Recycled Materials in Asphalt - makes the news

Recycling asphalt and using other recycled materials in asphalt makes environmental sense and saves billions of dollars in material costs. This is an area of the asphalt industry that continues to develop and mature in the USA and Canada.

The CBC video below describes how Vancouver will be the first city to use recycled plastic in asphalt paving.

"Vancouver will be the first-ever city to use blue box recycled plastics as asphalt mix on the city's roads, in a move engineers say is a green step forward.

Old plastic milk jugs, yogurt containers and other post-consumer recyclable material will be ground up and made into a wax which then used as a warm mix for asphalt.

"It's actually a lot like crayon wax and what we are doing with this is putting it in the asphalt which we are putting down today," explained Vancouver city engineer Peter Judd at a Kingsway paving site"

In the USA a recent survey concluded that the use of recycled materials in asphalt saved taxpayers more than $2.2 billion dollars. Read about the survey at the National Asphalt Pavement Associations website.

Making asphalt is like baking a cake. You measure all the right ingredients, mix them up and heat them for the final product. Asphalt starts with a mixture of sand and small and large rocks (called aggregate). Next, asphalt cement is heated and combined with the rocks — thus the name hot mix asphalt (HMA). The HMA must be kept pliable for proper installation, so asphalt facilities must be located near paving sites.

There are two basic types of plants used to manufacture hot mix asphalt:
Batch plants, which make asphalt in batches as needed to go straight to work sites
Drum plants, which make asphalt continuously and can store the asphalt for several days in heated storage silos.

You'll find common components in both batch and drum plants including:
•Cold feed bins — Accurately meter the different aggregates used in the mix to the drying drum. Aggregates are usually stored in stockpiles or they may be stored in large silos or bunkers.
•Asphalt cement storage — Asphalt cement is stored in tanks that meet stringent regulatory guidelines for spill prevention.
•Dryer drum — Dries and heats aggregates by tumbling them through hot air. In a parallel-flow drum, aggregates move in the same direction as the hot air. In a counter-flow drum, aggregates move in the opposite direction.
•Emission control system — Sometimes called a baghouse, this system traps and removes fine sand and dust particles and returns them to the mix.
•Storage silos — Drum mix plants must have silos since they produce asphalt continuously. Batch plants do not require a silo, but often have them to increase plant production. Storage silos are insulated and may be heated to prevent heat loss. A mix may be stored in a silo for days.
