1. The relative economics of rigid and flexible paving are constantly changing
with the improvement of design features and construction techniques and with
the development of new products. These factors are of significant importance
in both new pavement construction and in the rehabilitation of existing
pavements. All projects require careful study and evaluation of the in-place
materials and the proposed construction materials. For the purposes stated,
NAVFAC wishes to carefully review the design cross sections of all major
2. MIL-HDBK-1190 requires that alternate designs be prepared for both concrete
and flexible pavement of all noncritical areas and that the contractor be given
the option of providing either. There are no quantity limitations on this
