For nearly nonstop performance, strength, and visual impact, few plants compare to ornamental grasses.Unlike lawn or turfgrass varieties, ornamental grasses are meant to grow—not be cut or mown—and most are not used as ground covers. Once you start landscaping with ornamental grasses you will be amazed by how many varieties, sizes, shapes, and colors are available.

Marshall Method of Mix Design The basic concepts of the Marshall mix design method were originally developed by Bruce Marshall of the Mississippi Highway Department around 1939 and then refined by the U.S. Army. The Marshall stability of the mix design is defined as a maximum load carried by a compacted specimen at a standard temperature of 60 oC.

Asphalt shingles cover about 80% of the homes in the United States. Their popularity is due to their relatively light weight, comparatively low cost, ease of installation, and low maintenance requirements. A typical asphalt shingle is a rectangle about 12-18 in (30-46 cm) wide and 36-40 in (91-102 cm) long.
