Ensure proper expansion joint spacing (typically every 20 feet) and bituminous joint filler application. Pay strict attention to the transition zone where concrete curbs meet asphalt pavement to prevent water infiltration and subsequent frost heave.
The NJDOT Standard Construction Details are a collection of technical drawings and specifications that form the backbone of public works construction across New Jersey. They function as the official blueprint for how various roadway, bridge, and traffic control elements should be built. These details are not merely suggestions; they are legally binding standards adopted by the state.
