The New York City Department of Transportation (NYCDOT) Parking Division is responsible for the largest parking meter network in the United States. The efficient operation and maintenance of this system provides an important and sizable source of revenue for New York City. This study addressed the need of the NYCDOT Parking Division to review its current operations and evaluate operability measures. The study was undertaken in coordination with the research unit, the maintenance and revenue collection units, and the computer services unit.

Field experience indicates that wick drains installed vertically in grid fashion do not consistently result in the required degree of consolidation, under construction loading, in the time established in design. Such deviations are often related to variations in soil characteristics that are not fully identified due to limitations of soils investigation and testing.

State-of-the-art technology is available which incorporates shredded scrap tire rubber known as crumb rubber modifier (CRM) as a modifier for asphalt cement in paving mixtures. CRM is the general term to describe all rubber particles obtained from the shredded of discarded tires which are reduced up to a size of 6.35 mm. Two technologies are most commonly used to incorporate crumb rubber in asphalt pavement applications, namely, the wet and dry process.

<p>In New York City, as in other highly urbanized areas, a number of factors make it too difficult to apply pavement management systems methodology in the traditional way: the existence of underground utilities and utility cuts. The potential of future patching which affects pavement performance. The fact that more than 70 % of NYC pavements are composite pavements, which are not suited for Non-Destructive Testing (NDT) analysis techniques. The objective of this project is to develop a NDTbased framework to effectively manage urban pavements at the project level.

This project involved a field campaign and subsequent
data analysis for the Route 30 bridge over the South
Chuctanunda Creek in Montgomery County, NY. The
two purposes of this work were: 1) to make more
detailed measurements of the bridge environment than
we have done in the past to better understand the
energy budget of a curing concrete bridge and 2) to
provide atmospheric boundary conditions to a model
of curing concrete.
New measurements included direct sensible and latent
