US ROUTE 50 DAVID A. BRAMBLE, INC.
Partial depth patching WBL US Route 50.
| David A. Bramble, Inc. is currently resurfacing the west bound lanes of US Route 50 from Queenstown to Kent Narrows. Billy Wetmore is the Paving Foreman and Paul C. Bramble is the Paving Superintendent. This project is scheduled for completion by mid-June 2002 and is one of the four Eastern Shore projects featuring Maryland’s premium surface mix, Stone Matrix Asphalt. The four projects currently under contract to David A. Bramble, Inc. include almost 40,000 tons of SMA. This individual project includes 12,000 tons of 12.5mm SMA using a polymer modified PG76-22 binder. Thirty-seven hundred tons of wedge and level are a 9.5mm Superpave with PG64-22 binder. |

| Dixie Construction performed more than 100,000 square yards of carbide grinding on this project. American Paving Fabrics installed Petromat in the partial depth patches which removed the HMA down to the original rigid pavement. George Bartholomew complimented Harry Boniface and Dixie Construction for achieving an extremely smooth ground surface. George also complemented Kevin McGrath of American Paving Fabrics for a timely and professional installation of the paving fabrics needed to retard reflective cracking of the rigid pavement joints. Billy Wetmore used a Blaw Knox 3200 paver along with DD110 and DD130 Ingersoll-Rand roller to achieve optimal density. MSHA Chief Engineer Douglas Rose noted that the longitudinal joint construction was some of the straightest, best and most consistent he had seen in recent years. |

| George Bartholomew hopes to obtain a ride quality incentive for this excellent project when it is complete. Turn lanes and crossovers are being resurfaced with 12.5mm PG70-22 Superpave to facilitate handwork. This roadway routinely handles the large volume (ADT 69,775) of truck traffic needed to supply Maryland’s Eastern Shore with durable and consumable goods. US Route 50 is the gateway to Maryland’s Atlantic Ocean resort areas. Smoothness and durability requirements on this high profile project necessitated a premium surface mix such as 12.5mm SMA. |
