,
cutback asphalts) will aid demand for asphalt emulsions.
