WORKSHOP TOPIC 4. EARTHWORK OR EXISTING ROADWAY PREPARATION

The workshop discussions covered all phases of design, construction beneath the pavement section including earthwork, appurtenances such as walls and drainage, use of waste materials, and geometric design standards. The discussions concluded that more effective use of on-site materials, improved construction procedures, and use of new materials and methods for the construction of appurtenant structurs will make a significant contribution to conservation of energy & materials in highway construction. Research for the improvement of procedures for investigation of cut-slope stability problems in earth and rock is suggested. The nationwide improvement of earthwork construction specifications could be a measure that could contribute to optimum use of energy and materials. The need for research to improve the efficiency of embankment construction is empasized. Materials and energy savings in roadway appurtenances result from the use of long-span corrugated plate structures, improved subdrainage inthe pavement section, reinforced earthwall construction, temporary erosion controls, and the use of recharge basins. The use of sanitary land fill in earthwork grading is discussed, as well as the modification of current geometric standards for earthwork.
