This particular Colorado study was initiated to gather and analyze facts on the performance of embankments constructed without moisture and/or density control, and to draw specific conclusions which might assist designers of future roadway embankments., H.

Twenty-seven flexible pavement projects 15 to 16 years old were investigated to correlate performance with moisture, traffic, soil, and designed conditions. The findings of this study provided a basis for determining the structural adequacy of Colorado highways by means of serviceability Index values., prepared by State Department of Highways, Division of Highways-State of Colorado, Planning and Research Division ; in cooperation with U.S. Department of Transportation Federal Highway Administration, Bureau of Public Roads., "May 1970.", Includes bibliographical references (leaf 66)., Final report, Print version record.

Since 1966 an evaluation project has been underway to study asphalt pavement by measuring its dielectric properties. Originally, this project was directed toward asphalt content, however, it was determined that asphalt density had a relationship to dielectric properties., Denis E. Donnelly, Herbert N.

The recent attention to ecology has led to many changes in road construction. One change has been in the emphasis on roadside planting or erosion control and highway beautification. In Colorado, many roads are being constructed with steep side slopes in both cuts and fills. These slopes are prone to both water and wind erosion, so it is important that vegetation be planted quickly to hold the topsoil in place. This not only makes the highway seem less of an incursion on the scenery, but also aids in the maintenance of roads, preventing culverts from being stopped up and aiding the drainage systems in working properly to prevent hazardous conditions to the people using the highway., Robert F.
