Mastic asphalt is a type of asphalt that differs from dense graded asphalt (asphalt concrete) in that it has a higher bitumen content, usually around 7–10% of the whole aggregate mix, as opposed to rolled asphalt concrete, which has only around 5% asphalt. This thermoplastic substance is widely used in the building industry for waterproofing ...
In 1887, Amzi Barber, an American businessman known as "The Asphalt King", secured a 42-year monopoly concession from the British Government for the Pitch Lake for his company, Barber Asphalt Paving Company. It was from this source that many of the first asphalt roads of New York City, Washington D.C., and other Eastern U.S. cities were paved. [6]
ASTM 4869-03 now includes the non-perforated felt referred to in ASTM D226-97a which will be phased out. ASTM 4869-03 includes a liquid-water transmission test (shower test) and dimensional stability limits (wrinkling) which ASTM D226-97a does not include. [8] Type 1 - #8. Formerly ASTM D4869-93 Type I; Type 2 - #13. Formerly ASTM D226-97a Type ...

The most common diluent used to dilute bitumen is natural gas condensate (NGC), especially the naphtha component. [5] Due to insufficient quantity of natural gas condensate in Alberta, bitumen shippers also use refined naptha and synthetic crude oil (SCO) as diluent, and import a considerable amount from the U.S. [6] Although SCO requires a higher volume percentage to achieve the same ...
Chip seal products can be installed over gravel roads to eliminate the cost of grading, road roughness, dust, mud, and the cost of adding gravel lost from grading. Adding chip seal over gravel is about 25% of the price of resurfacing with asphalt, $170,000 for a 4-mile project done in Minnesota [6] compared to $760,000 had it been redone with ...
