Since 1892–when the very first concrete pavement was placed in America–concrete pavement technology has been changing, continually evolving to meet current and future needs. These advances happen on many different fronts and are the result of contributions by people and organizations (industry, the public sector, and academia), all working to provide the best choices to meet construction, rehabilitation, and restoration/preservation.
To see more examples of these attributes, please follow the links below to download resources detailing jointed concrete pavements (doweled or undoweled), continuously reinforce concrete pavements, concrete overlays, and precast pavements. Also included are examples detailing technologies such as NGCS, concrete pavement restoration, full-depth reclamation, cement-treated base, and recycled concrete aggregates.

This 100-acre facility, located close to the West Virginia/Kentucky state line, offers industrial and warehousing space; modern and efficient freight container service; and improved access to international rail lines. The natural geologic formation at the site was not ideal for this application, so the project was paved with multiple pavement layers to reduce stresses on the subgrade and prevent excessive settlements.Read More

Located north of San Antonio, this two-lane local road is serves a residential area and light commercial businesses, while also serving as a haul road for the largest quarry operations in the nation. The existing asphalt pavement was described as a “roller coaster” or “mine field,” because of the number and severity of potholes and other distresses. Roller compacted concrete (RCC) provided the right solution.Read More

There are two stitching methods used to repair and strengthen cracks or joints in concrete pavement. The first, and most common, is cross-stitching. Cross-stitching uses deformed tiebars epoxied or grouted into holes drilled at an angle through a crack. The second, slot-stitching, uses deformed tiebars grouted into slots cut across a joint or crack. Each technique is beneficial for certain circumstances. Recommendations on where to use these methods are outlined in this special report.Read More

Load transfer is the ability of a joint or crack in a concrete pavement to transfer load from one slab to the next through shear action. Load Transfer Restoration (LTR) is a rehabilitation technique for increasing the load transfer capability of existing PCC pavement by placement of dowel bars or other mechanical devices across joints or cracks that exhibit poor load transfer.Read More
-
Dowel bars in jointed concrete pavements provide load transfer between slabs at the transverse joints. The improved load transfer reduces slab deflections relative to undowelled joints. These beneficial effects significantly reduce joint faulting, base pumping, and erosion, thus increasing pavement life and providing greater smoothness over the lifetime of the pavement.Read More

For Toyota’s first ever Roller Compacted Concrete (RCC) lot in the United States, the standards were very exacting. After exploring alternatives, Toyota Motors Manufacturing Indiana (TMMI) evaluated but rejected the first two RCC bids. The owner then accepted E&B Paving’s third bid to be the General Contractor for a new container lot.Read More
