Three‐Dimensional Surface Texture Characterization of

Abstract: This article investigates the effectiveness of different mathematical methods in descri the three‐dimensional surface texture of Portland cement concrete (PCC) pavements. Ten PCC field cores of varying surface textures were included in the analysis. X‐ray Computed Tomography (CT) was used to scan the upper portion of these cores, resulting in a stack of two‐dimensional

California. The pre-project pavement was older Portland Cement Concrete (PCC) with some slab faulting. Faulting occurs when the concrete slabs become misaligned and disjointed due to heavy truck loads, failing foundations, and/or temperature differentials. Under the Fig. 6: Comparison of overall sound intensity levels for

PCC Pavement - Pavement Interactive

Lean concrete (see Figure 6). Contains less portland cement paste than a typical PCC and is stronger than a stabilized aggregate. Lean concrete bases (LCBs) can be built to as much as 25 - 50 percent of the surface course strength (FHWA, 1999).

Based on profi lograph records of con-crete pavements in California, Hveem (1951) concluded that slab curling was due to the combined eff ect of temper-

Zero-stress temperature and Its implications for long-term

Continuously reinforced concrete pavement (CRCP) is a portland cement concrete (PCC) pavement structure with a continuous longitudinal steel layout. CRCP is forming a major portion of PCC roadway systems in the state of Texas due to its low life cycle cost, ease of maintenance, and durable nature.

Author(s): Monismith, Carl L.; Kim, C.; Lee, E.B. | Abstract: The California Department of Transportation (Caltrans) replaced about 5 kilometers (total 20 lane-kilometers) of concrete pavement on Interstate 15 in Devore, California. The I-15 Devore II rehabilitation project was completed in six weekend closures with around-the-clock construction in early 2007, with partial or full closures of

At a recent Tech Day in May , attendees were able to examine pavement test sections on U.S. 23 in central Ohio, where approximately three miles of portland cement concrete (PCC) in the northbound lanes were part of an SPS-2 experiment to evaluate these five design features: 8-inch versus 11-inch thickness

Pavement Manual: Bonded Concrete Overlay

When constructing a bonded concrete overlay, a new concrete layer is applied to the surface of the existing PCC pavement. This increases the total thickness of the concrete slab, thereby reducing the wheel load stresses and extending the pavement life. There are BCO projects in Texas that have provided an additional 20 yr. of service.
