SUBSTANDARD MATERIALS FOR PAVEMENT CONSTRUCTION --14TH ARRB CONFERENCE, 28 AUGUST - 2 SEPTEMBER, 1988, CANBERRA, ACT, AUSTRALIA; PROC. PARTS 1 - 8

If local, substandard materials can be used in pavements in place of more expensive conventional materials, considerable economic savings are sometimes possible. However, these substandard materials are often difficult to evaluate and may invalidate common pavement design assumptions. Also these materials may adversely affect the pavement performance. Some specific pavement problems due to poorly graded and uncrushed aggregate in asphalt concrete, cohesive fines in aggregates, dune sands and coastal deposits, shales, laterite gravels, and duricrusts are reviewed in the paper. These substandard materials may also require adjustments in construction procedures to accommodate their characteristics. The economics of using substandard materials in pavements must be balanced against the additional potential difficulties of adequately evaluating the materials, designing to account for their characteristics, and adjusting construction procedures for them. Often the performance of the pavement will be adversely affected by these materials, and this potential loss in performance must be balanced against the cost savings (a).
