produced more than 1.0 billion t of construction aggregates in 1998. Concrete Recycling Product The bulk of the aggregates recycled from concrete—an estimated 68 percent—is used as road base. The remainder is used for new concrete mixes (6 percent), asphalt hot mixes (9 percent), high-value riprap (3

Use of plastic waste (poly-ethylene terephthalate) in

Due to the high volume of these bottles, more than 1 million m3 landfill space is needed for disposal every year. The purpose of this experimental study was to investigate the possibility of using PET waste in asphalt concrete mixes as aggregate replacement (Plastiphalt) to reduce the environmental effects of PET disposal.

For example, Min-nesota allows up to 3% asphalt cement by weight of aggregate and California has no limit on the relative proportions of re-claimed asphalt pavement (RAP) and RCA in their base materials.

first asphalt recycling research projects were done in-place in 1974 and hot-mix recycling was first done in 1977. In 1982, 43 percent of all our hot-mix contained some recycled materials and recycled hot­ mix now averages about $4.00 per ton less than vir­ gin mix. With the success of asphalt recycling being

How Plastic Asphalt Is Paving the Road to the Future

By mixing plastic pellets with hot, milled pavement, it melts into the aggregate and acts as the binding agent. While traditional pavement is ground up and reused at a later time, using plastic waste allows for an immediate recycling process. The pavement is milled, pulled into the machine, and is mixed with melted plastic on-site, creating a
