Pave Ahead Team Provides Solutions to Delaware Road Projects

Luke McHugh, PE, and Kenneth Justice, PE, of NRMCA’s Pave Ahead team recently provided design assistance to DelDOT’s engineering consultant Johnson, Mirmiran & Thompson, Inc. (JMT) which was wrestling with construction issues for one project in design and another already underway. For the Delaware Avenue Separated Bikeway Project with 1.25 lane miles of concrete pavement, McHugh and Justice suggested the engineer specify the use of a laser guided screed to reconstruct the intersections in lieu of precast panels, resulting in significant cost savings while also adhering to the same weekend roadway closure window.
While constructing improvements to 5.6 lane miles of concrete pavement on Elkton Road also in Delaware, JMT encountered a buried approach slab that didn’t match as-built plans. JMT considered a concrete overlay option bonded to the top of the slab crossing Elkton Road. But Justice and McHugh recommended removing the buried section of the approach slab and extending the concrete pavement to meet the remaining slab crossing Elkton Road perpendicularly. This solution resulted in uniform slabs at the tie-in and minimized concerns about longterm durability and maintenance.
