The work described here is concerned with achieving improved high temperature and low temperature performance of rubber modified asphaltic concrete
mixes, taking into consideration the compatibility, crumb rubber particle size and distribution of the asphalt-rubber composition.

The paving repairs include removing the top layer of deteriorated pavement, doing extensive subsurface repairs as needed, and then resurfacing the roadway with a new layer of asphaltic concrete
This $10 million rehabilitation project resurfaced nearly 20 kilometers (160 lane-kilometers of roadway and 26 structures) with Superpave asphaltic concrete
Demand for construction aggregates used in the production of asphaltic concrete
will grow the fastest of all major application categories, resulting from growth in road building and maintenance projects and increases in nonbuilding construction expenditures around the world.
Because of advances in new road construction and existing road improvement and repair, global sales of aggregates for road base and coverings, and asphaltic concrete
applications are expected to accelerate through 2017.
The largest decreases were for roofing granules (43 percent), asphaltic concrete
The use of virgin polyethylene as an additive to asphaltic concrete
is not new; however, two new processes also use recycled plastic as an asphalt cement additive:
The project includes milling, removal and replacement of approximately 100,000 tons of asphaltic concrete
, for which Meadow Valley plans to employ its portable crushing, asphalt production and paving equipment.

It is estimated that about 44 percent of construction sand and gravel was used as concrete aggregates; 23 percent for road base and coverings and road stabilization; 14 percent as construction fill; 12 percent as asphaltic concrete
aggregates and other bituminous mixtures; 3 percent for plaster and gunite sands; 1 percent for concrete products, such as blocks, bricks, and pipes; and the remaining 3 percent for filtration, golf courses, railroad ballast, roofing granules, snow and ice control, and other miscellaneous uses.
