use of recycled plastic in asphalt and concrete pavement

AP-T351-19 Viability of Using Recycled Plastics in Asphalt

trials involving the use of recycled plastic in roads. It was found that waste plastic can act as a partial aggregate replacement in bituminous mixes, and a binder extender without having any significant influence on the properties of the asphalt mix. However, not all recycled plastics are suitable for bitumen modification at high temperatures.

Using Recycled Concrete in MDOT's Transportation

The recycling of concrete pavements—crushing of old concrete slabs and reusing the crushed material in some other pavement application—has been used in the U.S. since the 1970s (Hoerner et al. 2001). At that time, common reasons for concrete recycling were noted to be

RECYCLED WASTE PLASTIC FOR EXTENDING AND

Recycling in Asphalt The primary material recycled into asphalt mixtures is recycled asphalt. Reclaimed Asphalt Pavement (RAP) is commonly stockpiled, crushed, tested and recycled back into new asphalt at the production plant (Austroads ). Typically, 10-20% of RAP is incorporated, with higher

Differences Between Concrete and Asphalt Pavement

Differences Between Concrete and Asphalt Pavement. Historically, pavements have been divided into two broad categories, rigid and flexible. These classical definitions, in some cases, are an over-simplification. However, the terms rigid and flexible provide a good description of how the pavements react to loads and the environment.

Present and Future Developments in Asphalt Paving

More recycling. Asphalt paving is already one of the top recycled products in use. This trend is definitely here to stay, and poised to increase. It's already easy and often simpler to use recycled asphalt than to bring in new asphalt for a paving project, and the recycling process will only get more efficient as technology improves.

PDF SEPTEMBER TECHNICAL NOTE Use of Recycled Materials

Reclaimed Asphalt Pavement. Milled or excavated asphalt pavement, known as RAP, obtained from the road and other sources can be collected as a co-mingled stockpile (Figure 4), processed by crushing and screening to a graded material, free of contamination, ready for use in new asphalt manufacture. It is estimated that

The mixture can range from 100% recycled glass to 20% glass and 80% stone for heavier vehicular loads and longer service life. Bound recycled glass pavement is extremely porous, with void space of 39-47% (more than double that of porous asphalt and pervious concrete), reducing the rate of clogging and the need for maintenance.
