Over a half-million workers are exposed to fumes from asphalt, a petroleum product used extensively in road paving, roofing, siding, and concrete work. When hot asphalt is applied in a molten state, it generates toxic fumes. Workers exposed to asphalt fumes are at risk of developing headaches, rashes, cough, and possibly cancer.

With all types of asphalt, a certain amount of cracking is inevitable. The secret is to fill the cracks before they expand and turn into potholes or larger areas of crumbling pavement. There are two types of crack filler that can be used on any asphalt or concrete surface.
Three basic types of trucks are used to haul the asphalt concrete from the plant to the job site: rear-dump trucks, live-bottom conveyor trucks, and bottom-dump trucks. True Regardless of the type of truck used, the trucks should be insulated and covered to increase heat loss during transportation.
Filler is a widely used material in the production process of plastic products. Filler is used to change the properties of the original plastic. By using plastic filler, manufacturers can save production costs as well as raw materials.
Liquid fillers, in general, aren’t built the same way. Even though one type of filler has more advantages over another type, a machine’s efficiency should not be the only factor to consider when getting one. The cost of purchasing and operating these filling machines must be taken into account, as well as their design and construction.
A note on terminology is worth making at this point – ‘asphalt’ is a generic term used to describe a range of road surfacing products containing primarily bitumen and mineral aggregates. A few alternative terms exist including hot mix asphalt (HMA) and asphalt concrete (AC). In this book the term ‘asphalt’ will be used throughout.

We also recycle asphalt shingles and concrete - turning these materials into new asphalt pavement. Recycling helps us produce numerous custom mixes of asphalt for a broad range of project types.
Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, as well as the core of embankment dams.
This allows the plant to be used for regular asphalt concrete production when it is not being used to produce Epoxy Asphalt. What are the optimum aggregate properties for Epoxy Asphalt? Since the aggregates make up about 94% of the paving mix it is essential to use the best available aggregate to obtain a durable pavement with good flexural life.
