Features Roller-Compacted Concrete Beats Out Asphalt

Operating a 1.7-million-square-foot automobile manufacturing plant with 1500 employees requires a big parking area for both employees' and visitors' cars. At the new Honda Manufacturing of America plant, now under construction in Lincoln, Ala., the vehicle parking area will be 61 acres, including car parking areas, access roadways, and traffic areas at the plant's periphery to accommodate delivery trucks. Plant construction broke ground in 2000, with manufacturing scheduled to begin by early 2002. At this $440-million facility, Honda will prefabricate auto parts and assemble automobiles and engines. The plant is being built on a 1350-acre company-owned tract, so there is plenty of room for expansion. Read more

Using colored flowable fill to backfill utility lines provides excavation crews with a reliable and clear visual warning of potential hazards. Read more

Features Predicting Thermal Cracking in Bridge Deck Repairs

The increased traffic load on interstates and major highway systems has led to ever-shorter time requirements for the completion of deck repairs. Repair contractors often must pay penalties when roadways are not open to traffic on time. When concrete bridge decks are repaired, the required rapid strength gain results in a quick and significant temperature rise in the concrete. Many DOT requirements for opening roadways to traffic with concrete as little as 18 hours old leave no possibility for gradual cooling. As a result, the newly poured concrete repairs crack.
