Item Code: SP393
Date of Publication: 2009
Price: $0.00
|
For parking lots and roadways, the selection of paving materials is an important consideration for sustainable development. It is critical to consider all aspects of the project, including the long-term energy costs associated with outdoor lighting systems.
This publication discusses an investigation to evaluate lighting installations for parking lots, using typical light fixture layout patterns to compare the average luminance level and visibility levels for concrete and asphalt pavements, as well as the amount of energy used for the lighting systems. The investigation revealed that the total annualized cost and energy demand of lighting an asphalt pavement is significantly more than for a concrete pavement.

Item Code: PL634
Date of Publication: 2009
Price: $0.00
|
This case study outlines the use of a cement-modified soil for a parallel taxiway at the Muhlenberg County Airport in Greenville, Kentucky. During the design, it was discovered that the soils to support the taxiway embankment were weak and would create issues with stability. Cement modification to a depth of 16 inches was chosen to create a stable platform for embankment construction. At a fifty percent cost savings over traditional methods, cement modification was definitely the right choice in gaining stability. This document presents just how effective cement modification is for providing stability to marginal soils.

|
Item Code: PL632
Date of Publication: 2009
Price: $0.00
|
|
This four page case study describes the use of roller-compacted concrete pavements at the Choctaw Point Terminal in Mobile, Ala. RCC was chosen over other paving options due to (1) RRC’s positive attributes, including the speed of construction, durability, and low maintenance cost, and (2) the excellent track record of RCC at other major terminals. The majority of paving areas received a heavy-duty pavement section consisting of 15.5 inch thick RCC placed in two lifts over 6 inches of cement-stabilized sand. Other areas received a medium-duty pavement section including 8 inches of RCC over 6 inches of cement-stabilized sand. RCC pavement was built for the tough conditions of a busy port facility. The project included a total of 400,000 square yards built in 2008 and 2009. The document discusses the pavement design, RCC mix design, construction methods, and RCC testing.

Thickness Design of a Roller-Compacted Concrete Composite Pavement
|
Item Code: PL633
Date of Publication: 2009
Price: $0.00
|
Many agencies continue to investigate ways of optimizing pavement designs to save money while still providing a durable pavement structure. One such structure that is gaining popularity is the use of roller-compacted concrete (RCC) base with a hot-mix asphalt (HMA) overlay. The RCC provides the primary structural support with HMA surfacing applied to improve ride quality. Such a pavement structure has been referred to as a composite system. When dealing with a composite pavement, one challenge is in determining the structural contribution of the HMA overlay. This publication provides such guidance using examples developed through a mechanistic method.

This 2-page case study describes the use of soil-cement by North Carolina DOT to reconstruct a critical highway on Ocracoke Island following the destruction of Hurricane Isabel in 2003. The pavement was severely undermined by tidal surge and many hours of relentless pounding. The highway needed to be put back into service quickly, and the only way to get construction materials to the island was by ferry. By using cement to stabilize the on-site beach sand, the need to haul in aggregate was eliminated. According to NCDOT, the decision to use soil-cement was "primarily based on economics, logistics, and good performance from the old soil-cement base." Sold in packs of 25.

Item Code: PL398
Date of Publication: 2004
Price: $25.00
|
|
This two-page case study describes the treatment a highly expansive subgrade soil for a couple of county roads in San Antonio, TX. Tests run on soil samples taken from one of the sites indicated plasticity levels in the high 30s. Results showed that an addition of only four percent of cement by volume reduced the PI from 38 down to 16. According to the contractor on the project, cement is similar to lime-treatment; however, with cement overall construction time can be cut in half. The normal five days of curing time and second mixing required for lime is eliminated by using cement. In addition, cement sets-up fast and provides an excellent working surface to support asphalt dump trucks and lay down machines even during wet conditions. Sold in packs of 50.

Cement to the Rescue
|
Item Code: RP424
Date of Publication: 2005
Price: $22.00
|
|
Reprint of an article from the March 2005 issue of Rocky Mountain Construction describing the use of full-depth reclamation (FDR) with cement to reconstruct a deteriorated asphalt parking lot in Westminster, CO. The project consisted of pulverizing and stabilizing the parking lot’s existing 4-inch asphalt surface and clay/sandy clay subgrade to a depth of 12 inches and then resurfacing with 4 inches of asphalt. The original design called for 8% Type C fly ash which was expected to meet the specified 160-psi compressive strength. However, laboratory testing indicated that it would take up to 15% fly ash to meet the strength requirement. Lime was considered, but the “mellowing” period and remixing required for lime would cause unacceptable delays in the construction. Cement proved to be the fastest and most economical solution. Laboratory tests showed that 3% cement resulted in a compressive strength of 295-psi. The article includes a description of the project and quotes from the contractor and others involved in the project. Sold in packs of 50.

City of La Quinta Uses New Microcracking Method on Madison Street Rehabilitation Project
|
Item Code: RP426
Date of Publication: 2005
Price: $15.00
|
|
Reprint of a 4-page article from California Asphalt Magazine, Rehabilitation Issue, April 2005, describing the use of an innovative construction method by the City of La Quinta, California. Concerned with reflective cracking, the City tried a process known as microcracking to minimize the occurrence of cracks that can start in soil-cement base and reflect up through an asphalt overlay. A City project on a one-mile section of Madison Street included the rehabilitation of the failed flexible pavement through full-depth reclamation (FDR) using portland cement followed by the microcracking of the completed base through passes by a vibratory roller that created fine cracks throughout the base, thereby mitigating the occurrence of large problematic shrinkage cracks. The article includes a detailed description of the project, equipment, and testing as well as quotes from the City, contractor, and others familiar with the process. Sold in packs of 25.

Reprint of an article from March 2006 issue of Asphalt Contractor magazine, which reports on the use of full-depth reclamation (FDR) to rehabilitate 150 lane miles of secondary roads in South Carolina. More then 450,000 tons of material was processed using Portland cement as the stabilizing material. Using a conventional reconstruction method, 600,000 tons of material would have been trucked out and into the project. The FDR process allowed the width of the pavement to increase to 24-ft from existing widths that varied from 18 to 22-ft. Depth of the stabilized material was typically 8 to 9-in. Surface treatment consisted of two layers of chip seal followed by a final sand sealer coat to hold the aggregate chips in place. According to the District engineer, when 15 to 25% or more of the designated road requires full-depth patching, it generally becomes a candidate fro the FDR process. The article includes a detailed description of the project, equipment, and benefits of FDR as well as quotes from the District engineer and contractor. 4 pages. Sold in packs of 25.
