High Polymer Mixes for New and Rehabilitated Pavements

چکیده
Fall 2013 • Vol. 25 • No. 2 The exceptional fatigue and rutting resistance observed in section N7 made HiMA the material of choice in rehabilitating a nearby pavement test section that was completely failed. Oklahoma’s section N8 has a soft subgrade representative of native Oklahoma soil. The section was originally constructed in 2006 with 10 inches of asphalt over a stiff soil base, simulating lime stabilization. By the end of the three-year research cycle, the section was in poor condition and received a conventional repair. However, the 5-inch mill-and-inlay failed early in the next research cycle after only 31⁄2 million ESALs.

Mechanistic-Empirical Analysis of Asphalt Dynamic Modulus for Rehabilitation Projects in Iran
In the Mechanistic–Empirical Pavement Design Guide (MEPDG), dynamic modulus of asphalt mixes is used as one of the input parameters in pavement analysis and design. For in-service pavements, MEPDG method uses a combination of some field and laboratory tests for structural evaluation of asphalt layers in rehabilitation projects. In this study, ten new and rehabilitated in-service asphalt pavemen...

The Long Term Pavement Performance (LTPP) program is a 20-year study of inservice pavements across North America. Its goal is to extend the life of highway pavements through various designs of new and rehabilitated pavement structures, using different materials and under different loads, environments, subgrade soil, and maintenance practices. LTPP was established under the Strategic Highway Res...
