Full Depth Paving for Town of Vienna

This is a video of our asphalt crew performing a full depth replacement of Tapawingo Rd. in the Town of Vienna. Full depth replacement is a process where we remove the entire layer of existing asphalt down to the sub base which is the foundation for roadways. Using a Wirtgen 1200 milling machine, we grind the existing asphalt to a predetermined depth and empty the ground up pieces of asphalt (millings) into the bed of a tandem Mack dump truck. The millings are then taken to an asphalt plant where they are recycled, and introduced into a new mix of asphalt. After the milling is complete, the existing sub base is re-compacted and then we will pave the new road way.


Paving a Parking Lot for a Home Owners Association in McLean, VA

This is a video of our asphalt crew paving a parking lot for a Home Owners Association in McLean, VA. Using a Lee Boy asphalt paver and a tandem Mack truck, we dump the new asphalt surface course into the hopper of the paver, and spread the new asphalt on the existing parking lot. The asphalt paver allows us to lay the asphalt in a uniform manner at a predetermined depth; in this case we removed the surface layer of existing deteriorated asphalt to a depth of up to two inches, and replaced it with a new layer of 9.5 mm asphalt surface course. After the asphalt is laid we use an Ingersoll Rand roller to compact the new asphalt and remove any voids of air making the roadway smooth for future traffic.

Placing Concrete Walkways at George Mason University

This video is of our concrete crew at The Patriot Center at George Mason University. Here we removed various walkways leading up to the entrances to the arena. In this process we had to excavate the existing deteriorated concrete. The concrete was excavated to full depth, and we then compacted the existing sub base. Once the sub base was compacted, we installed steel reinforcement using 6″x6″ welded wire mesh. As this was an area that was not accessible to heavy equipment, we had to transfer the new 3500 psi concrete using power buggies. Once the new concrete is dumped from the buggy, we spread it using a metal leveler and then finish the concrete using floats, edging tools, and provide a broom finish to deter the new concrete from being slippery when wet. As concrete expands and contracts throughout the winter and summer months, this can cause existing concrete move slightly over time, which can lead to damaging the edges of new and existing concrete. To eliminate this, we use expansion joints to provide a buffer between the two pieces of sidewalk so that they have room to let mother nature work.
