Extensive damage caused by faulty or leaking bridge deck expansion joints has resulted in progressively increasing maintenance and rehabilitation costs. To avoid these problems, more than half of the state highway departments have developed guidelines for the design and construction of integral abutment bridges.
FRANCIS E. GRIGGS, JR.
Preserving the accumulated knowledge based primarily in practice is an important part of furthering the profession of civil engineering.
SAMUEL R. MALOOF
Pathogen reduction and sludge stabilization in the treatment of sewage sludge prior to land application may be best achieved by using a process sequence of mesophilic composting or anaerobic digestion followed by electron treatment.

The first spreadsheet designed for use on microcomputers was introduced in 1978. Since that time, business managers have made extensive use of these new electronic “tools,” resulting in documented increases in productivity. Practicing engineers have been relatively slow in adopting this technology. Specifically, little use has been made of the powerful graphics capabilities these programs possess.

Reinforced lightweight concrete one-way slabs made using perlite, styropor and pumice lightweight aggregates and aerated concrete slabs can behave favorably in terms of load carrying capacities, deflections, initial crack loads and crack widths.
RALPH B. PECK
Thorough investigations of site conditions and construction records should have precedence over stability analyses for determining the safety of embankment dams.
ALI TOURAN
Saving on formwork labor costs which are the leading costs in concrete construction should be a design objective.
