Soil Tracking, Slope Tracking

When large areas are graded, particularly in cut and fill operations, slopes are highly susceptible to erosion, even in light rain events. Exposed areas must be temporarily stabilized with vegetation no more than 14 days after grading, and permanent stabilization is needed to ensure a stable slope when work is complete.
Slopes are often "tracked" with bulldozers or related equipment, creating a series of grooves in the soil perpendicular to the slope direction. This can be effective at resisting erosion during minor rain events and can also provide a place for temporary or permanent seed, fertilizer, and mulch to rest while the seed germinates and takes root.
US 301 in Delaware was constructed over a 3-year period using seven contracts, in addition to advance clearing, tolling, and landscaping. It extends from the Maryland /Delaware State Line to State Route 1, and was opened to traffic on January 10, 2019. It is a 14-mile limited access highway with four interchanges, 28 bridges, and an all electronic tolling (AET) system.
The Delaware T2/LTAP Center provides direct technical assistance, training, and technology transfer to Delaware local agencies relative to their transportation challenges.
