The thermooxidative degradation of styrene-butadiene-styrene block copolymers having different structures and molec.wts. in the presence of asphalt was investigated under different ageing conditions using size exclusion chromatography and IR spectroscopy. The physicochemical properties of the polymer modified asphalts before and after ageing were determined and changes in these properties explained on the basis of the structural modifications arising as a result of thermal degradation. 20 refs.

ROAD PAVING WITH WASTE PLASTIC

It is briefly reported that a sixteen year old girl from British Columbia has received a gold medal and a 2, 000 US dollars scholarship at the 2002 Canada-wide Science Fair for PolyAggre Road, a proprietary road paving material she developed that uses 6% recycled plastic pellets from plastic bottles, 6% asphalt and 88% aggregate.

ASPHALT-RUBBER SETS THE BAR FOR MODIFIED BINDERS
Carlson D J

Asphalt-Rubber was first defined in 1988 by ASTM as "a blend of asphalt cement, reclaimed tyre rubber and certain additives in which the rubber component is at least 15% by weight of the total blend and has...


Products & Services
Road Construction and Paving Services
Road construction and paving services specialize in the building of roads, highways, interchanges, and associated utilities.
Paving Machines
Paving machines are used to pave roadways, walkways, or parking areas.
Pavers
Pavers are casted blocks utilized in hardscaping to create even, durable surfaces for people and vehicles. Common materials include concrete, stone, clay, and rubber, amongst others.
Monomers, Intermediates, and Base Polymers
Monomers, intermediates, and base polymers are starting raw materials or binders for the production of compounded resins, plastics and elastomers, paints or organic coatings, adhesives and sealants;
Asphalt Road Surfacing Materials
Asphalt road surfacing materials include asphalt concrete and chipseal, an asphalt layered surface coated with bituman. A road surface, or pavement, is laid on the ground and is used to provide a durable path for vehicles or foot traffic.
