Tools To Reduce Road Impacts

Heavily loaded logging trucks are less likely to leave ruts in forest roads if their tire pressure is reduced, allowing more of the tread to contact the road. The Technology and Development Program helped develop central tire inflation systems that allow heavy trucks to deflate their tires when traveling on gravel roads and reinflate them before traveling on highways.

Spark Arrester Testing

Off-highway vehicles, motorcycles, and chain saws can start forest fires if their exhausts throw sparks. Spark arresters used on these devices must be tested and certified by the Technology and Development Program before they can be used on lands administered by the USDA Forest Service and other Federal agencies.

Water/Road Tools

Careful design of roads, culverts, and bridges can reduce their environmental impacts on streams, lakes, and aquatic organisms. The Water/Road Interaction Series produced by the Technology and Development Program includes videos and reports on the topics of surface drainage, subsurface drainage, and drainage crossings.
