Drainage Evaluation at the U.S. 50 Joint Sealant Experiment
(American Society of Civil Engineers, 2007)This paper presents an investigation of the subsurface drainage features of the test pavement at the U.S. 50 joint sealant experiment near Athens, Ohio. The concrete pavement incorporates a -
Resilient Modulus Prediction Models Based on Analysis of LTPP Data for Subgrade Soils and Experimental Verification
(American Society of Civil Engineers, 2007)Resilient modulus -
Top-Down Cracking in Asphalt Pavements: Causes, Effects, and Cures
(American Society of Civil Engineers, 2008)A section of I-25 north of Denver was rehabilitated by cold milling the existing surface to a depth of three in. and replacing with new hot mix asphalt. The contractor received bonuses for quality and smoothness and the ... -
Operational Strategy for Advanced Vehicle Location System–Based Transit Signal Priority
(American Society of Civil Engineers, 2007)Future deployments of transit signal priority (TSP) in the United States depend largely on improving TSP strategies to better accommodate transit vehicles while at the same time minimizing the negative impacts on the ... -
Mechanistic Approach for Fiber-Reinforced Flexible Pavements
(American Society of Civil Engineers, 2008)The present study investigates the benefits of reinforcing the subgrade soils in flexible pavements. Three types of Soils A, B, and C, and one type of polypropylene fiber having aspect ratios of 50, 84, and 100 were selected. ... -
Statistical Analysis of In-Service Pavement Performance Data for LTPP SPS-1 and SPS-2 Experiments
(American Society of Civil Engineers, 2007)Observational or experimental studies are designed to investigate the effects of various factors on a response variable. This distinction is important because the latter studies are assumed to provide a firmer basis for ... -
Offline Offset Refiner for Coordinated Actuated Signal Control Systems1
(American Society of Civil Engineers, 2007)This paper presents the concept and implementation of an offline offset refiner, which addresses the problem of uncertain (not fixed) starts/ends of green in the determination of offsets for coordinated actuated signal ... -
Evaluation of Flexible Traffic Separators at Highway–Railroad Grade Crossings
(American Society of Civil Engineers, 2007)Flexible traffic separator systems, widely used to alert motorists to lane restrictions, have been suggested as relatively inexpensive, easily maintainable countermeasures to discourage motorists from driving around the ... -
Pilot Study on Real-Time Calculation of Arrival Type for Assessment of Arterial Performance
(American Society of Civil Engineers, 2007)The -
Evaluation of Optimum Rubblized Depth to Prevent Reflection Cracks
(American Society of Civil Engineers, 2007)Reflection cracking is a common distress in asphalt overlays on cracked concrete pavements. Rubblization, which can minimize reflection cracks, has been used as an efficient rehabilitation method for aged concrete pavements ... -
Dynamic Effects on Moisture Transport in Asphalt Concrete
(American Society of Civil Engineers, 2007)Permeability of an asphalt pavement is one of the most important parameters that have a direct influence on its design life. It is an intrinsic property that relates the average fluid velocity to a constant pressure gradient; ... -
Improved Transition Preemption Strategy for Signalized Intersections near At-Grade Railway Grade Crossing
(American Society of Civil Engineers, 2007)Because the prime objective of the current preemption methods for traffic signals located near highway-railroad grade crossings is to clear vehicles from the crossing, secondary objectives such as maximizing pedestrian ... -
Estimation of the Safety Effectiveness of Lane and Shoulder Width: Case-Control Approach
(American Society of Civil Engineers, 2007)There is a need to better understand and quantify the safety implications of geometric improvements and countermeasures. A commonly accepted measure of safety effectiveness is the crash modification factor (CMF) defined ... -
Assessing the Risk in the Design of Passing Sight Distances
(American Society of Civil Engineers, 2007)Mostly, design methods in transportation engineering do not address the level of risk associated with the design and use of various highway elements. Passing sight distance (PSD) is an example of a highway operational ... -
Influence of Various Material and Traffic Inputs on Flexible Pavement Design Methods for Alabama Roadways
(American Society of Civil Engineers, 2007)Statistical analyses of over 2,000 pavement designs using the 1993 American Association of State Highway Transportation Officials Design Guide was conducted. Variations in traffic levels, and subgrade, base, and hot mix ... -
Mean Profile Depth of Pavement Surface Macrotexture Using Photometric Stereo Techniques
(American Society of Civil Engineers, 2007)Pavement surface texture affects many vehicle and road characteristics; therefore, efforts are needed to develop more advanced techniques for evaluating pavement texture. Photometric stereo techniques are widely used to ... -
Review of How to Make Two-Lane Rural Roads Safer: Scientific Background and Guide for Practical Application by R. Lamm, A. Beck, T. Ruscher, T. Mailaender, S. Cafiso, and G. La Cava
(American Society of Civil Engineers, 2007) -
Development of Linear Mixed Effects Models for Predicting Individual Pavement Conditions
(American Society of Civil Engineers, 2007)Predicting future conditions of pavement plays an important role in pavement management. Prediction for a specific pavement is usually based on the deterioration trend of a group of pavements with similar characteristics, ... -
Use of Nondestructive Test Deflection Data for Predicting Airport Pavement Performance
(American Society of Civil Engineers, 2007)Surface deflections using nondestructive tests (NDTs) were measured prior to and throughout the traffic testing at the U.S. Federal Aviation Administration’s National Airport Pavement Test Facility (NAPTF). The first series ... -
Axial Compression Capacity of Welded-Slip Pipeline Joints
