Texas State Highway 99—Grand Parkway

State Highway 99, also known as the Grand Parkway, is one of the largest modern infrastructure projects in Texas. Rollcon supplied the cement-treated base to build 54 miles of four-lane roads extending from northwest side of Houston and connecting it to Highway 59 and the Houston Ship Channel. For such an important project for the city and region, Rollcon was chosen to execute the CTB placement due to our expertise in zero-slump placements. The roadways we executed demonstrated one-percent yield and elevation tolerances within an eighth of an inch for an extremely smooth rideability.
