By · CommentsLegg and Davis Construction Company has been a family owned contracting business Columbus, Ohio since 1907. They are one of the few businesses that specialize in both asphalt and concrete work as a specialty. In 2006 they purchased a new Lee Boy model 8515 paver manufactured by Lee boy from The McLean Company. It is the latest in the state of the art paving machines built and designed by Lee Boy incorporating sonar based grade control system by Topcon and sonar material handling system. This new paver has an innovative electrically heated screed capable of going out to 15’ wide with heat and vibration and a high speed rubber track not offered by other manufacturers presently. The function controls for the machine is finger tip controlled which allows for ease of movement from right to left side of the machine for easy operation. The nice advantage of this machine is it can be a 2 or 3 man machine operation by either being a Low deck or High deck machine by simply raising the operators control panel. Literally 1 man can run this machine.
Shelly and Sands, Inc Akron-Youngstown Area division lays down 9mm rubberized super pave surface course mix with their new Vogele America 1110wb in Newton Falls, Ohio. The screed was heated electrically to an average temperature of 340-370 degrees to pave and maintain a great looking mat.
Shelly and Sands, Inc Mansfield division utilizes their Companies new Hamm Oscillatory roller model HD 90 V on some of their toughest paving jobs. One recently was the Marion County airport laying a P401 FAA mix 2” thick prior to compaction on a fiber mat product to prevent reflective cracking. Density was being achieved at mat temperatures down to 130 degrees, picking up .5-1.0 points on the nuclear density gauge. A tough FAA density specification is required on the longitudinal joint. This was achieved buy use of the Oscillatory roller at much lower mat temperatures instead of traditional vibratory rollers used in this application at much higher mat temperatures.
Another benefit to the non destructive nature of the roller was smoothing off take off points from a transverse joint.
