A high-cure crumb rubber modified asphalt (HC-CRMA) binder suitable for use in dense-graded mixes can be produced through a combination of high temperature …
The pore water pressure in asphalt pavement would increase with the increasing vehicle speed. The pore water pressure in pavement at depth of 4 cm is higher than it at depth of 10 cm. The permeability of asphalt mixture at different hydraulic pressures was obtained.
Established in 1990, Cooper Technology is a British company and one of the world leaders in the design and manufacture of high performance testing equipment for asphalt, bitumen, concrete, cement, soil and aggregates used in civil engineering.

uting to reduced pavement performance of America's high ways, particularly premature wheel path rutting of asphalt con crete (AC) surfaces. In 1985 AASHTO approved a resolution that, among other things, objected to the introduction of higher pressure truck tires, and subsequently established the Task Force on High Pressure Truck Tires (J).

softening in asphalt pavements, and freeze-thaw damage, joint deterioration (spalling), and scaling in concrete pavements. To prevent cold weather-related distresses in concrete pavements, both the designer and contractor must be aware of a few key considerations, so that the inherent long life of a concrete pavement can be fully realized.
