A Wirtgen SP 62i slipformer has been used to build roads on the site of a former race circuit in Texas

A Wirtgen SP 62i slipformer has been used for the cost-effective paving of concrete slab in the US state of Texas. The machine has been utilised for construction work in College Station, a town some 150km northwest of Houston, Texas.

The contractor used the SP 62i to pave new lanes on the site of the former Texas World Speedway race circuit.

The site of the race circuit is now being redeveloped to make way for housing and more than 76,000m³ of road will be needed there for the new Southern Pointe residential area. This is being built over an area of 2.6km² over the next 12 years.

In College Station, construction activities began at the south entrance of the new residential area. The inset paver paved the concrete on a lime-stabilised sub-base over a length of 67m in two passes, 11.5 m wide, 200mm thick, and with a crown of 3%.

Larry Young Paving opted for the compact SP 62i model because the machine’s low noise and emissions suit the urban applications in which the contractor carries out most of its work. This compact, two track machine suits paving widths from 3.5m to 7.5m and can handle thicknesses of up to 450mm. However, special paving widths, thicknesses, and options are available if required.
